How does a thermopile work?

Thermopiles convert thermal energy into electrical energy. Thermopiles use several thermocouples connected in series or parallel. Thermopiles are used for contactless temperature sensing. The function of a thermopile is to transfer the heat radiation emitted from the object to a voltage output.

What does a thermopile detect?

Thermopiles are used to provide an output in response to temperature as part of a temperature measuring device, such as the infrared thermometers widely used by medical professionals to measure body temperature, or in thermal accelerometers to measure the temperature profile inside the sealed cavity of the sensor.

What is thermopile array sensor?

Thermopile Arrays These arrays provide low resolution image sensing, and can be used as imaging arrays for presence detection, energy conservation, alarm applications and non-contact temperature measurement.

What is difference between thermocouple and thermopile?

The main difference between Thermocouple and Thermopile is their method of measurement. The thermocouple is a thermoelectric instrument, while the thermopile is an instrument that modifies thermal energy into electrical output.

What is the difference between a thermocouple and a thermopile?

What is thermocouple sensor?

A thermocouple is a sensor that measures temperature. It consists of two different types of metals, joined together at one end. When the junction of the two metals is heated or cooled, a voltage is created that can be correlated back to the temperature.

How do you fix a thermopile?

Replacing a Thermopile

  1. Turn off the Gas Supply.
  2. Disconnect the Wires.
  3. Remove the Manifold Door.
  4. Remove the Pilot Assembly and Thermopile Wire.
  5. Place the New Thermopile Wire.
  6. Feed the Wires Through the Manifold Door.
  7. Install the Manifold Component Block.
  8. Reconnect the Thermal Switch Wiring.
