MINERAL INSULATED THERMOCOUPLES AND RTD’S
MINERAL INSULATED TRANSITIONS
Due to the varying size of connection wire and cable, a transition tting is used between the cold end of the sheath and the connecting wires. This tting measures 1-1/4˝ long
by 1/4˝ OD for 1/8˝ or smaller sheaths, and 1-1/2˝ long by 3/8˝ OD for 3/16˝ and 1/4˝ sheaths. Larger sheaths and sheaths terminating in connectors other than wire or cable do
not require transition ttings.
