Chamber Thermocouple (#2, middle jack) - Installation
The purpose of the chamber thermocouple is to measure the temperature of the space between the firing chamber walls and the salt pot. It’s not
intended to be inserted into the salt bath. Generally, the chamber thermocouple is allowed to make contact with the salt pot or is positioned fairly close to
it but no more than a 1/2” away. In this regard, it’s movable.
The Chamber thermocouple consists of two items: Type K thermocouple, 8” long, 1/8” diameter Inconel sheath assembly and a 30”, Type K lead assembly.
Both assemblies are supplied with standard sized male and female connectors.
Note the grounding wire connector on the thermocouple assembly and the green grounding wire included with the lead assembly.
