Tempco TTW00065 Type J Thermocouple electrical box

Type J Thermocouple for Industrial Use

This Tempco thermocouple uses a grounded Type J junction to measure temperature in appliances, ductwork, food and beverage lines, HVAC systems, ovens, packaging equipment and pharmaceutical processes. It suits technicians and engineers who need a direct-contact sensor for low-temperature industrial control loops.

Range and Wiring Constraints

The sensor operates from 32 to 1,400 degrees Fahrenheit (0 to 760 degrees Celsius), so it cannot handle cryogenic or ultra-high-temperature environments. Its six-foot bare-wire cable with split leads requires termination at the instrument, and the grounded junction makes it susceptible to electrical noise in unshielded installations.

Simple Mounting with Wiring Care

The 3/16-inch by 6-inch probe fits standard fittings and installs by inserting the sheath into the process connection. The main difficulty is routing the bare leads without strain relief and ensuring the grounded junction does not create a ground loop with the measuring instrument.
