Product Description

WZP-641 fabricated thermal resistance

Brief Description

Industrial explosion-proof platinum resistor is a temperature sensor which is widely used in industrial automatic control systems. It can switch the object’s temperature parameter into signals and send it to displayer, recorder and regulator. It is used to test, adjust and control the system.

If we use an ordinary platinum resistor in the chemical plant which often accompanied by a variety of explosive, flammable and other chemical gases, vapors, it is very easy to cause the environment gas explosion. Therefore, we must use explosion-proof resistance thermometer on these occasions. Our explosion-proof resistance thermometer is suitable to occasions with explosive gas where the temperature group is between dIIBT4~dIICT6.
