Explosion protection for indicators, load cells and weighing platforms
Explosion protection for:
- RHEWA indicators through the use of zener barriers for legal-for-trade and non-trade applications in Zone 1 and 2. The indicator is outside the ex zone in this case.
- RHEWA indicator with intrinsically safe design, so the entire weighing instrument (indicator and weighing platform) is in the ex zone
- Load cells/weighing platforms with intrinsically safe design (Eex ia IIC T4) for Zone 0, 1 and 2.
We are happy to create the optimum solution for your application!
The following requirements are to be clarified when operating Ex scales:
- Explosion protection zone/temperature class
- Trade approved/non-trade approved application
- Location of the individual scale components (is the entire weighing instrument in the explosion zone or just the weighing platform?)
- Indicator functions (switching, printing, data communications, etc.)
