WZP2-44SA Explosion proof RTD

WZP2-44SA Explosion proof RTD

Overview

WZP2-44SA Explosion proof RTD as a temperature sensor, In some places where flammable and explosive gases exist, Explosion-proof RTD must be used to prevent explosion.in the field of automation and control, the temperature signal can be converted into an electrical signal, which is passed to the display, recording and adjustment instruments to detect, adjust and control the system.

Working principle

WZP2-44SA Explosion proof RTD ordinary thermal resistance, Its heated part is evenly wound with a thin metal wire on a skeleton made of insulating material. When there is a temperature gradient in the measured medium, the measured temperature is the average temperature of the medium within the range of the temperature sensing element. is to use the resistance of the substance itself to change with the change of temperature. On this basis, the junction box is made of high-strength aluminum alloy die-casting, which has enough space, thickness and strength. The thermal stability of the rubber sealing ring conforms to the national explosion-proof standard. When the explosive gas inside the junction box explodes, the electric spark inside will not leak to the outside of the junction box.

Features

1, No need for compensation wires, saving costs

2, Temperature sensing element is compression spring type, has good shock resistance

3, High accuracy

4, Thin film resistance element, stable performance
