Siemens pressure transmitter's advanced principle and structure

Introduction to principle and structure of Siemens pressure transmitter

Siemens pressure transmitter SITRANS P differential pressure series adopts silicon sensor of Siemens patented technology. The modular dsiii series and P310 series are composed of sensor unit with EEPROM, local button with magnetic induction and electronic module of EEPROM. The sensor unit includes pressure sensor and temperature sensor. The pressure sensor and temperature sensor fully compensate the static pressure characteristics and temperature characteristics in the full range respectively, so that dsiii series and P310 series have very excellent static pressure characteristics and temperature characteristics.

SITRANS P Series Intelligent Siemens pressure transmitter is structurally equipped with independent measurement sensor components and unique central anti overload diaphragm that does not play a role in measurement. When the transmitter is subjected to excessive unidirectional load, the measuring diaphragm is close to the transmitter body, and the central anti overload diaphragm ensures that the unidirectional pressure cannot act on the measuring sensor assembly, so as to protect the sensor and make the transmitter have excellent unidirectional overload characteristics. This structure overcomes the shortcomings that the central diaphragm of the traditional transmitter is not only a measuring diaphragm, but also an isolation diaphragm between high and low pressure chambers. The central diaphragm of the traditional transmitter is easy to deform, resulting in easy zero drift of the transmitter and poor long-term stability.

SITRANS P series differential pressure / Siemens pressure transmitter, which integrates long-term successful experience in pressure sensor design and manufacturing and strong electronic debugging and R & D strength, has become an indisputable new industry standard with its stable and reliable performance, first-class quality and simple and convenient use. SITRANS P series differential pressure / pressure transmitter, including dsiii series intelligent differential pressure / pressure transmitter, P300 series Siemens pressure transmitter, P280 series wireless Hart pressure transmitter, p2xx series simple pressure transmitter and MPs series input liquid level transmitter. In addition to the above basic products for measuring differential pressure, pressure, absolute pressure and other process parameters, SITRANS P also includes flange type liquid level transmitter, remote differential pressure transmitter with capillary and remote pressure transmitter. In addition, Siemens also provides corresponding accessories for installation, commissioning and maintenance, including various valve groups, Adapter and SIMATIC PDM field instrument management software, etc.
