K Type Thermocouple WRN-132 WRN-133 WRN-131

Description

K Type Thermocouple WRN-132 WRN-133 WRN-131 Assembly-type thermocouple without fixed device connection, waterproof type, thermocouple WRN-130 WRN-131 WRN-132 WRN-133 is used as temperature sensor, WRN-133 temperature measurement to do 130 WRN-131 WRN-132 WRN-133 are usually matched with display devices, recording meters and electronic computers. Thermocouple WRN-130 WRN-131 WRN-132 WRN-133 can directly measure the temperature from 0℃ to 1300℃ of liquid, gas medium and solid surface during various manufacturing process. In addition, Thermocouple WRN-130 WRN-131 WRN-132 WRN-133 has the advantages of easy assembly, convenient replacement, pressure spring type temperature sensing element, good anti-vibration, wide measurement range, high mechanical strength, good pressure stability.

K Type Thermocouple WRN-132 WRN-133 WRN-131 Working Principle

Thermocouple WRN-130 WRN-131 WRN-132 WRN-133 Working principle: two conductors with different materials are welded at both ends to form a loop, the temperature measured directly is called the measuring side, the terminal side is called the reference side.

When there is a temperature difference between the reference side and measurement side and the thermocouple WRN-132, WRN-130 WRN-131, WRN-133 will generate heat in the loop current, then connect to the display device, and the device will indicate the corresponding temperature value of the thermal electromotive generated by the thermocouple. The thermocouple measures the thermoelectric EMF as the temperature increases, the magnitude of the thermal electromotive force is proportional to the temperature at both ends. The length of the thermode has nothing to do with the diameter.

The junction box, protective tube, insulated casing, thermal and thermal electrodes form a basic structure of the assembly-type thermocouple with a variety of fixture installations.

When a step change in temperature is observed, the output variation of the thermocouple is equivalent to 50% of the change, the required time is called the thermal response time “T0.5”.
