Explosion proof safety electronic platform scale3Explosion proof mode selection

1Intrinsic safety: All components of electronic scales are equipped with intrinsic safety explosion-proof measures, suitable for the vast majority of explosive environments.

2. Explosion proof type: Explosion proof boxes are used for certain components of electronic weighing instruments, but components and interfaces outside the explosion-proof box require intrinsic safety treatment.

3. Composite type: All components of the electronic weighing instrument are partially placed in the hazardous area and partially placed in the safe area. Generally, sensors, junction boxes, etc. in the hazardous area are of intrinsic safety type, and then connected to ordinary instruments through associated equipment in the safe area. This mode is quite flexible in configuration because the operation is in a safe zone.

application
Explosion proof electronic scales, explosion-proof platform scales, explosion-proof weighing systems, etc. can be connected to PLC or DCS systems.
