The use of armoured thermocouple technique

Armoured thermocouple can bend, high pressure resistance, heat fast response time and strong and durable many advantages, such as it and industrial prefabricated thermocouple, as measure temperature sensor, and usually display meter, recording meter and electronic regulator, at the same time, also can be used as a prefabricated thermocouple temperature sensing element. It can directly measure all kinds of production process from 0 ℃ ~ 800 ℃ in the scope of liquid, steam and gas medium, as well as the surface temperature of the solid. Compared with prefabricated thermocouple, armoured thermocouple is flexible, high pressure resistance, thermal response time is short and strong and durable, etc.

use armoured thermocouple, there are a lot of skills. Bottoms thermocouple used eight skills introduces below:

1. With flexible performance, kai thermal resistance in addition to the head, can make the direction of bending, so it is suitable for the structure is relatively complex, DE temperature of small equipment.

2。 Armoured thermocouple has good resistance to vibration and shock resistance. So it's longer than ordinary heat resistance thermal resistor. Thermal resistance should pay attention to when using the following matters.

3。 Armoured thermocouple long using life, kay thermal resistance of the resistor body by iron power twist of insulation materials cover and metal casing maintenance, heat resistance wire is not easy to jung corrosion by harmful medium.

4。 Flameproof thermal resistance through the special structure of the junction box, its shell internal explosive mixed gas by affected by sparks or electric arc explosion limits in the junction box.

5。 That wouldn't make production field explosion. Flameproof thermal resistance can be used in the Bla - B3c level zone with explosion danger place temperature measurement. 5) anticorrosive thermal resistance The anti-corrosion heat resistance using PTFE anti-corrosion material.

6. As a whole case or two casing, also can be directly on the protecting tube for the anti-corrosion material handling, spraying, sintering and casing sealed three forms.

7。 Apply to measure in alkali corrosive medium, heat resistance, 250 ℃, fixed installation situation also can use the same PTFE material fixed screw thread.

8。 Object, according to the measured temperature range and measurement of choosing the proper thermal resistance model, specification and maintenance of pipe materials.

armoured thermocouple is mainly composed of terminal block, terminal and armoured thermocouple elements such as basic structure, and with various mounting device. Installing a fixed type of fixture is for users to install use. Armoured thermocouple are: no fixed device, clamp sleeve type, movable card sleeve, a fixed flange, movable flange five kinds of structure. Fixed card only for the use of disposable fixed set of type, can do many times of cutting sleeve type has the fixed to use.
