A Differential Pressure Transmitter (DP Transmitter) is an industrial instrument designed to measure the pressure difference between two points within a process system. The measured differential pressure is converted into a standard electrical output signal such as 4–20 mA, 0–10 V, or digital communication protocols including HART and RS485. These signals are transmitted to industrial control systems such as PLC, DCS, and SCADA for monitoring, automation, and process control.
Differential Pressure Transmitters are widely used in industrial applications requiring precise measurement of flow rate, liquid level, and differential pressure. Their high accuracy, excellent stability, and reliable performance make them suitable for industries including oil & gas, chemical processing, power generation, water treatment, pharmaceuticals, food & beverage, and manufacturing.
