Thermosensors TS105-1 / TS105-2 THERMOPILES are used for non-contact surface temperature measuring. Any object emits infrared radiation. The radiation power is increasing with growing surface temperatures. Based on this relation, THERMOPILES measure the emitted power and determine the object’s temperature precisely. Function Principle THERMOPILES are based on the Seebeck effect, which is used since a long time for conventional thermocouples. The application of micromechanics and thin film technology allows the production of miniaturized and cost effective sensor elements. absorption area (hot junctions) SiNx-membrane silicon substrate (cold junctions) A multitude of thermojunctions deposited on a silicon substrate is connected in series to form a THERMOPILE. The hot junctions are thermally insulated from the cold junctions on the substrate by etching a self-supporting extremly thin membrane. An absorbing layer on the hot junctions transforms the incoming radiation into heat. A voltage proportional to the radiation is generated by the thermoelectric effect. The sensors are delivered in TO5-packages. Different housings and filter types can be selected to find an optimal solution for each application. Chips without housing are available as well.
