The P131 pressure transmitter is characterized by a front-flush measuring element. Clogging of the membrane is prevented most effectively and can be easily cleaned if necessary. The combination of a ceramic sensor and a front-flush PVDF housing makes the pressure transmitter universally applicable. Due to the material of the O-ring, e.g. FFKM (Chemraz / Kalrez), the sensor is resistant to most aggressive chemicals. The capacitive measuring principle enables a very accurate and long-term stable measurement, even at lowest pressures and high overload resistance. Our modular design concept provides a wide variety of products. Feel free to contact us if you need a customization that is not listed in this datasheet.
