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.

  1. Improved control of your systems due to extremely short step response time.
  2. Direct-connected use in process temperatures of up to 125 °C (257 °F) even without a remote seal system.
  3. 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.
  4. 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.
  5. Extensive diagnostics such as 8 min/max pointers for process values showing also the time of the event.
