CAUTION & SAFETY INFORMATION

If the equipment is used in a manner not specified in this manual, the protection

provided by the equipment may be impaired.

The Installation category is one (1).

There is no user replaceable fuse in this product.

The output terminals of this product are for use with equipment (Digital meters,

chart recorders, etc.) which have no accessible live parts. Such equipment should

comply with all the applicable safety requirements.

Do not operate the equipment in flammable or explosive environments.

The unit comes with a 1.82 m (6') shielded cable for power and output

connections. The cable is a multi-conductor, 24 AWG stranded wire with the

rating of 600 VDC, 205ºC, (401°F) Teflon®insulation.

Power must be disconnected before making any electrical connections.

The recommended power supply should be VDE or UL approved. Rating:12-24

VDC @ 50 mA min. power with overload protection.

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.

IEC Symbol Description

Caution - Refer to the accompanying

document(s).

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.

The following describes the ordering information:

OS136 – * – ** , where

- * means:

-1 : -18 to 204ºC (0 to 400ºF) Temperature range

-2 : 149 to 538ºC (300 to 1000ºF) Temperature range

- ** means:

-MA : 4 to 20 mA current output

-V1 : 0 to 5 Vdc output

-V2 : 0 to 10 Vdc output

-K : K type thermocouple output

-MVC : 10 mV/ºC output

-MVF : 10 mV/ºF output

The following table lists the optional accessories:

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.
