The variety of explosion-proof armoured thermocouple classification and flame-proof principle

Commonly used explosion-proof thermocouple and thermal resistance

latest explosion-proof specifications according to IEC international standard GB3836.

double cavity explosion-proof structure, change the temperature component is simple, safe and reliable.

d Mark II BT4, apply to the following II b, ignition temperature T4, including explosive gas temperature measurement.

explosion-proof armoured thermocouple and thermal resistance:

protection tube and measuring unit as a separate structure, rapid temperature changing components, not stop to repair.

protection tube has various forms and materials and can meet the high pressure, high temperature and strong corrosive medium temperature measurement needs.

equipped with armored unit, pressure, seismic, stable and reliable.

tag d II BT4, ia CT4 II applies to secondary, T4 ignition temperature, contain explosive gas temperature measurement.

explosion-proof thermocouple type: k type explosion-proof type explosion-proof wear-resistant thermocouple, thermocouple k e explosion-proof type thermocouple and multipoint, explosion-proof explosion-proof thermocouple thermocouple assembly, more explosion-proof performance, explosion-proof armoured thermocouple armoured thermocouple, thermocouple, explosion-proof explosion-proof, explosion-proof corrosion resistance thermocouple sheathed thermocouples, etc.

if two different components of homogeneous conductor ( Hot electrode) Is a closed loop, at the end, when there is a temperature gradient through the current loop between thermoelectric loop ends ( As shown in the figure below)

the explosion principle:

flame-proof principle, junction box and other parts of the design has the enough strength, will all produce spark, arc and dangerous parts sealed under the temperature inside the box, when the explosion occurred inside the cavity, through joint clearance of stall and cooling, external cavity wasn't up to fire and explosion temperature
