What is the _ instrument thermocouple installation and use

Thermocouple should avoid too close to or from the heating body installed on the stove, should try to install where no vibration or vibration is very small, at the same time to facilitate the construction and maintenance. Installation position should be kept vertical, but must be installed tilt at a velocity. Junction box out of the hole should be down. Thermocouple should be in accordance with the provisions, wiring, usually use three wire system. Connecting wires should be insulated copper wire, the cross-sectional area shall be 1 or more. 0 square millimeter, the resistance of the wire shall be according to the provisions of the digital display table. By thermal inertia thermocouple lags behind temperature changes, to eliminate the error due to its, should as far as possible to reduce the thermocouple protection tube diameter, increasing thermocouple insertion depth increase thermocouple heated parts. Always check the protection tube, immediate measures should be taken to find the oxidation or deformation, check regularly.
