Thermopile Infrared Sensors
Heimann Sensor offers a wide range of thermopile sensors for non-contact temperature measurements and gas detection. Thermopiles consist of many thermocouples that are usually connected in series. They generate a small electric voltage when exposed to infrared (IR) radiation or heat. We produce sensor chips in different sizes. Small sensor chips like 0.6x0.6 mm² and 0.76x0.76 mm² are best for remote temperature measurements due to their optimized performance-cost ratio. The bigger chips like 1.2x1.2 mm² or even 2.1x2.1 mm² are ideally suited for gas detection. They provide enough signal to measure even high gas concentrations.
Besides single element sensors in various packages from SMD to small TO-46 and TO-39, we also produce sensors with two or four elements for gas concentration measurements.
All TO-packaged sensors can be equipped with a lens to reduce the field of view (FOV) to measure from larger distances or to provide a smaller measurement spot for more accurate temperature detection.

Thermopile Infrared Sensor Modules
Heimann Sensor's thermopile modules consist of a thermopile sensor or thermopile array with an integrated ASIC for signal conditioning. The ASIC amplifies the small sensor's voltage and provides either an analog or a digital output. In the case of an analog output, you receive the amplified sensor voltage value. In the case of a digital output, it is possible to select between voltage and temperature value.All modules have an integrated linear temperature reference voltage. This voltage (in the analog case) or voltage value (in the digital case) can be obtained from a separate output channel
