The IFM PI2204 is a flush pressure sensor with display designed for hygienic pressure measurement in food and beverage applications. It measures relative pressure and vacuum from -1 to 10 bar and supports liquids, gases, viscous media, and liquids containing suspended particles. Two digital outputs, a scalable 4…20 mA analogue output, and IO-Link provide flexible automation connectivity. Its DN40 Clamp process connection and flush design support hygienic installation with low dead-space characteristics. The sensor can operate with medium temperatures up to 200 °C under specified ambient conditions.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The PI2204 is designed for flush installation in hygienic process systems. Its DN40 Clamp connection follows DIN 32676/ISO 2852. The -1…10 bar range allows both vacuum and positive-pressure monitoring. It can handle viscous media and liquids containing suspended particles. This makes it suitable for food, beverage, and process applications.
The PI2204 supports medium temperatures from -20…200 °C, with restrictions when measuring negative pressure. At medium temperatures up to 200 °C, the ambient temperature is limited to -25…65 °C. The pressure rating is 50 bar and the minimum burst pressure is 100 bar. IP67/IP68/IP69K protection provides strong resistance against demanding process environments. These characteristics make the sensor suitable for high-temperature process equipment.
The PI2204 provides two digital outputs and one scalable 4…20 mA analogue output. The digital outputs can be configured as normally open or normally closed. IO-Link communication operates through COM2 at 38.4 kBaud. The minimum IO-Link process cycle time is 2.3 ms. These interfaces provide both conventional PLC connectivity and digital sensor integration.

The PI2204 uses stainless-steel 316L/1.4435 wetted construction. Its wetted surface has a specified Ra <0.38 µm finish. The flush design helps minimise product accumulation at the pressure measuring point. The pressure transmission fill fluid is NEOBEE food-grade and FDA compliant. These features support hygienic process requirements.
Install the PI2204 using a compatible DN40 Clamp connection. Ensure the hygienic sealing arrangement is correctly installed before pressurising the system. Observe the specified ambient-temperature limits when operating at elevated medium temperatures. Keep the flush process surface clean during routine operation and maintenance. Use the display or IO-Link interface to verify pressure values and configuration.
