SECTION 1 - INTRODUCTION

The model OS136 series is a very low-cost, super-compact infrared transmitter. It
measures temperature via non-contact, and provides an analog output
proportional to the measured temperature. The OS136 series is offered in two
temperature 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.

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: [e-mail]

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

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.

SECTION 4 - LASER SIGHT ACCESSORY

4.1 – Warning and 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 HERE MAY RESULT IN
HAZARDOUS RADIATION EXPOSURE.

• DO NOT LOOK AT THE LASER BEAM COMING OUT OF THE LENS OR
VIEW 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 OUT OF REACH OF ALL CHILDREN

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 such 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).
