Siemens P 500 Pressure Transmitters

The SITRANS P500 has been developed to meet the highest expectations for measuring accuracy, ruggedness, and user-friendliness.

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. 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.

  • Accuracy: ≤ 0,03 % (for a TurnDown up to 10)
  • Long-term stability: 0.05 % / 5 years
  • Measuring range: 0 – 1,25 mbar bis 0 – 1250 mbar
  • Highest measuring accuracy
  • Outstanding values for the long-term stability
  • Optimized  full-text-enabled, backlit display and 3 pushbuttons. The transmitter can also be configured and operated conveniently from the control system using the HART protocol
  • Extensive diagnostics
  • Process temperature up to 125 °C (257 °F) possible without remote seals
