Say all
The industry uses to separate to explode hot electric resistance as temperature to measure and controls of spread the feeling machine and manifestation the gauge kit, with direct measure and control the air,liquid within production line and the temperature of the steam.
The chemical engineering appropriation that my factory produce separates to explode flameproof function of thermocouple,hot electric resistance product to press"the explosion environment use a flameproof electric appliances equipments" of the national promulgation a standard design manufacturing, the hot electricity characteristic matches international IEC standard, and is qualified through the national instrument gauge flameproof safe direct station test.
Separate to explode thermocouple, the structure,principle of the hot electric resistance and assemble a basic homology of way, the main differentiation separates to explode a product to connect the line box(outer shell) to adopt the high strength aluminum metal alloy to die-casting but become on the design, and have enough internal space, the wall is thick with the machine strength, the rubber seals completely the hot stability of the turn to all match national flameproof standard.So while connecting the line box the explosion of the inner part a mixture the air occurrence an explosion, it will not break to connect the line box, but produce from here inside press of the heat can spread outwardly-spread to explode.As long as the customer obeys the product usage rule strictly, the product can attain dependable flameproof result.
Characteristics
Press the type feeling component, the anti- flaps function good;
Measure accuracy high;
Need not to compensate to lead line, save expenses;
Import the thin film electric resistance component, the function credibility stability.
The work principle
The flameproof hot electric resistance makes use of cleft to separate to explode principle, designing to have enough strength to connect the line box an etc. parts, all will produce spark, give or get an electric shock the and zero partses of the dangerous temperature to all seal completely in connect the line box the , be When the occurrence in the explode, can pass coalescence the noodles cleft to turn off with the cooling, make the flames and temperature of explode the empress could not spread the outside of the , Be thus carry on separating to explode.
Main technique parameter
The product performance standard
IEC751
JB/T18622-1997
JB/T8623-1997
JB/T5518-91
The normal temperature insulates electric resistance
The hot electric resistance is 15-35 ° Cs in the environment temperature, the relative humidity is no bigger than 80%, experimenting electric voltage to insulate electric resistance for of the 10-100 Vs(direct current) electrode and the coat tube>100 M Ω .
