The Working Principle of a Thermopile Pyranometer

WebThe 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. WebDec 3, 2012 · Otherwise how does your pilot flame look while running? If the pilot flame is getting pulled away from your thermopile sensor after the fireplace gets a bit of draft going you may need to replace your pilot assembly. The pilot flame should be direct and intense on your thermopile and thermocouple sensors (much like a blow torch flame).
