DP Transmitter

A Differential Pressure (DP) Transmitter is an intelligent field instrument that measures the pressure difference between two process points and converts it into a standard output signal such as 4–20 mA or RS485 Modbus RTU. It is widely used for flow measurement (with primary elements like orifice plates, venturi tubes, and flow nozzles), tank level measurement, and filter monitoring across various industrial processes. DP transmitters provide high accuracy, long-term stability, and reliable performance in demanding applications.
