WebbSelect one of the 8 letter-designated thermocouple types from the console, type any voltage (mV) within the thermocouples range into the Thermocouple (mV) window and press calculate. The calculator will produce the NIST thermocouple table temperature value for that voltage along with the sensitivity or Seebeck coefficient (dV/dT). WebbThermopile. A thermopile is defined as several thermocouples connected in series. For example, a thermopile with three sensing junctions is shown below: As T 2 is increased, the output voltage increases significantly. The advantage of a thermopile (as compared to just one sensing junction) is increased sensitivity.

WebbThis output voltage is directly proportional to the power of the incoming radiation. Since a large number of thermopiles are typically connected in series, voltages of several µV to V are reached. In general, a thermopile sensor consists of three elements: an absorber, the sensor element and a cooling body to dissipate the incoming heat. WebbThe thermopile is nothing but thermocouples connected in series or parallel. When the infrared radiation falls on the thermopile surface, it gets absorbed and converts into heat. Voltage output is produced in proportion to the incident infrared energy. The detector uses this output to determine the temperature, which gets displayed on the screen.
