Immersion Thermocouple (#3, upper jack) - Installation
The purpose of the Immersion thermocouple is to measure the temperature of the salt bath itself. That is to say that the immersion thermocouple is
immersed into the molten salts during operation. It is the Immersion thermocouple that you should use when performing your heat treating as it gives the
actual temperature of the salt bath. The Immersion thermocouple is supplied with a mount.
The Immersion thermocouple consists of two items: Type K thermocouple, (13.75” long on SB 709 and 18” long on SB 718 and SB 818), 3/16” 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.
The immersion thermocouple is also supplied with thermocouple mount. The thermocouple mount properly places the immersion thermocouple within
the pot and away from the pot wall. The thermocouple mount is designed to be easily removable from the pot lip.
