XACT i Process pressure transmitter with flush diaphragm


The XACT i Process pressure transmitter has been developed and won awards for the unique design and practicle use in process applications. Pressure ranges start from 400mbar and go up to 40 bar in either Gauge or Absolute. The pressure transmitter can also be down ranged up to 10 times via the digitally compentsated electronics. ATEX version & HART Communication is optional.

Our piezoresistive silicon sensor DSP 111 is the basis for our x|act i. The sensor is – together with digital compensation electronics – directly mounted into the pressure port, and is connected to the intelligent display and operating module via a I2C-interface of the compensation electronics. With the help of this innovative housing concept, precise and long-term stable pressure transmitters with flush-welded diaphragm and low thermal error can be produced.

The precise pressure transmitter x|act i has been especially designed for the food industry, pharmacy and biotechnology and measures vacuum, gauge and absolute pressure of gases, steam and fluids up to 40 bar. Several process connections e.g. thread or hygienic versions like Varivent®, dairy pipe and Clamp with a flush welded diaphragm are available, which can be combined with a cooling element for media temperatures up to 300 °C. The robust stainless steel globe housing has a high ingress protection IP 67 and all characteristics for a residue-free and antibacterial cleaning.
