Thermopiles are used for contactless
temperature measurement. The measurement principle is based
on the detection of infrared radiation, using micro-machined
devices in silicon based technology. The device`s inherent
DC coupling characteristic allows the operation without
mechanical chopper. Many applications in different markets
such as medical, automotive, appliance industry and security
systems demonstrate the unique relation of high precision to
price. Applications include thermometers, microwave ovens,
room air conditioners, toasters, hair dryers, pyrometers,
car climate controls, gas-detection and presence detection
products.
