SIEMENS SITRANS Pressure / Differential Pressure Transmitters and Transducers

Siemens offers the SITRANS P pressure transmitter line, a comprehensive range of pressure measuring products designed to be adaptable to the specific requirements of different processes, infrastructures, and ambient conditions. This series provides various performance levels, load capacities, and material ranges to meet diverse needs. The SITRANS P series is known for its precision, robustness, and user-friendly design. Furthermore, these pressure measurement devices comply with industry standards and international certifications, making them well-suited for the increasingly complex tasks of the process industry


The SITRANS P200, P210, and P220 are versatile compact single-range transmitters tailored for measuring absolute and gauge pressure. They make use of two stainless steel sensors (P210 and P220) and one ceramic diaphragm sensor (P200), allowing for the measurement of process, absolute, and hydrostatic pressure. Moreover, the output signal can be optionally converted into a 4-20 mA or 0-10 V signal as per the determined pressure, providing flexibility for a wide range of industrial pressure measurement applications.

The SITRANS P 300 is renowned for its measurement precision and durability, akin to the SITRANS P DSIII, and features a stainless steel housing with a laser-printed nameplate. This, combined with a wide array of hygienic process connections, makes it well-suited for applications in the food & beverages industry and pharmaceutical processes. With a maximum measurement deviation of 0.075% and a proven operating philosophy, it seamlessly integrates into the SITRANS P family.
This digital pressure transmitter caters to both relative and absolute pressure measurements, offering conventional thread versions as well as flush-mounted versions, with many of the latter suitable for food and pharmaceutical applications, meeting EHEDG and 3A hygiene requirements.
The output signal is a load-independent direct current from 4 to 20 mA or a PROFIBUS PA or FOUNDATION Fieldbus signal, linearly proportional to the input pressure. Communication is achieved via HART protocol or PROFIBUS PA or FOUNDATION Fieldbus interface, and basic settings can be easily configured on-site using three buttons.
Encased in a single-chamber stainless steel enclosure, the pressure transmitter is approved for "intrinsically safe" type of protection and can be utilized in zone 1 or zone 0 hazardous areas.
