Pump protection with differential pressure

Detect blocked filters and dry running before the pump pays for it.

Oil & Gas

Power & Energy

RECOMMENDED APPROACH

How it is solved

A differential pressure transmitter across the strainer or pump reveals blockage and dry running early, before bearings and seals pay the price.

RECOMMENDED PRINCIPLE

Capacitive differential pressure

Two process pressures deflect a sensing diaphragm between capacitor plates; the capacitance change is proportional to the pressure difference.

TYPICAL LOOP

How the measurement fits the process

Instruments sit on the equipment they protect, send their signal to the controller and act through the final element. Demonstration drawing, not a design.
