Precautions to be taken when using compensation wires in conjunction with thermocouples

According to the performance and structural methods of thermocouples, they can be divided into special purpose thermocouples such as detachable thermocouples, explosion-proof thermocouples, armored thermocouples, and pressure spring fixed thermocouples.

Wire type thermocouple [detailed description]

1. Characteristics of compensating wire type armored thermistor

Less thermal response time, reducing dynamic errors;

Small diameter, unlimited length;

High measurement accuracy;

Imported thin film resistor components with reliable and stable performance;

2. Working principle of compensating wire type armored thermistor

Armored thermistor measures temperature by utilizing the characteristic that the resistance of a substance changes with temperature. When the resistance value changes, the working instrument displays the temperature value corresponding to the resistance value.

What issues should be noted when using compensation wires in conjunction with thermocouples?

(1) Compensation wires must be matched with thermocouples, and different types of thermocouples should use different compensation wires.

(2) When connecting the compensating wire to the thermocouple, the positive pole should be connected to the positive pole, and the negative pole should be connected to the negative pole.

(3) The two contacts connecting the compensating wire and the thermocouple must be at the same temperature.
