Differential Pressure Sensor for Filters Model PMP
Description
The PMP differential pressure sensor is used for controlling
and measuring the differential pressure of air or non-corrosive
gases. It is widely used for monitoring filters by measuring
the pressure difference before and after the filter chamber.
The need for a cleaning cycle can then be determined by
the increased differential pressure which activates the
programmable relay. The second relay produces an alarm if
the differential pressure continues to increase. The differential
pressure is shown on a four-digit display. For remote
transmission, a 4- 20 mA output signal is provided. The
device is controlled by a micro processor. Relay, hysteresis,
time delay of the relays, and analog output are programmable.
