Robertshaw 1980-048 Snap-Fit Thermocouple 48 Inch

The Robertshaw 1980-048 Snap-Fit Thermocouple is a safety sensor used in various gas-fired HVAC equipment like furnaces and water heaters. It works by converting heat into a small electrical voltage (25-35 millivolts) that increases as the temperature rises. This voltage signal is sent to the HVAC control system, which uses it to regulate the gas flow and ensure safe operation. The Robertshaw 1980-048 is 48 inches long, weighs only 0.15 pounds, and features a convenient snap-fit design for easy installation. Its stainless steel outer jacket protects it from heat and wear, extending its lifespan.
