Product Description

Product Description

Siemens Differential Pressure Transmitter

Siemens pressure transmitter SITRANS P differential pressure series adopts silicon material sensor of Siemens patent  technology. The modular design of DSIII series and P310 series consists of sensor unit with EEPROM and electronic  module with magnetic induction on-site button and EEPROM. The sensor unit includes a pressure sensor and a temperature  sensor, which fully compensate the static pressure characteristics and temperature characteristics in the full range  respectively through the pressure sensor and temperature sensor, so that the DSIII series and P310 series have very  excellent static pressure characteristics and temperature characteristics.


SITRANS P series intelligent Siemens pressure transmitters have independent measurement sensor components and a unique  central anti-overload diaphragm that does not measure. When the transmitter is subjected to an excessive one-way load,  the measuring diaphragm is tightly attached to the transmitter body, and the central anti-overload diaphragm ensures  that the one-way pressure cannot act on the measuring sensor components, thereby protecting the sensor and making the  transmitter Has excellent one-way overload characteristics.

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.
