Thermosensors
TS 118 - 3 / TS 118 - 4
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 silizium-substraet
(hot junctions) SiNx-membrans (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 extremely 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 TO05 packages. Different housings and filter types
can be selected to find an optimal solution for each application. Chips without housing are available as
well.
