Characteristics of prefabricated thermocouples

Prefabricated thermocouple is a type of thermocouple and a commonly used measuring instrument, mainly used to measure the surface temperature of various liquids, gases, vapor media, and solids. Have users experienced the characteristics of prefabricated thermocouples during use? Below, let me introduce the specific features of prefabricated thermocouples.

The thermoelectric potential generated by prefabricated thermocouples is only related to the material of the thermoelectric electrode and the temperature difference between its two ends, and is independent of the length and diameter of the thermoelectric electrode. Usually used in conjunction with display instruments, regulating instruments, recorders, and data collectors. Prefabricated thermocouples have many advantages, such as low component disassembly, easy maintenance, low cost of replacing vulnerable parts, high sensitivity, strong stability, good interchangeability and accuracy for remote transmission of electrical signals. The room temperature insulation resistance of platinum resistance thermometers should not be less than 100M Ω, and the room temperature insulation resistance of copper resistance thermometers should not be less than 50M Ω. Widely used in production sites such as petroleum and chemical industries where various flammable and explosive gases and vapors are present.

Characteristics of prefabricated thermocouples:

1. Simple assembly and easy replacement.

2. Pressure spring type temperature sensing element with good anti vibration performance.

3. The measurement range is large.

4. High mechanical strength and good pressure resistance.
