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.

Asked by: Jerry in water
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 temperature@omega.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 .
