The supply voltage to the transmitter should not exceed 24 VDC.
SAFETY WARNINGS AND IEC SYMBOLS
This device is marked with international safety and hazardous symbols in
accordance with IEC1010. It is important to read and follow all the precautions
and instructions in this manual before operating or commissioning this device as
it contains important information relating to safety and EMC. Failure to follow
all the safety precautions may result in injury and/or damage to your
equipment.

SECTION 1 - INTRODUCTION
The unit has a fixed Emissivity of 0.95 which makes it easy to measure
temperature, requiring no adjustments during installation and use.
The super-compact design, 19 mm OD x 89 mm Length (0.75" OD x 3.5" L) is
ideal to measure temperature in confined, and hard to reach places. The Stainless
Steel housing is NEMA-4 rated. The unit comes with a 1.82 m (6') shielded cable
as standard.
SECTION 2 – INSTALLATION
2.1 – Unpacking
Remove the packing list and verify that you have received all your equipment. If
you have any questions about the shipment, please call the Customer Service at:
1-800-622-2378 or 203-359-2208. We can also be reached on the internet at
omega.com
email: [email protected]
When you receive the shipment, inspect the container and the equipment for any
signs of damage. Note any evidence of rough handling in transit. Immediately
report any damage to the shipping agent.
The carrier will not honor any damage claims unless all the
shipping materials are saved for inspection. After
examination and removing contents, save packing material
and carton in the event reshipment is necessary.
The following items are supplied in the box:
• The infrared transmitter, OS136 with the 1.82 m (6') shielded cable.
• Two Mounting Nuts
• User’s Guide
Introduction

NOTE:
The model OS136AModel is a very low-cost, super-compact infrared
transmitter. Itmeasures temperature via non-contact, and provides an analog
outputproportional to the measured temperature. The OS136AModel is offered
in twotemperature ranges: -18 to 204ºC (0 to 400ºF) and 149 to 538ºC (300 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.

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.
 The Emissivity is fixed at 0.95. No adjustment is necessary. If the target
Emissivity is less than 0.95, you can place a masking tape or paint the target
area with flat black paint to raise the surface Emissivity to 0.95.
 Make sure the output load is within the product specification.
Figure 3-1. Optical Field of View
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, OS136-WC (Fig 3-5 & 3-6). 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 25°C to 50°C ambient temperature.

3.3 - Atmospheric Quality
Environments with smoke , dust, and fume 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, OS136-AP (Fig 3-3).
The following figures show the Mounting Bracket (OS136-MB), Air Purge Collar
(OS136-AP), Stainless Steel Housing, Water/Air Cool Jacket (OS136-WC), and
the Water/Air Cool Jacket Assembly.
