Thermocouples

Robertshaw® thermocouples are the industry leader for gas heating and appliances. Their primary function is to ensure a standing pilot light is operative so that on a call for heat, the main burner gas will be properly ignited. Thermocouples are placed in gas applications to detect existence of a flame for safety purposes by shutting off the potential gas flow to a burner. The Robertshaw thermocouples are made of two different metals with various lengths. A thermocouple 18 (460mm) long has a lower resistance and higher electrical output compared to a 72 (1830mm) thermocouple which has a higher resistance (longer wire) and, therefore, lower electrical output. The 1900 Series are T-46 thermocouples which have a threaded nut attached and a tinnerman clip included.

The Robertshaw® 1960 Series Thermocouple  is a special low-mass or quick dropout thermocouple. It is usually found on applications that require an oxygen depletion system on the thermo safety. It is also found on many LP gas applications that require a quick dropout of the thermo safety if there is a loss of pilot flame. ATTENTION: The 1960-027 has standard thermocouple threads, and WILL NOT fit applications with metric threads.

The Robertshaw 1970 Series  Thermocouple Uni-Couple ® design allows for installation to virtually all pilot burners. The versatile zip nut may be pushed, pulled or threaded onto the thermocouple's rolled threads for proper positioning in every application.

The Robertshaw® 1980 Series Snap-Fit ® Thermocouples offer easy installation into the majority of pilot burners. They are manufactured without complicated adaptors, but with extra insulation that the brass sheath provides under high ambient temperatures.
