Description
A differential pressure (DP) transmitter is a device that measures the difference between two pressures in a system, sending this measurement as an electrical signal (typically 4-20 mA) to a control system. It works by comparing the high-side and low-side pressures using internal diaphragms, which deflect to create a signal proportional to the pressure difference. DP transmitters are crucial in industrial applications for monitoring flow, liquid level, and filter condition by measuring the pressure drop across components
