Autoclave thermocouples are designed to withstand the harsh environment of an autoclave. They are ideally suited for food appliations where steam washdown is necessary.
A thermocouple probe for use in an autoclave has two conductive wires spaced apart and supported in parallel relation by fluoropolymer insulation material. The structure is air-tight which eliminates vacuum and/or steam leakage along the wire and is relatively flat so as not to disrupt the seal where the thermocouple passes through the autoclave.
