The installation of the thermocouple terminal blocks thermocouple used in the correct installation allows the thermocouple efficient measurement accuracy and more accurate, and installation mistakes could lead to errors in the thermocouple measurements, and evencause the thermocouple damage. The McNair expert analysis thermocouple installation should follow the following requirements.

(a) first measuring thermocouple and the thermal resistance of the size of the thread, thread seat car.

(b) holes in the pipe to be measured according to the diameter of the threaded seat.

(c) threaded seat welding. thread seat insert has a good hole, thread seat and the measurement of pipe welding.

(d) thermocouple or RTD precession welding a good thread.

(e) in accordance with the wiring diagram of the thermocouple or RTD junction box pre-wired and connected with the dial corresponding to the display instrument. Note that the junction box is not in contact with the wall of the measured medium pipes, wiring compartment temperature does not exceed the range of 0-100 ℃. Junction box outlet hole should be facing down the installation to prevent deposition caused due to poor sealing, water vapor, dust and other terminal blocks short circuit.

(f) the location of the thermocouple terminal blocks installed, you should consider the repair and maintenance convenience.
