2 Introduction
2.1
Appropriate use
Series 140 pyrometers are digital pyrometers for non-contact temperature measurement:
The IPE 140 is used for measurements on metals, graphite, or ceramics at low temperatures or if
extreme long temperature ranges are required.
The IPE 140/39 is used for non-contact temperature measurement of metal parts in flame
heated furnaces. The narrow spectral range of 3.9 µm avoids the influence of humidity and CO2
and enables a correct measurement through flames and combustion gases. Also humidity and
CO2 do not have any influence on measurements with long measuring distances. Another
application is the measurement of glass if a small penetration into the glass is necessary (e.g.
glass drop). Measurement errors caused by partially cooled down surfaces can be avoided.
The IPE 140/34 is used for non-contact temperature measurement of plastic films; especially
extremely thin Polyethylene or Polypropylene films, with a minimum material thickness of only
30 µm.
The IPE 140/45 is used for the temperature measurement of CO2 containing gases above
approx. 500 °C. As a gas is not a solid object, a certain penetration path into the gas is necessary
for an exact temperature measurement. The path length is dependent on the temperature, the
concentration of CO2 and the pressure. For example: on atmosphere condition, approximately
4% CO2, a penetration depth of 2-3 m is necessary, for concentrations of min 10% CO2, 0.5 m is
sufficient.

Accessories (Optional)
Numerous accessories guarantee easy installation of the pyrometer. The following overview
shows a selection of suitable accessories. You can find the entire accessory program with all
reference numbers in Chapter 9, Reference numbers.
Mounting
For mounting and aligning the pyrometer to the
measured object a mounting angle or a ball and
socket mounting is available.
The ball and socket mounting is an easy way to
align the pyrometer to the measured object. The
quick-clamping-screws of the ball and socket
mounting enable an easy and fast adjustment of
the pyrometer in all directions.

Cooling
The pyrometer can be used in ambient
temperatures outside of the specifications if
preventive maintenance is taken.
The cooling plate is used to protect the
pyrometer from heat coming from the front. The
completely covered water cooling jacket made
from stainless steel protects the pyrometer if
exposed to a hot environment. It is designed for
ambient temperatures up to 180 °C.
Displays
In addition to the built-in temperature indicator
of the pyrometer, LumaSense offers several
digital displays which can also be used for
remote parametrizing of the pyrometer.

DA 6000
LED large display
Miscellaneous
The air purge protects the lens from
contamination with dust and moisture. It has to be
supplied with dry and oil-free pressurized air and
generates an air stream shaped like a cone.
The scanning attachment SCA 140 moves the
measuring beam of the pyrometer from 0 to 12°.
This angle is adjustable to smaller values. The
scanning frequency is as well adjustable from 1 to
5 Hz. In most cases the scanning attachment
SCA 140 is used as a peak picker for measuring
smaller objects like thin wires which may be
moving.
The 90°-mirror enables the capture of objects at
an angle of 90° to the pyrometer axis.

3.1
Electrical Installation
The series IPE 140 is powered by a voltage of 24 V
(14 to 30 V) DC or AC (48 to 62 Hz). The instrument
needs some time to warm up. This time depends on
the ambient temperature and connected power
supply. During this time, the display indicates
“wait”. The analog output is 0 mA. After the warm
up time, the display shows the measuring
temperature. To switch off the instrument,
interrupt the power supply or unplug the electrical
connector.

After connecting the power supply, the display shows the internal firmware version for
approximately 1 s. The green control light on the rear cover is swiched on. The control light
blinks as long as the laser targeting light is switched on (only for instruments equipped with a
targeting light).
To meet electromagnetic requirements (EMV), a shielded connecting cable must be used. The
shield of the connecting cable has to be connected only on the pyrometer's side. One side of the
power supply (switch board) the shield must be open to avoid ground loops.
LumaSense offers connecting cables, which are not part of standard scope of delivery.The
connecting cable has wires for the power supply, interface, analog output, external laser switch,
and external clear of maximum value storage via contact (see section 9, Reference numbers) and
12-pin connector. The cable includes a short RS232 adapter cable with a 9-pin SUB-D connector
for direct PC communication. This adapter is not used in combination with the RS485 interface.
Note: At object temperatures below 150 °C and emissivity smaller than 90%, the
pyrometer needs another half an hour for warm-up until the final accuracy is reached.
Otherwise a sufficient accuracy is reached after approximately 10 min.

Connector pin J
The connector pin J can be used for 3 different functions:
1) Operating mode contact: During the warm-up of the pyrometer (after connection to
the power supply, the LED display on the converter indicates “wait”), the pin J is
connected to the power supply voltage. This voltage is connected by a relays switch
(max. 0.2 A at 50 V) to pin K (power supply voltage). This relays switch opens when the
warm-up is finished and the pyrometer is in operating mode. For that reason this pin can
be used as operating mode contact.
2) External clearing of the maximum value storage: When the pyrometer is in
operating mode, pin J can be used for external clearing of maximum value storage (see
section 5.4). To clear the maximum value storage, connect pin J for a short time to pin K
(power supply voltage).
The function “external clearing” is activated with the following conditions:
Warm-up is finished (no “wait“ indication on the display)
The clear time is set to “extern“ (see section 5.4)
3) Hold function: when the hold function mode is activated the current temperature
reading is frozen as long as J and pin K are connected (see section 5.4 clear time for
the maximum value storage).
3.1.2
Connecting the pyrometer to a PC
The pyrometers are equipped with a serial interface RS232 or RS485 (switchable at the
pyrometer). Standard on a PC is the RS232 interface. Only one pyrometer can be connected if
the interface is set to RS232. Only short distances can be transmitted with RS232 and
electromagnetic interferences can affect the transmission. The RS485 transmission is relatively
free of problems, allows long transmission distances, and enables you to connect several
pyrometers to a bus system.
If RS485 is not available at the PC, it can be realized with an external converter which converts
the RS485 to RS232 for a standard connection to a PC. When using a converter RS485
RS232,
ensure that the converter is fast enough to receive the pyrometer’s answer to an instruction of
the master. Most of the commonly used converters are too slow for fast measuring equipment.
It is recommended to use the LumaSense converter -7520 (order no. 3 852 430). With a slow

RS485 connection, it is also possible to set a wait time at the pyrometer to delay the response of
a command to the pyrometer (see 5.10 Wait time tw).

the fully extended objective (S = 26), the smallest aperture value for objective length S = 0. Intermediate values have to be
interpolated.
The spot sizes, mentioned in the table above, will be only achieved at the adjusted distance.
Decreasing or increasing the measuring distance enlarges the spot size.
Note: The InfraWin program includes a calculator (Spot Size calculator“) that roughly
estimates the unknown values.
Note: The measuring object has to be at least as big as the spot size of the

Emissivity (Emi)
For a correct measurement, it is necessary to adjust the emissivity. Emissivity
is the relationship between the emission of a real object and the emission of
a black body radiation source (this is an object which absorbs all incoming
rays and has an emissivity of 100%) at the same temperature. Different
materials have different emissivities ranging between 0% and 100% (settings
at the pyrometer between 10 and 100%, the set value is indicated on the
display).
Display
of the
adjusted
emissivity
Additionally, the emissivity depends on the surface condition of the material,
the spectral range of the pyrometer, and the measuring temperature. The emissivity setting of
the pyrometer has to be adjusted accordingly. Typical emissivity values of various common
materials for the two spectral ranges of the instruments are listed below. The tolerance of the
emissivity values for each material is mainly dependent on the surface conditions. Rough
surfaces have higher emissivities.

temperature of the air around the pyrometer is normally the ambient temperature
53 °C (127 °F)
of the measured object. Should the measured object be placed in an area with a
higher wall temperature (e.g. inside a furnace), the measurement might be falsified (probably
too high temperature indication). This influence can be compensated by pre-setting the ambient
temperature of the object (pre-setting within the measuring range of the instrument).
Attention: This method only improves the results if the ambient temperature at
the place of the measured object is always constant and the emissivity is well
known.
5.3
Exposure time (t90)
The exposure time is the time interval when the measured temperature has to be
present after an abrupt change so that the output value of the pyrometer reaches
a given measurement value. This is the time it takes to reach 90% of the recorded
temperature difference. In the “min” position, the device operates using its time

If the maximum value storage is selected and the measuring object has a low emissivity and the
measuring temperature is at the beginning of the range, a higher exposure time must be chosen
to prevent measurement errors. Longer exposure times can be used for the measurement of
objects which have rapidly fluctuating temperatures to achieve constant temperature reading.

Clear time of the maximum value storage (tClear)
If the maximum value storage is always switched on, the highest last temperature
value will be displayed and stored. As such, it may be beneficial to periodically
clear and reset the stored maximum values in order to obtain new temperature
readings.
This feature is particularly useful when fluctuating object temperatures cause the
display or the analog outputs to change too rapidly, or the pyrometer is not
constantly viewing an object to be measured. In addition, it may also be beneficial
to periodically delete and reset the stored maximum values.

The following settings are possible:

At off, the maximum value storage is switched off and only momentary values are
measured.
0.01...25 s: If any clear time between 0.01 s and 25 s is set, the maximum value is estimated and
held in double storage mode. After the entered time, the storage will be deleted.
extern:
The external clearing can be activated and used within your own software (see
section 8, Data format UPP®) or via an external contact (for connection see 3.1.1
Pin assignment of the male socket on the back of the pyrometer). In this
case, the storage operates only in single storage, because only a single deletion
mechanism is used.
auto:
The auto mode is used for discontinuous measuring tasks. For example, when
objects are transported on a conveyer belt and pass the measuring beam of the
pyrometer only for a few seconds. Here the maximum value for each object has to
be indicated. In this mode, the maximum value is stored until a new hot object
appears in the measuring beam. The temperature which has to be recognized as
“hot“ is defined by the low limit of the adjusted sub range. The stored maximum
value will be deleted when the temperature of the new hot object exceeds the low
limit from of the sub range by 1% or at least 2 °C. If a lower limit is not entered,
the maximum value storage will be deleted whenever the lower level of the full
measuring range has been exceeded.
Hold:
The function hold enables you to freeze the current temperature reading at any
moment. To use this function, anexternal push button or switch has to be connected
(which holds the temperature reading as long as the contacts are closed).
Operation note: depending on the settings, the maximum value storage either works in single
storage mode or in double storage mode:
Single storage: the single storage is used when you want to reset the stored value using
an external impulse via one contact closure from an external relay (i.e. between two
measured objects). The relay contact is connected directly to the pyrometer between pins J
and K. This mode allows a new value to be established, after each impulse from the reset
signal.
Double storage: when entering the reset intervals via push buttons or PC interface, the
double storage is automatically selected. This mode utilizes two memories in which the
highest measured value is held and is deleted alternately in the time interval set (clear time).
The other memory retains the maximum value throughout the next time interval. The
disadvantages of fluctuations in the display with the clock frequency are thereby eliminated.

Note:
5.5
In the command structure, the maximum storage comes after the exposure time.
This results in:
clear time the adjusted response time is useless
clear times must be at least 3 times longer than the response
time
only maxima with full maximum value can be recorded, which
appear at least 3 times longer than the response time.

You have the opportunity to choose a subrange (minimum 51 °C) within the basic measuring
range of the pyrometer. This subrange corresponds to the analog output. From describes the
beginning of this measuring range, to the end of the range.
Additionally, with the setting of a subrange, it is possible to fulfill the requirements of the
“auto” clear mode of the maximum value storage (see above).

purposes. First, it is necessary to connect each instrument separately to give it an
97
address. After that, all instruments can be connected and addressed individually. If
parameters may be changed simultaneously on all pyrometers, the global Address 98 can be
used. This allows you to program all pyrometers at the same time, regardless of the addresses
that have already been assigned. If the address of a pyrometer is unknown, it is possible to
communicate with it using the global Address 99 (connect only one pyrometer).
5.8
Baud rate (Baud)
The transmission rate of the serial interface in Baud (Bd) is dependent on the
length of the cable. A standard cable length with RS232 for 19200 Bd is 7 m, and
with RS485, it is 2 km. The baud rate is reduced by 50% if the transmission distance
is doubled.

In the lower part of the window, the connection with the preset baud rate can be checked. Here
the command was sent 100 times with 19200 baud. It has taken 0.799 seconds without
transmission errors.
Emi: AutoFind: If the true temperature of the measured object is known, you can calculate the
emissivity of the measured object using the Emi:
AutoFind function:
A measured temperature is displayed with the
current set emissivity (in this example 100%)
(here: 71.7 °C).
If you press Emi: Autofind a window will open
which allows you to enter the "true"
temperature (here 100 °C).
Once the temperature entry has been entered
and confirmed with Calculate, InfraWin will
then calculate the emissivity which occurs with
the new temperature (here 33.0%). This is
displayed immediately and can be used for
further temperature measurement.
6.5 Measurement online trend
The measurement function
allows you to access a
number of input tabs located on the left side
of the screen. The main or home tab is the
Output Screen. You can toggle the input tabs
on and off by clicking them. This window
displays:
temperature as graphical diagram
internal temperature of the
instrument
current temperature
quantity of the measured values and file size of the current measurement
The example shows a sample reading over the period of approximately 15 seconds with a
temperature range between 40 and 105 °C. The final temperature (at the end of the reading) is
99.9 °C.
The Mark Zone button allows you to color mark a temperature range for easier recognition.
The Threshold button allows you to set a temperature value as a baseline to prevent recording
values above or below the baseline temperature. This allows you to keep the output file size
small.
The Scaling Trend button allows you to scale temperature trend view.
Series IPE 140 Manual
Software InfraWin
29
Note: The measuring values of “measurement online trend” are automatically saved
as "standard.i12". Should you need to edit the data later, you need to save the file as
another .i12-file because old values are over-written when a new measurement is
taken.
Files from older program versions (.i10-files) can be opened and saved as .i12.
6.6 Listing (analyzing)
For analyzing the
measured values in
this field, all measured data appears in a
numeric list.
The column between time and
temperature provides a time resolution
of milliseconds. The value specifies the
time in seconds after midnight (0:00 h).
The amount of data depends on the
frequency that readings were taken
(settings at 6.9 PC sampling rates). As the
amount of data increases, so does the
amount of storage space required to
save it. In order to save room, all .i12 data files are stored by a binary code.
6.7 Output .TXT file (analyzing)
The same file as under Output listing may be converted into a text file and
can be easily opened, for example with Microsoft Excel. With the standard
import settings, Excel automatically formats the columns accordingly (with tabs as separators).
6.8 Trend output (analyzing)
The graph’s curve depicts the temperature
change over time within the specified
temperature range.
Additionally, other information appears in
this window; such as recorded time (x-axis)
and temperature in degrees (y-axis) as well
as the time and temperature at the
vertical cursor line which can be dragged
with the mouse.
Selecting the Trend output initially causes
all the saved data to be displayed.
If the data exceeds an amount that can be
reasonably represented, you may zoom in on a partial segment using the mouse (such as the
segment represented in the example). Under Total you can return to the representation of the
entire curve.

Software InfraWin
30
Note: The last reading is saved in the standard.i12 file and automatically appears in
this form upon opening Listing or Trend output.
Selecting file open with another file, the previous file will be overwritten and replaced by the standard.i12 file.
6.9 PC sampling rate (time interval between two
measurements)
This function sets a time interval. After
each interval, one measured value is
stored on the PC. Longer time intervals will result in
creating smaller stored file sizes. This function is mainly
used for long term measurements.
6.10 Spot size calculator
The InfraWin Spot Size Calculator
calculates the data for the nonfocused regions. To calculate data, enter the values
of aperture D, focused measurement distance a,
and focused measuring field diameter M as found
in the documentation relating to the optics
supplied with your specific pyrometer.
After entering the aperture and the main spot size,
the input of interim values calculates spot sizes in
different measuring distances of the fixed optics.
6.11 Search I/O Module
The I/O Module allows
accessories to connect to the
software and is used to
trigger measurement externally or to send a
signal (like a relay) under certain conditions.

7 Maintenance
7.1
Cleaning the window
Because there are no moving parts in the Series 140 pyrometer, the only regular maintenance
required is a periodic inspection of the front window for build-up of foreign particles which, in
time, can influence the energy received by the instrument. The Series 140 pyrometer has a “Dirty
Window” warning alarm feature that can measure the current window/optical path
transmission and provide a contact closure alert when the window transmission falls below the
user set point.
The Series 140 pyrometer window is not water soluble and can be cleaned with standard lens
tissue dampened with a camera-store lens-cleaning solution. A soft blower/brush (also at
camera stores) should be used to remove any grit on the window before you rub the lens with
lens tissue and solution.
Attention: NEVER CLEAN A SERIES 140 PYROMETER WINDOW WITH A DRY
TISSUE OF ANY KIND! The only time dry lens tissue may be used is to dry a window
which has already been cleaned with wet lens tissue.
7.2
Optics replacement
Series 140 pyrometers are equipped with a focusable optics. This optics can be changed against
another. Replacement optics for different measuring distances can be used without recalibration
of the instrument. However, replacement may be necessary if the lens is scratched or the
pyrometer will be used for other measuring distances.
Replacement:
Only the lens will be replaced for changing the focusable
optics. The fixing ring has to be removed with a suitable
objective wrench. After removing the old lens, put in the
new one with the convex side to the front. Fix the lens
with a new fixing ring. On the inside of this ring is the
sticker with the optics data.
For differentiation they are marked with a color mark at
the border of the lens:
Focusable optics 0-PE
Focusable optics 1-PE
Focusable optics 2-PE

8 Data format UPP (Universal Pyrometer
Protocol)
Software commands can be exchanged directly with the pyrometer through an interface using
suitable communication software or by using the Test function located in the Pyrometer
Parameters window of the InfraWin software package.
The data exchange occurs in ASCII format with the following transmission parameters:
•
The data format is: 8 data bits, 1 stop bit, even parity (8,1,e) no handshake;
•
The device responds to the entry of a command with output (such as the measuring
value) + CR (Carriage Return, ASCII 13), to pure entry commands with ok + CR, or no +
CR.
•
Every command starts with the 2-digit device address AA followed by two lower case
command letters and finished with CR.
Example Read Command: Entry: “00em“ + CR
The emissivity setting ( ) of the device with the address 00 is returned.
Answer: “0970“ + CR means Emissivity = 0.97 or 97.0%
•
The ASCII parameter “X” indicates a change to be made in a parameter. When used, the
command contains the new value.
Example Write Command: Entry: “00emXXXX“ + CR
The parameter used for the emissivity setting ( ) with the address 00 is changed.
Answer: “00em0853“ + CR changes the Emissivity to 0.853 or 85.3%
A “?” after the lower case command letters answers with the limits of the respective
settings (only at setting commands, not at query commands).
Example Read Limits Command: Entry: “00em?“ + ˜CR!
Answer: Could be 00501000 + <CR>, which means that E can vary between 0.050 and
1.000 (or 5% and 100%)

Requirements to the master system during half-duplex operation:
1. After an inquiry, the bus should be switched into a transmission time of 3 bits (some older
interfaces are not fast enough for this).
2. The pyrometer's response will follow after 5 ms at latest.
3. If there is no response, there is a parity or syntax error and the inquiry has to be repeated.

10 Troubleshooting
Before sending the pyrometer for repair, try to find the error and to solve the problem with the
help of the following list.
Temperature indication too low
Incorrect alignment of the pyrometer to the object
New correct alignment to achieve the maximum temperature signal (see 3.2)
Measuring object smaller than spot size
check measuring distance, smallest spot size is at nominal measuring distance (see 3.3)
Measuring object is not always in the measuring spot of the pyrometer
Use max. value storage (see 5.4)
Emissivity set too high
Set lower correct emissivity corresponding to the material (see 5.1)
Lens contaminated
Clean lens carefully (see 7.1)
Temperature indication too high
Emissivity set too low
Set lower correct emissivity corresponding to the material (see 5.1)
The measurement is influenced by reflections of hot machine parts
Use mechanical construction to avoid the influence of the interfering radiation
Measuring errors
Indicated temperature is decreasing during the use of the pyrometer, contamination of the
lens
Clean lens. Recommendation: use of air purge (see 7.1)
Indicated temperature is decreasing during the use of the pyrometer, although the air purge
unit is used. Probably compressed air is not clean or air failed
Clean the lens and use clean, dry and oil free compressed air
Air contamination in the sighting path between pyrometer and object
Change position of the pyrometer with a clean sighting path (if necessary use a ratio
pyrometer)
HF-interferences
Correct the connection of the cable shield (see 3.1)
Instrument overheated
Use cooling jacket with air or water cooling (see 3.1)
Temperature Indication is fluctuating, probably caused by changing emissivity
Wrong pyrometer type, use of ratio pyrometer recommended
Laser targeting light
Laser targeting light fails
Instruments max. Temperature is exceeded. Use cooling jacket (see 2.6)
Note: The wavelength band of the IPE 140 series reacts at low measuring temperatures
to incandescent lamps or very bright daylight (not valid for fluorescent tube). For a
correct measurement strong external light to the measured object should be avoided.
