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 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 and
remove the laser sighting accessory from the sensor
head.

Alarm Adjust and Alarm Switch)
• Set the Slide Switch on the main board to the Alarm
position.
• 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
(20-4)
538°C, (0 to 1000°F) [10.4mA= 40 x100

• Set the Alarm Slide Switch back to the Real Time
Position.
• I f the temperature reading is below the alarm
setpoint, the Alarm Output stays low, otherwise it
goes high (Alarm Condition).

OS137A
Using This Quick Start Manual
Use this Quick Start Manual with your OS137A
Series Miniature Infrared Transmitter for quick
installation and basic operation. For detailed
information, refer to the User’s Guide (Manual #
M4015).
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.
Electrical Connection
The shielded cable provides the power and
output connections. General Wiring Diagram
shows the wiring diagram for different analog
outputs. Alarm Output Wiring Diagram shows
alarm output connections.
Connect the body of the OS137A to Earth Ground. Leave the
shield disconnected and insulated at the end of the cable.

WARNING!
Alarm Output Wiring Diagram
Connecting the Green alarm lead
to ground, or to any load exceeding
100mA, will result in damage to the
OS137A and void the warranty.
If the alarm output is not
being used, it must be left
disconnected and insulated.
• The power and output connections are made (see
General Wiring Diagram)
• The target is larger than the optical field of view of
the transmitters (see Optical Field of View)
• 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 (see Location of Emissivity & Alarm Adjust
and Alarm Switch). 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

Atmospheric Quality
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. 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.
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.
The following figures show the Air Purge Collar
(OS137-AP), Stainless Steel Housing and Water/
Air Cool Jacket (OS137-WC), with built-in air purge
collar.

General Information
The OS137A Series is a precision, miniature
infrared transmitter. It measures temperature
via non-contact, and provides an analog output
proportional to the measured temperature. The
OS137A Series is offered in three temperature
ranges: 0 to 100°C (32 to 212°F), -18 to 260°C
(0 to 500°F) and -18 to 538°C (0 to 1000°F). 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.
