Product Description

PRINCIPLE

Pressure transmitter is a device that converts pressure into pneumatic signal or electric signal for control and remote transmission. It can convert the physical pressure parameters of gas, liquid, etc. sensed by the load cell sensor into standard electrical signals (such as 4-20mADC, etc.) to provide secondary instruments such as indicator alarms, recorders, regulators, etc. for measurement and indication And process regulation.

FEATURES

The pressure transmitter selects sputtering film sensor, imported silicon diffusion type, ceramic pressure sensor as sensitive components, and adopts a dedicated integrated module. After fine temperature drift, zero point, and nonlinear compensation, it can realize the control of liquid level, gas, and steam. Accurate measurement and transmission of pressure changes of other media. Realize ideal monitoring of pressure vacuum in various places in industrial and mining enterprises, scientific research institutes and other departments.

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.
