Intrinsically safe explosion-proof

 This product has passed the inspection of the National Explosion-proof Electrical Products Quality Inspection Center and obtained an explosion-proof certificate. When using, please pay attention to the following matters:

The sensor must be powered by an intrinsically safe power supply, otherwise it will affect the explosion-proof performance.

It is prohibited to replace the sensor in a hazardous area.

 It is prohibited to disassemble or replace the sensor element to avoid affecting the explosion-proof performance.

 It is not allowed to replace components or structures to avoid affecting the explosion-proof performance.

 The installation and wiring of the safety barrier must be carried out in accordance with the safety barrier instruction manual, and the safety barrier must obtain an explosion-proof certificate.
