Armored Thermocouple WREK2-294

Short Description:

Armored Thermocouple WRNK2-294 can measure temperatures up to 1000 ℃. The thermocouple WRNK2-294 consists of two different conductors/metals A and B, forming a loop. When the measured temperature change, a thermoelectric electromotive force is generated in the circuit, it will form a thermal current, which is called the thermoelectric effect. Its wiring method is a dual wire thermocouple, which is one of the commonly used temperature detection components in industry.

Product Detail

The armored thermocouple WREK2-294 has the characteristics of bending, high temperature resistance, fast thermal response time, and durability. It is similar to industrial assembled thermocouples as a sensor for measuring temperature, usually used in conjunction with display instruments, recording instruments, and electronic regulators. At the same time, it can also be used as a temperature sensing element for assembled thermocouples. It can directly measure liquids in the range of 0 ℃ to 1000 ℃ in various production processes The temperature of steam, gas medium, and solid surface should comply with the GB/T18404-2001 standard.

Working principle

1. The working principle of armored thermocouple WRNK2-294 is that two different components of conductors are welded at both ends to form a circuit. The direct temperature measurement end is called the measurement end, and the wiring end is called the reference end. When there is a temperature difference between the measurement end and the reference end, thermal current will be generated in the circuit. When connected to a display instrument, the instrument will indicate the corresponding temperature value of the thermoelectric electromotive force generated by the thermocouple.

2. The thermoelectric electromotive force of the armored thermocouple WRNK2-294 will increase with the increase of temperature at the measuring end. The magnitude of the thermoelectric electromotive force is only related to the material of the armored thermocouple conductor and the temperature difference at both ends, and is not related to the length or diameter of the thermocouple.

3. The structure of the armored thermocouple WRNK2-294 is made of conductors, insulated magnesium oxide, and 1Cr18Ni9Ti stainless steel protective tubes that have been repeatedly drawn. The armored thermocouple product mainly consists of a basic structure consisting of a junction box, terminal blocks, and armored thermocouple, and is equipped with various installation and fixing devices.
