Transmitters for gauge and absolute pressure for food, pharmaceuticals and biotechnology

SITRANS P300

Digital pressure transmitter with a stainless steel housing and LCD display. Communication is over HART, PROFIBUS PA or FOUNDATION Fieldbus interface. Various hygiene-based connections and flange connections with front-flush diaphragms meet the requirements of a dead space free process connection.
Just like the SITRANS P DS III, the SITRANS P300 stands for precise measuring and ruggedness, and especially for an innovative operating concept. With the SITRANS P300, these time-proven features are now also available for processes in the food & beverage and pharmaceutical industries.

With a maximum error of measurement of 0.075 %, a hygienic stainless steel housing with laser-inscribed rating plate, and the time-proven SITRANS P DS III operating philosophy, it fits in perfectly with the SITRANS P product range.

SITRANS P300 features:
  • Measurement cells for gauge and absolute pressure
  • Measurement cells with flush mounted diaphragm
  • extended simulations and diagnostic functions
  • Measurement deviation ≤ 0,075%
  • Long term stability ≤ 0.25% / 60 months
  • Specified teperature range up to 392oF (200oC)
Parameters can easy set via three local push buttons and LCD display, HART or PROFIBUS PA profile 3.0 communication.
