Differential Pressure Transmitter

Differential Pressure Transmitter – Internal Working Explained!

Have you ever wondered how a DP Transmitter measures flow, pressure, or level in industrial processes?

This detailed cross-section view shows the important internal parts of a Differential Pressure Transmitter, including:

High & Low Pressure Side

Differential Pressure Sensor

LCD Display & Electronics

Impulse Lines

Orifice Plate Working Principle

4–20 mA Signal Conversion

Understanding DP transmitters is very important for:

Instrumentation Engineers

Process Engineers

PLC/DCS Technicians

Maintenance & Commissioning Engineers

Engineering Students

In flow measurement, the orifice plate creates a pressure difference, and the DP transmitter converts it into an electrical signal for monitoring and control.
