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.

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.

3.3 Atmospheric Quality

Environments with smoke, dust, and fumes 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, OS100-AP, See
Fig. 3-7.

3.4 Measuring Temperature

Before starting to measure temperature, make sure that the following
check list is met:

 The power and analog output connections are made (Fig. 2-1).

 The sensor head is connected to the main unit.

 The slide switch (SW1) on the main board is set to real time (Fig. 3-1).

 The target is larger than the optical field of view of the sensor head

(Fig. 3- 3 ).

 The emissivity adjustment on the main board is set properly (Fig. 3-1).

 The output load is within the product specification.

On OS102 transmitters, follow these additional steps:

 The temperature display is set to °F or °C (Fig. 3-4)

 For 4-20mA output models, make sure an output load is added, ie. 250

ohms.

3.5 Alarm Setting

The unit provides 0-100% alarm set point adjustment. Here is an example
of an alarm setting.

• An OS101-MA (4/20 mA output), the alarm is to be set at 400°F

temperature.

• Connect the alarm output as shown in Fig. 2-2.

• Set the slide switch (SW1) on the main board to the Alarm position.

• Measure the analog output, and set the Potentiometer P4 until the
output reads 10.4 mA which is 40% (400°F) of the temperature range.

40 x (20-4)

[10.4mA =

100

+ 4]

• Set the slide switch (SW1) back to the Real Time position.

• If the temperature reading is below the alarm set point, the alarm
output stays high, otherwise it goes low.

On the OS102, you can set the alarm set point directly based on the
temperature display.

3.6 Adding Extension Cable

You can add extension cable between the Sensor Head and the main
electronic housing up to 15.2 m (50 feet). After adding the extension cable,
the Zero input potentiometer, P3 may be re-adjusted. (See Fig. 3-1, for
proper analog output reading)

The following figures show the mounting bracket (OS100-MB), Water
cooling jacket (OS100-WC), Air purge collar (OS100-AP), DIN Rail
Mounting adapter (OS-100-DR), and the main aluminum enclosure. The
DIN Rail Mounting adapter (OS100-DR) is mounted to the bottom of the
main aluminum enclosure using two 4-40 screws.

4.1 Warning and Cautions

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 operation the laser sight accessory

• Never point the laser accessory at a person

• Keep out of the 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 sensor head. This
accessory is only used for alignment of the sensor head to the target area.
After the alignment process, the accessory has to be removed from the
front of the sensor head before temperature measurement.

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
so 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. See Fig. 4-1 for reference.
