SIEMENS Pressure transmitter SITRANS P300

The digital transmitter with HART or PROFIBUS PA communication and stainless steel housing. For the special requirements in the food, pharmaceuticals and biotechnology industry.


The SITRANS P 300 offers the measuring precision and ruggedness already known from the SITRANS P DSIII.

Its stainless steel housing with laser-printed nameplate, together with a wide range of hygienic process connections, mean that it is highly suitable for use in the food & beverages industry as well as for pharmaceutical processes.
With a maximum deviation in measurement of 0.075% and the proven operating philosophy, it fits seamlessly into the SITRANS P family.

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.
