Pressure Transmitter FAQ

What is a pressure transmitter used for?

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.

How do I choose the right pressure transmitter?

Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.

What is the difference between gauge, absolute and differential pressure transmitters?

Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.

Can Xinyi Instrument provide customized pressure transmitters?

Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
