PMP - Differential Pressure Sensor for Filters

Brand: KOBOLD Instruments, Inc

The PMP differential pressure sensor is used for controlling and measuring the differential pressure of low pressure 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.
