8 tips for using armored thermocouples

As a temperature measurement sensor, armored thermocouples are usually used in conjunction with temperature transmitters, regulators and display instruments to form a process control system to directly measure or control the temperature of fluids, steam and gas media and solid surfaces in the range of 0-1800℃ in various production processes. Armored thermocouples have many advantages such as flexibility, high pressure resistance, fast thermal response time and durability. Like industrial assembled thermocouples, they are usually used in conjunction with display instruments, recording instruments and electronic regulators as sensors for measuring temperature. There are actually many techniques for using armored thermocouples. Let me talk about them below.

1. Armored thermocouples have bendable properties. Except for the head, armored thermal resistors can be bent in any direction. Therefore, they are suitable for the temperature of small equipment with complex structures.

2. Armored thermocouples have good vibration and impact resistance. Therefore, its thermal resistor life is longer than that of ordinary thermal resistors. When using thermal resistors, pay attention to the following matters.

3. The armored thermocouple has a long service life. The resistor body of the armored thermal resistor is protected by the twist cover and metal sleeve of the ferrite insulation material, and the thermal resistor wire is not easily corroded by harmful media.

4. The explosion-proof thermal resistor uses a specially constructed junction box to confine the explosion of the explosive mixed gas inside its shell due to sparks or arcs.

5. The production site will not cause an explosion. The flameproof thermal resistor can be used for temperature measurement in places with explosion risks in Bla--B3c grade areas. Anti-corrosion thermal resistor 5) The anti-corrosion thermal resistor uses PTFE anti-corrosion material.

6. As an integral protective sleeve or a two-section sleeve, the material can also be directly treated with anti-corrosion treatment, which is divided into three methods: spraying, sintering and sleeve sealing.

7. It is suitable for measurement in corrosive media of strong alkali, with a temperature resistance of 250℃, and the fixed installation form can also use fixed threads of the same PTFE material.

8. According to the measurement temperature range and measurement object, select the appropriate model, specification and protective tube material of the thermal resistor.
