  • A thermocouple senses temperature at a pilot burner. The thermocouple determines if the main flame is hot and safe enough to ignite natural gas or propane to the burner. A thermocouple consists of two different metals joined together at one end. This unique bond of metals produces a small voltage at a given temperature.

    Honeywell, the leading manufacturer in thermocouples, produces a standard thermocouple as well as a thermocouple with maximum copel. Copel is an alloy of copper and nickel. A thermocouple with a higher amount of copel will have a longer life span than a standard thermocouple. Honeywell thermocouples are available in lengths of 18", 24", 30", 36", and 48".

    Robertshaw is known for its Uni-Couple thermocouple Series. The unique design of the Uni-Couple allows for installation to almost all pilot burners. The design includes a stainless steel tip which provides longer life, copper tubing for corrosion protection and low electrical resistance, and an extended cold junction for greater voltage output. Uni-Couples are available in lengths of 18", 24", 30", 36", 48", 60" and 72" making them an extremely versatile option.

    The Snap-Fit Thermocouple is an additional series of thermocouples by Robertshaw. Thermocouples in this series don't need complicated adapters to adapt to most pilot burners, making installation simple. Snap-Fit Thermocouples are available in lengths of 12", 18", 24", 30", 36", 48", 60" and 72".

    A thermopile generator consists of multiple thermocouples linked in a series to increase millivoltage output. Sufficient power is generated and can operate an automatic millivolt gas control system, independent from any exterior power source. Thermopile generators are available in a variety of lead lengths and connection types, making them cost effective and resourceful.
