OS136 Series Miniature Low-Cost Non-Contact Infrared Temperature Sensor/Transmitter 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.
1 Introduction 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.
Installation 2 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: Accessories Description Mounting Bracket Water/Air Cooling Jacket Air Purge Collar Lase
3 Operation 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.
Operation 3 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. 12.7 (0.5) 3.2 (1/8) 12.7 (0.5) 50.0 (1.97) 90° Ø 19 (0.
