Robertshaw 1980-018 Snap-Fit Thermocouple 18 Inch

The Robertshaw 1980-018 Snap-Fit Thermocouple is a temperature sensor specifically designed for HVAC equipment. It converts heat into a small voltage signal (25 to 30 millivolts) using the principle of thermoelectricity. This voltage signal is sent to the HVAC control board, which then regulates heating or cooling output based on the temperature reading.These lightweight (0.11 lbs) and typically 18-inch long thermocouples are ideal for various HVAC applications due to their ease of installation and replacement. Their snap-fit design simplifies installation in gas furnaces, water heaters, and other HVAC systems.
