Differential Pressure Indicator 5.01
The "Robust" for aggressive media
The deltaP® - differential pressure indicators are used to monitor a variable pressure difference by optical indication and electrical contacting in up to two points.

An increasing pressure difference moves a piston against the force of a calibrated measuring spring. The piston position is transmitted to the indicator and/or switching mechanism without contact or friction. The filter contamination and therefore also the differential pressure grows exponentially with time. Thus, at 80% of the max. contamination, already 95% of the filter service life can be reached. This is compensated for by special design of the indicator system.
