Introduction
SECTION 1 - INTRODUCTION
The OS137 Series is a precision, miniature infrared transmitter. It measures
temperature via non-contact, and provides an analog output proportional to the
measured temperature. The OS137 Series is offered in three temperature ranges:
0 to 100ºC (32 to 212ºF), -18 to 260ºC (0 to 500ºF) and -18 to 538ºC (0 to 1000ºF).
The analog output is offered as 4 to 20 mA, 0 to 5 Vdc, 0 to 10 Vdc, 10
mV/degree C or F, or K type thermocouple.
The unit provides adjustable emissivity from 0.5 to 1.0, 10 to 1 optical field of
view, and field adjustable alarm output.
The super-compact design, 25.4 mm OD x 127 mm length (1.0" OD x 5.0" L) is
ideal to measure temperature in confined, and hard to reach places. The Stainless
Steel housing is NEMA-4 rated. The unit comes standard with a 1.82 m (6')
shielded cable.
SECTION 2 – INSTALLATION
2.1 – Unpacking

Operation
SECTION 3 – OPERATION
3.1 – Measuring Temperature
Before starting to measure temperature, make sure the following check list is met:
The power and output connections are made (Fig 2-1).
The target is larger than the optical field of view of the transmitter (Fig 3-1).
Use the Laser Sighting accessory (optional), to align the transmitter to the
center of the target area.
Remove the End Cap to get to the Emissivity Single Turn Pot (Fig. 3-2). Set
the Emissivity Pot based on the target surface. Then put back the End Cap.
Make sure the output load is within the product specification.

3.2 – Ambient Temperature
The transmitter can operate in an ambient temperature of 0 to 70°C (32 to 158°F)
without any water cool jacket. It can operate from 0 to 200°C (32 to 392°F) with
the water cool jacket accessory, OS137-WC (Fig 3-6 & 3-7). It can operate up to
110°C (230°F) with air cooling.
There is a warm up period of 1 to 2 minutes after power up. After the warm up
period, temperature measurement can be made.
When the ambient temperature around the transmitter changes abruptly, the sensor head
goes through a thermal shock. It takes a certain amount of time for the sensor head to get
stabilized to the new ambient temperature. For example, it takes about 30 minutes for the
transmitter to stabilize from the 25°C to 50°C (77°F to 122°F) ambient temperature.
3.3 - Atmospheric Quality
Environments with smoke, dust, and fumes dirty up the optical lens, and cause
erroneous temperature readings. To keep the surface of the optical lens clean, the
air purge collar accessory is recommended, OS137-AP (Fig 3-4).
The following figures show the Mounting Bracket (OS137-MB), Air Purge Collar
(OS137-AP), Stainless Steel Housing and Water/Air Cool Jacket (OS137-WC),
with built-in air purge collar.

Alarm Setting
The unit provides 0-100% alarm setpoint adjustment. Here is an example
of an alarm setting:
• An OS137-3-MA (4/20 mA output), the alarm is to be set at 204°C
(400°F) temperature.
• Connect the alarm output as shown in Fig. 2-2.
• Remove the End Cap to get to the Alarm Switch and the Alarm Adjust
(Fig. 3-2).
• Set the Slide Switch on the main board to the Alarm position (2).
• Measure the analog output, and adjust the Alarm Potentiometer until
the output reads 10.4 mA which is 40% (204°C, 400°F) of the
temperature range -18 to 538°C, (0 to 1000°F)
[10.4mA = 40 x (20-4) + 4]
100
• Set the Alarm Slide Switch back to the Real Time position (1).
• If the temperature reading is below the alarm setpoint, the Alarm
Output stays low, otherwise it goes high (Alarm Condition).
• The Alarm Output can drive an external mechanical relay.

4.1 – Warnings and Caution
CAUTION:
You may receive harmful laser radiation exposure if you do
not adhere to the warnings listed below:
• USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF
PROCEDURES OTHER THAN THOSE SPECIFIED IN THIS GUIDE MAY
RESULT IN HAZARDOUS RADIATION EXPOSURE.
• DO NOT LOOK AT THE LASER BEAM COMING OUT OF THE LENS OR
VIEW IT DIRECTLY WITH OPTICAL INSTRUMENTS – EYE DAMAGE CAN
RESULT.
• USE EXTREME CAUTION WHEN OPERATING THE LASER SIGHT
ACCESSORY.
• NEVER POINT THE LASER ACCESSORY AT A PERSON.
• KEEP THE LASER SIGHT ACCESSORY OUT OF REACH OF ALL
CHILDREN.
WARNING:
Do not attempt to open the laser sight accessory. There are no
user serviceable parts inside.
4.2 – Operating the Laser Sight Accessory
The laser sight accessory screws onto the front of the transmitter sensor head.
This accessory is only used for alignment of the transmitter head to the target
area. After the alignment process, the accessory has to be removed from the front
of the transmitter head before temperature measurement is made.
The laser sight accessory is powered from a small, compact battery pack
(included with the accessory). Connect the battery pack to the accessory using
the cable provided. Aim at the target, and turn on the battery power using the
slide switch on the battery pack. Adjust the sensor head position so that the laser
beam points to the center of the target area. Turn off the battery pack, and
remove the laser sighting accessory from the sensor head (Fig 4-1).
