WebDec 15, 2024 · The job of the thermocouple is to keep the pilot lit. It does this by sending a tiny electric current to a sensor on the gas valve signaling the valve to stay open. The thermocouple can do this because, in its probe, it contains two different metals, and a voltage is generated when one of them is heated. WebThermocouples are simple tem-perature sensors consisting of two wires made from dissimilar alloys. These devices are simple in construc-tion and easy to use. But, like any …

WebFeb 21, 2024 · The thermocouple stops the flow of gas whenever there is a power outage. It closes the valve of the gas line that provides gas to the pilot light. Therefore, the pilot light goes out when the power goes out. You say that the thermocouple requires [electrical] power to operate. See Above. WebUsing your flame source such as a lighter, and place the tip of the thermocouple into a flame. As it heats up, attach one lead of the meter to one side of the thermocouple. Then attach the other lead to the end of the thermocouple by the igniter. A working thermocouple will produce a reading of 25 to 30 millimeters.

WebThermocouples can be used for a wide variety of applications in the food and beverage industry including Clean-In-Place sensors, Penetration Probes, Oven Control, Food Chain Monitoring, Hotplate Control and Monitoring and Steam Kettle temperature control. Thermocouples for Extruders Extruders require high temperature and high pressures. WebThermocouples are designed to detect a pilot light’s loss of heat and close the gas valve to prevent a gas leak. Replacing a thermocouple is a relatively easy fix that can take less than two hours. This guide reviews how to replace a thermocouple to ensure gas appliances stay in good working order, as well as how to relight a pilot light.
