Description
The York S1-Q340A1090 36″ Thermocouple 30MV 0.02 OHM is a temperature-sensing component used to monitor pilot flame conditions within gas-fired heating equipment in HVAC systems. It operates by generating a small electrical signal when exposed to heat, allowing the system to regulate gas valve operation and maintain controlled burner performance. It is used in furnaces, boilers, and heating units where flame detection is necessary for safe operation. It works as an essential part within the safety control assembly, supporting stable operating conditions, regulated fuel control, and efficient system performance.
