Process Clogging Indicators




Process clogging indicators
HYDAC clogging indicators are designed to indicate visually and/or electrically when the filter elements must be changed or cleaned. Differential pressure indicators are used on all process filters. They react to the pressure differential between the filter inlet and the filter outlet, which rises as the level of contamination in the filter element increases.
- Differential pressure indicators
- Visual, electrical or analogue differential pressure signal
- Wide range of pressure settings
- Optional electrical ATEX indicator
