DP Transmitter

Differential Pressure (DP) Transmitter is a highly used industrial instrument that measures the difference in pressure between two points and converts it into an electrical signal. This data is then used to monitor, control, or record pressure in different systems. In Bangladesh, DP transmitters are widely applied in oil & gas, pharmaceuticals, food & beverage, textiles, power plants, and water treatment industries where accurate pressure monitoring is essential for safety and efficiency.

What is a DP transmitter?

A DP transmitter measures the pressure difference between two input ports. The transmitter then sends the measurement as a standard electrical signal (such as 4–20mA or digital output) to a control system (PLC, DCS, or SCADA). It is commonly used to calculate:

• Flow rate (using an orifice plate, venturi tube, or flow nozzle).

• Level measurement in pressurized tanks.

• Filter monitoring (detecting clogging or pressure drop).

• Pressure difference across pipelines or systems.

Key Features of DP Transmitters

• High accuracy and stability.

• Suitable for harsh industrial environments.

• Available in analog and digital versions.

• Can measure flow, level, and pressure differences.

• Easy integration with modern automation systems.

Applications in Bangladesh

DP transmitters are widely used across various industries:

• Oil & Gas – Monitoring pipelines, filters, and tanks.

• Pharmaceuticals – Ensuring cleanroom pressure control.

• Food & Beverage – Process monitoring and quality assurance.

• Textile Industry – Controlling steam and compressed air.

• Power Plants – Boiler and turbine monitoring.

• Water Treatment Plants – Monitoring filter pressure drops and pump efficiency.
