Pressure Sensor
HDTech Filtration Provides different kinds of Pressure Sensor for Filter assembly.
HDTech HMDT series differential pressure indicators signal the need for filter element change by sensing the differential pressure between ports upstream and downstream of the filter element . They connect to the DeltadyneTM device port available on HDTech filter housings.
