Thermopile | Working Principle | THE INSTRUMENT GURU

“ Thermopile is used to measure temperature difference. it convert thermal energy into electrical energy. it uses several thermocouples connected in series or parallel. Thermopiles are used for contact-less temperature sensing. The function of a thermopile is to transfer the heat radiation emitted from the object to a electrical voltage output.

THERMOPILE SENSOR FOR CONTACTLESS TEMPERATURE

The calibration of the thermopile output signal can be carried out in these process steps: • Measurement of thermopile voltage at high temperature setpoint to determinate the thermopile sensitivity s. • Measurement of thermopile voltage at low temperature setpoint to determinate offset voltage caused by electronics and signal processing chain. This step can be skipped in dependence of ...
