ATEX Sensor
The FL-Wapp ATEX Sensor
The FL-WAPP ATEX Sensor is designed for moisture measurement in potentially explosive dust atmospheres. The measuring head is certified for ATEX Zone 20, while the mounting housing is certified for ATEX Zone 22.
It combines proven FL-WAPP measurement technology with the requirements of explosion protection and enables reliable moisture measurement directly during the ongoing process. This makes the sensor particularly suitable for applications where process safety, precise measurement values, and a robust design are equally important.
Areas of Application
Moisture measurement technology with universal application possibilities in dust explosion hazardous areas. The moisture sensor is ideally suited for process optimization in the chemical, pharmaceutical, food, and animal feed industries.
- In silos
- On dosing belts
- On vibrating conveyors
- In mixers
