PI2098 IFM Pressure Sensor – PI-,25BRES30-MFRKG/US/ /P

The IFM PI2098 is a high-precision ceramic-capacitive pressure sensor designed for hygienic applications in the food and beverage industry. Offering a flush mountable Aseptoflex process connection, the sensor delivers reliable measurement of relative pressure from –12.4 to 250 mbar, with robust protection against overload (6000 mbar) and exceptional long-term stability. The PI2098 features a rotatable housing, dual output (1x digital + 1x analogue), and gold-plated M12 contacts, ensuring performance in demanding, media-rich environments. With IP69K protection and intelligent parameterization, it meets the highest standards for clean-in-place and high-temperature processes.
