SITRANS P250 is a fixed range transmitter for differential pressure. The differential pressure would be detected with a ceramic sensor and transformed into an output signal of 4-20 mA- resp.0-10 V signal.

• Accuracy: ≤ 1 %
• Long Term Stability: ≤ 0.5 % /12 Months
• Measuring Range: 0 - 100 mbar to 0 - 25 bar

• Connection and housing of high-grade steel 1.4305
• Ceramic diaphragm

The SITRANS P DS III series includes digital pressure transmitters for measuring gauge pressure, absolute pressure, differential pressure, flow and level. 
Even the standard devices offer comprehensive diagnostics and simulation functions with high reliability. The suitability for use in SIL2 circuits has been certified by external test institutes. 
With Profibus transmitters, the new PROFISAFE technology guarantees uniform safety from the control system down to the transmitter.

• Accuracy: ≤ 0.075%
• Long Term Stability: ≤ 0.25% / 60 Months
• Measuring Range: 0 - 10 mbar to 0 - 400 bar 

• Extensive diagnostics and simulation functions
• Suitable for installation in SIL 2 applications in accordance with IEC 61508 /IEC 61511. In the PROFISAFE version, it guaranteess maximum communication safety up to the control system level
• Wide range of certification and approval e.g. ATEX EEx ia, EEx ib, Dust protection, FM, CS
• Option of using a simulation function for loop check functions
• Opens up a host of different bus communication options for you: HART, PROFIBUS PA, PROFIsafe or FF

The SITRANS P500 has been developed to meet the highest expectations for measuring accuracy, ruggedness, and user-friendliness, and it merges seamlessly into the SITRANS P family. With the SITRANS P500, you can expect pressure measurement at the highest level.

It guarantees an accuracy of ≤ 0.03 % as well as outstanding values for the influence of static pressure and temperature on the measured result. In this way, it guarantees a total performance of ≤ 0.14 % up to a turndown of 10:1. Since this feature means that only one measuring cell can be used for different measuring ranges, inventory costs can be significantly reduced without the need for losses in the quality of the measured result. The high long-term stability of the sensor also reduces maintenance costs thanks to extended calibration intervals, and ensures that you can always rely on the measured results in the long term.

An innovated sensor assembly enables direct-connected use in process temperatures 
of up to 125 °C (257 °F) even without a remote seal system.
