Reliable pressure monitoring with ifm’s PI series sensors
What makes ifm’s PI series sensors the perfect fit for hygienic applications
- Ceramic measuring cell and continuous diagnostics
- Flush, hygienic design for easy cleaning
- Digital precision with IO-Link connectivity
In many industries - especially food & beverage, pharmaceuticals, and hygienic processes - maintaining accurate and safe pressure readings is critical. ifm’s PI pressure sensors are engineered to meet those demands. Their design emphasizes reliability, precision, and safety, making them ideally suited for environments where reliability and performance both matter.
What Makes the PI Series Special
- Ceramic Measuring Cell & Diagnostics
The PI sensors use a ceramic capacitive measuring cell that resists overloads, abrasive media, and frequent pressure peaks. It also performs continuous diagnostics of the measuring cell status, which increases reliability and confidence in the system. - Flush Process Connection & Hygienic Design
The measuring cell is flush with the process media, reducing risk of deposits and making it easier to clean. The housing is fully welded stainless steel and rated to IP69K, ideal for sanitary applications where washdowns, CIP (Clean-in-Place), and aggressive cleaning agents are involved. - High Temperature Handling & Temperature Compensation
These sensors can handle media temperatures up to 150 °C over longer periods and include fast-reacting temperature compensation, so pressure readings stay accurate even with temperature fluctuations. - Digital Resolution & IO-Link Connectivity
With around 20,000 steps of resolution via IO-Link, PI sensors deliver very fine-grained measurement output, which also enables access to process values and diagnostics such as temperature and pressure over the same interface.
Typical Applications
- Tank and Pipe Pressure Monitoring
PI sensors are often used in tanks and piping in food production, where accurate pressure tracking helps maintain safety and quality. - Hydrostatic Level Measurement
Because PI sensors support flush connection and high resolution, they work well for measuring liquid levels via hydrostatic pressure - even in cases with foam or turbulence on the surface. - Pressure Control in Cleaning Cycles
Spray ball cleaning and CIP systems require sensors that can withstand rapid pressure spikes, high temperatures, and chemical exposure. PI sensors operate reliably in these conditions.
Advantages for Users
- Increased uptime due to durable sensors and fewer failures
- Better data quality for process control, especially under difficult conditions
- Reduced risk of contamination thanks to hygienic design and flush connections
- Easier system integration and parameterization via IO-Link
Conclusion
ifm’s PI sensors deliver precise and hygienic pressure monitoring, especially in environments with demanding cleaning regimens, temperature changes, and strict safety requirements. For operations that depend on reliable pressure data to maintain safety and product quality, the PI series is a strong choice.
