Pressure Measurement

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.

Accuracy ≤ ۰,۰۳ % (for a TurnDown up to 10)
Long-term stability 0.05 % / 5 years
Measuring range 0 – ۱,۲۵ mbar bis 0 – ۱۲۵۰ mbar

It guarantees an accuracy of ≤ ۰.۰۳ % 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 ≤ ۰.۱۴ % 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. With an improved 3-pushbutton operator input concept for setting the device, the SITRANS P500‘s host of diagnostics options can be used conveniently without software.

Even curve displays and trend diagrams can be represented on the display for user-friendly process monitoring.

Pressure Measurement

The SITRANS P DSIII 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.
