Tips for using armored thermocouples

Armored thermocouples have many advantages such as being able to bend, withstand high pressure, have fast thermal response time, and are sturdy and durable. Like industrial assembled thermocouples, they are used as sensors for measuring temperature and are usually paired with display instruments, recording instruments, and electronic regulators. At the same time, they can also be used as temperature sensing components for assembled thermocouples. It can directly measure the temperature of liquids, vapors, gas media, and solid surfaces in various production processes from 0 ℃ to 800 ℃. Compared with assembled thermocouples, armored thermocouples have advantages such as bendability, high pressure resistance, short thermal response time, and durability.
There are actually many techniques for using armored thermocouples. Here are eight tips for installing thermocouples:
1. It has bendable performance, and the Kaizhuang thermoelectric resistor can bend in any direction except for the head, making it suitable for complex structures and temperature sensitive small devices.
2. Armored thermocouples have good resistance to vibration and impact. Therefore, its thermoelectric resistance has a longer lifespan than ordinary thermoelectric resistors When using a thermistor, the following precautions should be taken.
3. Armored thermocouples have a long service life. Due to the twisted cover of weighted iron insulation materials and the maintenance of metal sleeves, the resistance body of Kai mounted thermal resistors is not easily corroded by harmful media.
4. Explosion proof thermistors use a special junction box to limit the explosion of explosive mixed gases inside their casing caused by sparks or arcs within the junction box.
5. The production site will not cause excessive explosions. Explosion proof thermal resistance can be used for temperature measurement in explosive hazardous areas within Bla -- B3c level areas. 5) The anti-corrosion thermistor is made of PTFE anti-corrosion material.
6. As an integral protective sleeve or a two-piece sleeve, the material can also be directly applied to the protective tube for anti-corrosion treatment, which can be divided into three forms: spraying, sintering, and sleeve sealing.
7. Suitable for measurement in strong alkaline corrosive media, with a temperature resistance of 250 ℃. The fixed installation situation can also use the same PTFE material for fixed threads.
8. Select the appropriate model, specification, and maintenance tube information for the thermal resistor based on the temperature range and side measurement object.
Armored thermocouples mainly consist of junction boxes, terminal blocks, and armored thermocouple components, and are equipped with various installation and fixing devices. The installation of fixed type fixing devices is for users to use during installation. Armored thermocouples have five structural types: non fixed device, fixed sleeve type, movable sleeve type, fixed flange type, and movable flange type. The fixed sleeve type is only for one-time fixed use, while the movable sleeve type can be used for multiple fixed uses.
