OMEGA’s compact high performance industrial infrared sensor/ transmitter model OS137 provides variety of features and options packaged into a small Stainless Steel housing. The standard features are adjustable Emissivity, 10 to 1 optical field of view, adjustable alarm set point and voltage output to drive external relays, and six pre-selected analog outputs that can easily be interfaced to all meters, controllers, dataloggers, recorders, computer boards, and PLCs. The unit comes with two hex nuts, 1.8 m (6') shielded cable for power and output connections, and complete operator’s manual.

How far away from the target can this be installed? Can that distance be constantly changing? Like reading the temperature in a tank where the level changes.

Optical field of view of the OS137A series which replaces the OS137 is 10:1 .
Area at the spot size will be the location where the average temperature is measured .
The spot size will increase in a 10:1 ratio as the distance from the sensor to target is increased.
The spot size needs to be smaller than area that you wish to measure .
To help us determine the appropriate IR sensor for your application ,please email a description of your application to email@example.com . For example ,
Temperature range min and max ?
Size of the object that is being measure ?
Distance of the sensor to the object ?
Ambient temperature of the IR sensor ?
Material that is being measured ?
Is there dust , steam, smoke in the area ?
Indoor or outdoor application ?
Any other details specific to the application .
