IR Thermopile vs. Pyroelectric RC Groups

20170407· IR Thermopile vs. Pyroelectric. Hi all. I am thinking about building a UAV autopilot using the method of IR horizon sensing. However I am finding it very hard to source the solid state thermopiles that most people use. I was thinking about using a pyroelectric sensor like those used in PIR security systems. I believe that those systems react to a change in temperature of the detected object ...

Thermopile and Infrared Temperature Sensors | TE Connectivity

Thermopile IR Temperature Sensors. Thermopile sensors are designed to measure temperature from a distance by detecting an object''s infrared (IR) energy. The higher the temperature, the more IR energy is emitted. The thermopile sensing element, composed of small thermocouples on a silicon chip, absorb the energy and produce an output signal. A ...

Advantages and Disadvantages of Thermopile sensor

Definition of Thermopile sensor: The sensor device which uses noncontact based temperature sensing with the help of more than one thermocouples is known as thermopile sensor. It has more voltage output compare to normal traditional thermocouple sensor device. It uses concept of absorption of infrared radiation from the object being measured. The electrical output of thermopile sensor is ...

Optimization of the Geometry of a Thermoelectric ...

components: a small camping stove, butane fuel canister, and a thermopile constructed of type E (NickelChromium / Constantan) thermocouples. The thermopile also acted like a flashback arrestor, preventing the flame from propagating back to the propane/butane fuel canister. During testing, the fuel exited the canister, flowed through the thermopile and then ignited. Changing the geometry of ...

Why Both Thermocouple and Thermopile? CR4 Discussion Thread

20181011· Today I was troubleshooting a propane residential gas firepace for a friend and found it uses both a thermocouple and a thermopile. I have been repairing commercial kitchen gas appliances full time since 2006 and have never seen both used in the same piece of equipment. Seems like a waste of money/parts. In the commercial food service equipment if there is a thermopile it is used to operate ...
