NOTES:

OS100 Series

Section 1 - Introduction

The low cost OS101 mini-infrared transmitter provides non-contact

temperature measurement for industrial applications. The unit measures a

temperature range of -18 to 538°C (0-1000°F) and provides a linear analog

output of either 4-20 mA, 0-5 VDC, K type TC, 1 mV/°C, or 1 mV/°F.

The new OS102 mini-infrared transmitter has all the functions of OS101

plus a built-in LED display that shows the measured temperature in

degrees F or degrees C which is switchable in the field.

The miniature sensor head design 2.5 cm dia. x 6.3 cm Length (1" x 2.5") is

ideal for measuring temperature in confined, and hard to reach places.

The aluminum sensor head as well as the rugged electronic housing (Die

cast Aluminum) are NEMA-4 rated.

The sensor head is connected to the electronic housing via a 1.82 m (6 feet)

shielded cable as standard. The unit provides field adjustable alarm

output.

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

Customer Service at:

1-800-622-2378 or 203-359-1660. We can also be reached on the internet:

omega.com e-mail: [email protected]

When you receive the shipment, inspect the container and 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 including the sensor head and the 1.82 m

(6 feet) shielded cable

• User's Manual

• Mounting Nut

Here are the Features of OS101 and OS102 infrared transmitters:

2.2 Electrical Connection

Sensor Head Cable - The Sensor head is pre-wired to a 1.8 m (6 feet)

shielded cable. Plug & lock-in the male connector to the mating female

connector on the aluminum housing.

Power & Output Connection - Open the cover of the main aluminum

housing. Slide the cable through the strain relief and connect the wires to

the terminal block on the board as shown in Fig. 2-1. For Alarm output

connection, refer to Fig. 2-2.

3.2 Ambient Temperature

The Sensing head can operate in an ambient temperature of 0 to 70°C (32

to 158°F). The Sensing head in the high temperature model (-HT) can

operate in an ambient temperature of 0 to 85°C (32 to 185°F) without any

cooling required. The Sensing head can operate up to 200°C (392°F) using

the water cool jacket accessory OS100-WC (See Fig. 3-6).

There is a warm up period of 3 minutes after power up. After the warm

up period, temperature measurement can be made.

When the ambient temperature around the sensor head changes abruptly,

the sensor head goes through thermal shock. It takes a certain amount of

time for the sensor head to stabilize to the new ambient temperature. For

example, it takes about 30 minutes for the sensor head to stabilize going

from 25°C to 50°C (77 to 122°F) ambient temperature.

The sensor head dimensions are shown in Fig. 3-2.
