WZP explosion-proof thermal resistor WZPK explosion-proof armored thermal resistor

1、 Product Introduction Product introduction

WZPThe series of industrial explosion-proof thermistor is a temperature sensor. It is widely used in industrial automation systems. Through temperature sensors, the temperature parameters of the controlled object can be converted into electrical signals and transmitted to display, record, and regulate instruments to detect, regulate, and control the system.

WZP seriesindustrial flameproof thermal resistance is a kind of temperature sensor. It iswidely used in the industrial automatic control system. Through the temperaturesensor, the temperature parameters of the control object can be changed intoelectrical signals and transmitted to the display, recording and regulatinginstruments to detect, adjust and control the system.

At the production site of chemical plants, various flammable and explosive chemical gases, vapors, etc. are often present. If ordinary thermal resistors are used, it is very unsafe and can easily cause environmental gas explosions. Therefore, explosion-proof thermal resistors must be used as temperature sensors in these situations. The explosion-proof thermistor products produced by our company are suitable fordIIBT4~dIICT6In places with explosive gas hazards within the temperature range.

Productionsite of a chemical plant is often accompanied by various flammable, explosiveand other chemical gases and vapors. If ordinary thermal resistors are used, itis very unsafe, and it is very easy to cause environmental gas explosion. therefore,flameproof thermal resistance must be used as temperature sensor in theseoccasions. the flameproof thermal resistance products produced by the companyare applicable to places with explosive gas hazards within the temperaturegroup of dIIBT4~dIICT6.

2、 Working principle Operational principle

The structure and principle of explosion-proof or intrinsically safe thermal resistors are basically the same as those of assembled thermal resistors, except for the junction box of explosion-proof or intrinsically safe products(shell)In terms of design, a special explosion-proof structure is adopted, and the junction box is made of high-strength aluminum alloy die-casting, with sufficient internal space, wall thickness, and mechanical strength. The thermal stability of the rubber sealing ring meets the national explosion-proof standards. So, when the explosive gas mixture inside the junction box explodes, its internal pressure will not damage the junction box, and the resulting heat energy cannot diffuse outward—Spread the word.

Flameproof Or intrinsically safe Thermalresistance And the assembly type Thermal resistance Structure, The same basicprinciples,The difference is, Flameproof Or intrinsically safe product Junctionbox (shell) In the design of the Explosion proof special structure, Wiring boxfor high strength aluminum alloy die-casting and, And has sufficient internalspace, Wall thickness and mechanical strength, The rubber sealing ring Thermalstability Are in line with national standards for explosion proof. So, When thewiring inside the box Explosive gas mixture When the explosion, The innerpressure Will not damage the junction box, The resulting Heat energy can not beoutward diffusion of detonation.

Due to the use of the above-mentioned explosion-proof special structure, the product fully meets the requirements for use indIIBT4todIICT6TheibBT4TheiaIICT6Within the scope of explosion-proof category, as long as users strictly follow the product usage rules, the product can achieve reliable explosion-proof effect.

Because the product uses Theexplosion-proof special structure, The product fully meets the use in dIIBT4 TodIICT6TheibBT4TheiaIICT6Explosion proof class scope, As long as the user Products in strict compliancewith the rules of use, The product can achieve reliable Explosion proof effect.
