The IFM PI2799 is a flush pressure sensor with display designed for hygienic pressure monitoring in food and beverage applications. It measures relative pressure and vacuum from -1 to 1 bar. Two digital outputs, one scalable analogue output, and IO-Link provide flexible process integration. Its flush, no-dead-space construction is designed for hygienic installations involving liquids, gases, viscous media, and suspended particles. The sensor supports medium temperatures up to 125 °C and short-time exposure to 145 °C.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The PI2799 provides a low-pressure range of -1…1 bar. It can monitor both vacuum and positive pressure conditions. The flush construction minimises dead space around the pressure measuring point. This is particularly useful for hygienic process equipment where cleanability is important. The sensor can handle liquids, gases, viscous media, and liquids containing suspended particles.
The sensor uses a G1 Aseptoflex Vario connection for hygienic process installation. Its wetted materials include stainless steel, ceramic, PTFE, and compatible sealing materials. The flush design supports applications in which product residue and dead spaces must be minimised. Medium temperatures can reach 125 °C, with short-time operation up to 145 °C for one hour. IP67/IP68/IP69K protection supports demanding washdown environments.
The PI2799 provides two configurable digital outputs and one scalable 4…20 mA analogue output. IO-Link communication enables digital parameterisation and process-data access. The sensor supports both 2-wire and 3-wire operating configurations. The 4-digit display provides direct local pressure information. These features make the PI2799 suitable for advanced hygienic process automation.

The PI2799 combines pressure measurement, local display, switching, and digital communication. Its low-pressure range makes it suitable for applications where small pressure changes need to be monitored. IO-Link provides access to pressure values and configuration parameters. The analogue output can be scaled to match the required process range. This provides flexible integration into hygienic process-control systems.
Install the sensor using a compatible G1 Aseptoflex Vario process adapter. Ensure that the flush sealing area is clean and correctly seated. The sensor should remain within its specified pressure and temperature limits. Follow the process equipment's cleaning and sterilisation procedures. Inspect the process connection and electrical connector during routine maintenance.
