1. Introduction
General Description
The IDP10-A Differential Pressure Transmitters measure the difference between two pressures
applied to
opposite sides of a silicon strain gauge microsensor within the sensor assembly. This microsensor
converts differential pressure to a change in resistance. The resistance change is then converted to
a 4 to 20 mA signal proportional to differential pressure or to the square root of differential
pressure. This measurement signal is transmitted to remote receivers over the same two wires that
supply power to the transmitter electronics.
The transmitters are often used for measuring fluid flow across a primary device such as an orifice
plate, but
can also be used for other types of differential pressure measurements such as liquid level, interface
level, or density measurements. For more detailed information on the principle of operation of
the transmitter, refer to document TI 037-096.

Process Wetted Materials
Diaphragm: 316L ss, Co-Ni-Cr, Hastelloy C, Monel, gold plated 316L ss, or tantalum
Covers and Process Connections: 316 ss, carbon steel, Hastelloy C, Monel, or pvdf inserts
Pressure Seals: Refer to MI 020-369.
Process Pressure and Temperature Limits for Pressure Seals
Refer to MI 020-369.
Electrical Connections
Field wires enter through 1/2 NPT, PG 13.5, or M20 threaded entrances on either side of the
electronics housing. Leads terminate under screw terminals and washers on the terminal block
in the field terminal compartment. To maintain RFI/EMI, environmental, and
explosionproof ratings, unused conduit connection must be plugged with metal plug
(provided), inserted to five full turns.
Field Wiring Reversal
Accidental reversal of field wiring will not damage the transmitter, provided the current is
limited to 1 A or less by active current limiting or loop resistance. Sustained currents of 1 A
will not damage the electronics module or sensor but could damage the terminal block
assembly and external instruments in the loop.
Adjustable Damping
The transmitter response time is normally 1.0 second or the electronically adjustable setting
of 0.00 (none), 2, 4, or 8, seconds, whichever is greater, for a 90% recovery from an 80%
input step as defined in ANSI/ISA S51.1.
Output Signal
4 to 20 mA dc linear, or 4 to 20 mA dc square root, software selectable, locally configurable
using pushbuttons on the transmitter.
Zero and Span Adjustments
Adjustable at the transmitter using the local display. An optional external self-contained
moisture sealed pushbutton assembly allows local resetting of zero without removing housing
cover (except on model IDP10-AS).
Powerup Time
Less than 2.0 seconds for output to reach the first valid measurement, then at the electronic
damping rate to reach the final measured variable value.
Supply Current
Power supply must be capable of providing 22 mA current. Ripple of up to 2 V pp
(50/60/100/120 Hz) is tolerable, but instantaneous voltage must remain within specified
range.

1. Introduction
MI IDP10-A – February 2016
Electrical Ground Connections
The transmitter is equipped with an internal ground connection within the field wiring
compartment and an external ground connection at the base of the electronics housing. To
minimize galvanic corrosion, place the wire lead or terminal between the captive washer and
loose washer on the external ground screw. If shielded cable is used, earth (ground) the shield
at the field enclosure only. Do not ground the shield at the transmitter.
Test Points
The banana plug receptacles (designated CAL) can be used to check transmitter output.
Measurements should be 100 to 500 mV dc for 0 to 100% transmitter output.
HHT Terminals
As the top terminal is blocked, this transmitter does not communicate with the PC20, PC50,
HART Communicator, or IFDC.
Product Safety Specifications
!
DANGER
To prevent possible explosions and to maintain flameproof, explosionproof, and dustignitionproof protection, observe applicable wiring practices. Plug unused conduit
opening with the provided metal pipe plug. Both plug and conduit must engage a
minimum of five full threads for 1/2 NPT connections; seven full threads for M20
and PG 13.5 connections.
!
WARNING
To maintain IEC IP66 and NEMA Type 4X protection, the unused conduit opening
must be plugged with the metal plug provided. Use a suitable thread sealant on both
conduit connections. In addition, the threaded housing covers must be installed. Turn
covers to seat the O-ring into the housing and then continue to hand tighten until the
cover contacts the housing metal-to-metal.
NOTE
1. These transmitters have been designed to meet the electrical safety description
listed in Table 2. For detailed information or status of testing laboratory
approvals/certifications, contact Global Customer Support.
2. Wiring restrictions required to maintain electrical certification of the transmitter
are provided in “Wiring” on page 30.

Installation of Flow Measurement Piping
Figures 18 and 19 show typical installations with horizontal and vertical process pipes.
The transmitters are shown below the level of the pressure connections at the pipe (usual
arrangement, except for gas flow without a seal liquid), and with filling tees in the lines to the
transmitter (for a seal liquid).
If the process fluid being measured must not come in contact with the transmitter, the transmitter
lines must be filled with a suitable seal liquid (see procedure in next section). In such a case, the
transmitter must be mounted below the level of the pressure connections at the pipe. With steam
flow, the lines are filled with water to protect the transmitter from the hot steam. The seal liquid
(or water) is added to the lines through the filling tees. To prevent unequal heads on the
transmitter, the tees must be at the same elevation and the transmitter must be mounted vertically
(as shown). If a seal liquid is not required, elbows can be used in place of the tees.
Tighten drain plugs and optional vent screws to 20 Nm (15 lbft). Tighten the four process
connector bolts to a torque of 61 Nm (45 lbft).
Note that the low and high pressure sides of the transmitter are identified by an L-H marking on
the side of the sensor above the warning label.
With medium viscosity seal liquids and/or long transmitter lines, larger valve sizes should be used.
NOTE
1. With a horizontal line, pressure connections at the pipe should be at the side of the
line. However, with gas flow without a seal liquid, connections should be at top of
line.
2. With a vertical line, flow should be upwards.
3. For liquid or steam flow, the transmitter should be mounted lower than the
pressure connections at the pipe.
4. For gas flow without a seal liquid, the transmitter should be mounted above the
pressure connections at the pipe; for gas flow with a seal liquid, the transmitter
should be mounted below the pressure connections.
5. It is recommended to use snubbers in installations prone to high levels of fluid
pulsations.

Filling System with Seal Liquid
If the process fluid being measured must not come in contact with the transmitter, the transmitter
lines must be filled with a suitable seal liquid. The procedure to do this is as follows:
1. If the transmitter is in service, follow the procedure “Taking a Differential Pressure
Transmitter Out of Operation” on page 35.
2. Close both process shutoff valves.
3. Open all three valves on the 3-valve manifold.
4. Partially open the vent screws on the transmitter until all air has been forced out of the
transmitter body and lines. Close the vent screws.
5. Refill the tee connections. Replace the plugs and close the bypass valve. Check for
leaks.
6. Follow the procedure “Putting a Differential Pressure Transmitter Into Operation” on
page 34.
!
CAUTION
To prevent loss of seal liquid and contamination of process fluid, never open both
process shutoff valves and manifold shutoff valves if the bypass valve is open.
Positioning the Housing
The transmitter housing (topworks) can be rotated up to one full turn in the counterclockwise
direction when viewed from above for optimum access to adjustments, display, or conduit
connections. Housings have either an anti-rotation screw or a retention clip that prevent the
housing from being rotated beyond a safe depth of housing/sensor thread engagement.
!

Wiring the Transmitter to a Control Loop
When wiring a transmitter with 4 to 20 mA output signal, the supply voltage and loop load must
be within specified limits. The supply output load vs. voltage relationship is:
RMAX = 47.5 (V - 11.5) and is shown in Figure 25.
NOTE
The relationship when the optional shorting bar is used is:
RMAX = 46.8 (V - 11).
Any combination of supply voltage and loop load resistance in the shaded area can be used. To
determine the loop load resistance (transmitter output load), add the series resistance of each
component in the loop, excluding the transmitter. The power supply must be capable of
supplying 22 mA of loop current.

To wire one or more transmitters to a power supply, proceed with the following steps.
1. Screw in cover lock (if present) and remove the field terminals compartment cover by
rotating it counterclockwise.
2. Run signal wires (0.50 mm2 or 20 AWG, typical) through one of the transmitter
conduit connections. Use twisted single pair to protect the 4 to 20 mA output from
electrical noise. Screened (shielded) cable may be required in some locations.
NOTE
Do not run transmitter wires in same conduit as mains (ac power) wires.
3. If shielded cable is used, earth (ground) the shield at the power supply only. Do not
ground the shield at the transmitter. Cut and/or tape the shield so it cannot contact
the metal housing.
4. Plug unused conduit connection with the 1/2 NPT, PG 13.5 or M20 metal plug
provided (or equivalent). To maintain specified explosionproof and dustignitionproof protection, plug must engage a minimum of five full threads. Thread
sealant is recommended.
5. Connect an earth (ground) wire to the earth terminal in accordance with local
practice.
!
CAUTION
If the signal circuit must be earthed (grounded), it is preferable to do so at the negative
terminal of the dc power supply. To avoid errors resulting from earth loops or the
possibility of short-circuiting groups of instruments in a loop, there should be only
one earth in a loop.
6. Connect the power supply and receiver loop wires to the “+” and “–” terminal
connections.
7. Connect receivers (such as controllers, recorders, indicators) in series with a power
supply and transmitter as shown in Figure 26.
8. Reinstall the cover onto the housing by rotating it clockwise to seat the O-ring into
the housing and then continue to hand tighten until the cover contacts the housing
metal-to-metal. If cover locks are present, lock the cover per the procedure described
in “Cover Locks” on page 30.
9. If wiring additional transmitters to the same power supply, repeat Steps 1 through 8
for each additional transmitter. The setup with multiple transmitters connected to a
single power supply is shown in Figure 27.

4. Calibration
NOTE
1. For best results in applications where high accuracy is required, rezero the
transmitter output once it has stabilized at the final operating temperature.
2. Zero shifts resulting from position effects and/or static pressure effects can be
eliminated by rezeroing the transmitter output.
3. When checking the zero reading of a transmitter operating in the square root
mode, return the output to the linear mode. This eliminates an apparent instability
in the output signal. Return the transmitter output to the square root mode after
the zero check is complete.
4. After calibrating transmitters operating with a 4 to 20 mA (or 1 to 5 V dc) output
signal, check the underrange and overrange output values to ensure that they
extend beyond 4 and 20 mA (or 1 and 5 V dc) respectively.
General Calibration Notes
1. Each transmitter is factory characterized over its full rated differential pressure range.
One benefit of this process is that every transmitter can measure any applied
differential pressure within its range limits regardless of the calibrated range. The
applied differential pressure is measured and converted into an internal digital value.
This digital value of differential pressure is always available whether the transmitter is
calibrated or not. Calibration assures that the transmitter rated accuracy is achieved
over the calibrated range.
2. The internal digital value of differential pressure can be displayed on the local display,
and converted to a 4 to 20 mA analog output signal.
3. Each transmitter is factory calibrated to either a specified or a default calibrated range.
This calibration optimizes the accuracy of the internal digital value of differential
pressure over that range. If no range is specified, the default range is zero to the sensor
upper range limit (URL).
4. There is an independent trim on the digital-to-analog conversion stage. This trim
allows for slight adjustment of the 4 and 20 mA outputs. This compensates for any
slight difference that exists between the transmitter mA output and an external
reference device which is measuring the current.
 The mA trim does not affect the calibration or the reranging of the transmitter
and does not affect the internal digital value of pressure or the transmission or
display of measured pressure.
 The mA trim can be done with or without pressure applied to the transmitter.
41
MI IDP10-A – February 2016
4. Calibration
5. The transmitter database has configurable values for both lower range value (LRV)
and upper range value (URV). These stored values are used for two functions:
defining the calibrated range and reranging without pressure.
a. Defining the Calibrated Range:
 When either CAL LRV or CAL URV is initiated from the pushbuttons, the
transmitter expects that the differential pressure applied at the time the button
is pressed is equal to the LRV or URV value respectively.
 This function trims the internal digital value of differential pressure; that is, it
performs a calibration based on the application of accurate differential
pressures equal to the values entered for LRV and URV in the transmitter
database.
 This function also sets the 4 and 20 mA output points; that is, the 4 and 20
mA points correspond to the values of LRV and URV in the database.
 If the transmitter is configured for reverse range, the 20 and 4 mA points
correspond to the LRV and URV respectively.
b. Reranging Without the Application of Pressure:
 Since the transmitter continually determines an internal digital value of the
measured differential pressure from the lower range limit (LRL) to the upper
range limit (URL), the 4 and 20 mA output points can be assigned to any
range values (within the span and range limits) without application of
pressure.
 The reranging function is accomplished by entering new database values for
LRV and URV.
 Reranging does not affect the calibration of the transmitter; that is, it does not
affect the optimization of the internal digital value of differential pressure over
a specific calibrated range.
 If the reranged LRV and URV are not within the calibrated range, the
measured values may not be as accurate as when they are within the calibrated
range.
6. LCD Indicator
 The display can show any measured differential pressure in selected units
regardless of the calibrated range and the values of LRV and URV (within the
limits of the transmitter and display). The display can also be 0 to 100 percent.
 If the measured differential pressure is outside the range established by the LRV
and URV values in the database, the display shows the measurement but also
continually blinks to indicate that the measurement is out of range. The current
signal is saturated at either the low or high overrange limit respectively but the
display continually shows the pressure.
 Custom flow units for display, including 0 to 100 percent, are used when the
transmitter is in square root mode.
42
4. Calibration
MI IDP10-A – February 2016
7. Zeroing the Transmitter
 Zeroing does not affect the span.
 When the transmitter is zeroed to compensate for installed position effect, the
transmitter may have either LRV differential pressure applied (CAL LRV) or zero
differential pressure applied (CAL AT0). If the range is zero-based, either method
produces the same result. However, if the range is not zero-based, it is
advantageous to have both methods available.
For example, consider a differential pressure transmitter having a range of 50 to
100 psig. If it is not feasible to vent the transmitter to atmosphere for zeroing (or
to bypass the high and low sides for zeroing), it may be zeroed while the LRV
differential pressure of 50 psi is applied by using the CAL LRV function. On the
other hand, if the transmitter has been installed but there is no pressure in the
process line yet (or the high and low sides can be connected by a bypass valve), it
can be zeroed while open to atmosphere (or bypassed) by using the CAL AT0
function.
a. Zeroing with LRV Pressure Applied (CAL LRV):
 Before using this zeroing function, apply a differential pressure to the
transmitter equal to the value of LRV stored in the transmitter database.
 When you zero the transmitter, the internal digital value of differential
pressure is trimmed to be equal to the value of LRV stored in the database and
the mA output set to 4 mA.
 If zeroing is done when the applied differential pressure is different from the
LRV value in the database, the internal digital value of differential pressure is
biased by the difference in the values but the output is still set at 4 mA.
 The CAL LRV (and CAL URV) function should be used when calibrating a
transmitter for a specific range with known input differential pressures applied
for the LRV and URV.
b. Zeroing with Zero Pressure Applied (CAL AT0):
 Make sure that the applied differential pressure is at zero. This means venting
the transmitter to atmosphere.
 When you zero the transmitter, the internal digital value of the differential
pressure is trimmed to be equal to zero and the mA output set to an
appropriate value such that the mA output is a nominal 4 mA when the LRV
pressure is applied later.

Calibration Setup
The following sections show setups for field or bench calibration. Use test equipment that is at
least three times as accurate as the desired accuracy of the transmitter.
NOTE
It is not necessary to set up calibration equipment to rerange the transmitter to a
different range. The transmitter can be accurately reranged by simply changing the
lower range value and the upper range value, which are stored in the transmitter
database.

Field calibration is performed without disconnecting the process piping. In order to do this, you
must have a bypass and shutoff valves between the process and the transmitter and one of the
following:
 Access to the process connections on the nonprocess side of the transmitter
 The optional vent screw in the side of the process covers.
If the transmitter is to be removed from the process for calibration, refer to “Bench Calibration
Setup” on page 46.
For field calibration, an adjustable air supply and a pressure measuring device are required. For
example, a dead weight tester or an adjustable clean air supply and pressure gauge can be used.
The pressure source can be connected to the transmitter process connection with pipe fittings or it
can be connected to the vent screw assembly using a calibration screw. The calibration screw has a
Polyflo fitting and can be used for pressures up to 700 kPa (100 psi). It is available as Part

MI IDP10-A – February 2016
To set up the equipment, refer to Figure 32 and use the following procedure.
1. If the transmitter is in operation, follow “Taking a Differential Pressure Transmitter
Out of Operation” on page 35.
!
CAUTION
With liquid service, drain both sides of transmitter to avoid calibration errors.
2. If a calibration screw is being used, remove the vent screw and replace it with the
calibration screw. Connect the pressure source to the calibration screw using
6 x 1 mm or 0.250 inch tubing.
If a calibration screw is not being used, remove the entire vent screw assembly or drain
plug (as applicable) from the high pressure side of the transmitter. Connect calibration

Zero Adjustment Using External Zero Button
An optional external zero adjustment mechanism in the electronics housing allows local
“rezeroing” of the transmitter output without removing the electronics compartment cover. The
mechanism is magnetically activated through the housing wall to prevent moisture from entering
the enclosure. Zeroing is accomplished when the external zero button is depressed. The external
zero button does a CAL AT0 calibration (at zero differential pressure).
To use this feature:
1. Unlatch the external zero button by turning it 90° in a counterclockwise direction so
that the screwdriver slot lines up with the two holes in the face of the adjacent part.
Do not push the button in with the screwdriver while doing this.
2. Press the button with zero differential pressure applied to the transmitter or the bypass
valve open and the transmitter at a nonzero static pressure.
3. The display indicates ZEROED. If EX ZERO is disabled, or the transmitter is not
on-line, the display reads Bad Key.
4. If additional rezeroing is required, wait 20 seconds and repeat Step 2.
5. Relatch the external zero button by turning it 90° in a clockwise direction to prevent
accidental pressing of the button. Do not push the button in with the screwdriver
while doing this.
