Explosion-proof thermocouple applications and features1

Instrumentation explosion-proof thermocouple can control the temperature of the object parameter into electrical signal, passed to the display, record and adjusting device, the system testing, adjusting and control. Today mainly introduce instruments explosion-proof thermocouple application and characteristics of the hope can help to you.

explosion-proof thermocouple used

flame-proof thermocouple used in industry is a kind of temperature sensor, a wide application in the chemical industry control system. In chemical plant, the production site is often accompanied by various kinds of flammable, explosive chemical gas, steam, if use common thermocouples are not safe, easy to environment caused by gas explosion. On these occasions, therefore, must use the flame-proof thermocouple temperature sensor.

flame-proof thermocouple used usually and display meter, recording meter, electronic computer and other systems. Directly measuring the production site exist hydrocarbon explosives range of 0 ℃ ~ 1300 ℃ liquid, steam and gas medium, as well as solid surface temperature. Characteristics: a variety of explosion-proof, explosion-proof performance is good; Compression spring type thermal components, ant-vibration performance is good. Measuring range is large; High mechanical strength, good compression performance; Working principle of the explosion-proof thermocouple flame-proof principle is to use the clearance, design has enough strength of the junction box, and other components, all which sparks, solitary and dangerous temperature parts are sealed in the box.

explosion-proof thermocouple features:

a variety of forms of explosion-proof, explosion-proof performance is good.

pressure reed temperature sensing element, ant-vibration performance is good.

temperature measurement range is large;
