Frequently Asked Questions

What is a Differential Pressure Transmitter Used For?

A differential pressure transmitter measures the pressure difference between two points for applications such as flow measurement, liquid level monitoring, filter condition monitoring, and industrial process control.

What is the Difference Between a Pressure Transmitter and a Differential Pressure Transmitter?

A pressure transmitter measures pressure relative to atmospheric or vacuum pressure, while a differential pressure transmitter measures the difference between two independent pressure points.

Can Differential Pressure Transmitters Measure Tank Level?

Yes. They are commonly used to measure liquid levels in closed or pressurized tanks by detecting hydrostatic pressure differences.

What Output Signals are Available?

Depending on the model, differential pressure transmitters support 4–20mA, HART, and other industrial communication protocols.
