· How do I know if my thermopile is bad? If you can't get the flame to light at all, and you're sure the gas is on, there's probably an obstruction in the pilot tube. If the flame lights and goes out when you release the gas control knob after holding it in for the recommended 20 to 30 seconds, that's the sign of a thermocouple malfunction.
· Thermopile vs Thermocouple. The key distinction between the thermocouple and the thermopile is that the thermocouple is a thermoelectric device and the thermopile is a device that transforms electrical energy into thermal energy. Thermocouple. A thermocouple consists of two different metals connected in series. In order to detect radiation, one junction is blackened to absorb …

· The main difference between Thermocouple and Thermopile is that the Thermocouple is a thermoelectric device and Thermopile is a device that converts thermal energy into electrical energy.
based on the Seebeck effect, which has historically been utilized for conventional thermocouples. The development of micromechanics and thin film technology has allowed for the design and manufacture of miniaturized and cost-effective thermopile sensor elements. The thermopile voltage V TP is then determined by: • Object temperature T obj • Emissivity of the object ε obj • Ambient ...
Thermopile is composed of pair of thermocouples or more arranged in series or parallel. It produces higher voltage output compare to single thermocouple. Moreover unlike thermocouple which is contact based temperature sensor, thermopile is non contact based temperature sensor device.
· Both the thermocouple and thermopile dont have any label on it. Can someone help me what thermopile to buy and thermocouple if i also need to buy it. Should I also change the thermocouple. The thermopile is the one near the pilot light so I assume that's the one that went bad. Thanks, Save Share. Reply. J. jmon · Super Moderator. Joined Nov 5, 2012 · 6,792 Posts #2 · 8 mo …
thermopile vs thermoelectric - what is the difference. thermopile From the web: which thermocouple do i need; what thermopile used for
In heating systems a thermocouple is one junction of metals that when heated by a pilot flame generates approximately 25 mv and holds open an electromagnetic valve to allow gas to pass as long as there is a pilot. A second valve in the valve train...
Thermocouples in series form a thermopile. Thermoelectric generators are used for creating power from heat differentials. Peltier effect. The Seebeck circuit configured as a thermoelectric cooler. When an electric current is passed through a circuit of a thermocouple, heat is evolved at one junction and absorbed at the other junction. This is known as the Peltier Effect. The Peltier effect is ...
· Can someone tell me the difference between the Thermocouple and the Thermopile and what their functions are exactly. I know the Thermocoupler produces mili volts from the heat that is put on it from the pilot light and this is sent to the gas valve to prevent a explosion if the pilot light is not lit and the gas valve is opened, but I am not sure what the Thermopile does exactly. Thanks, John ...
thermocouple vs thermopile What is a thermocouple? The thermocouple is essentially an electrical device that consists of two wires made of a different metal that are joined together. They functioned similarly to electrical conductors, producing electrical outputs at varying temperatures. Heat enters one section, circulates, and travels down each wire. It generates electricity when it back up ...

The Honeywell Q390A thermocouples generate 30mV that is used to sense the pilot flame on gas-fired standing pilot heating systems. Q313. The Honeywell Q313 Thermopile generates 750 mV, which is sufficient to operate an automatic millivolt gas control system, independent of any outside power source. Q335 . The Honeywell Q335 Thermocouple is a quick dropout thermocouple that generates 30mV. …
· RTDs vs. Thermocouples. Temperature range: Thermocouples are best for working at high temperatures. New manufacturing techniques have improved the measurement range of RTD probes, but more than 90% of RTDs are designed for temperatures below 400°C. In contrast, some thermocouples can be used at up to 2500°C. Cost: Thermocouples are generally cheaper than …
