MP Filtri can supply indicators of the following designs:
Vacuum switches and gauges
Pressure switches and gauges
Differential pressure indicators
These type of devices can be provided with warning signals visual, electrical or both signals.

Filter elements are efficient only if their Dirt Holding Capacity is fully exploited.
This is achieved by using filter housings equipped with clogging indicators.
These devices trip when the clogging of the filter element causes an increase in pressure drop across the filter element.
The indicator is set to alarm before the element becomes fully clogged.
