SIT’ Style Thermocouple 750mm

This 750mm SIT-style thermocouple is a reliable flame-failure safety sensor designed to work with SIT-type gas valves, including Honeywell, Junkers, ITT and Robertshaw. When heated by the pilot flame it generates a millivolt signal to keep the gas valve open; if the flame goes out, the signal drops and the gas supply is shut off automatically. With a 750mm length and M10 fitting, it’s a dependable, easy-fit replacement for gas fires, boilers and commercial catering equipment.
