Pressure Transmitter  

The SITRANS P500 is a digital pressure transmitter for the measurement of differential pressure, level and flow with highest accuracy. It guarantees a characteristic curve deviation of ≤ 0.03 % as well as outstanding values for the influence of static pressure and temperature on the measured result. The high long-term stability of the sensor reduces maintenance costs thanks to extended calibration intervals, and ensures a high reliability on the measured results long term.

  • Improved control of your systems due to extremely short step response time.

  • Direct-connected use in process temperatures of up to 125 °C (257 °F) even without a remote seal system.
  • High degree of user-friendliness via a 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.  
  • 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.
  • Extensive diagnostics such as 8 min/max pointers for process values showing also the time of the event.
