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.

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

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.
