PI pressure sensor for hygienic applications
Tried and tested product improved: PI pressure sensor now with optimized resolution
For years the ifm pressure sensors of the PI series have proven their worth in the food and beverage industry. But even what is successful can be improved. Pressure changes can now be visualised via IO-Link in high resolution with approximately 20,000 steps. This is an enormous benefit, especially for hydrostatic level measurement with head pressure: In such applications, the sensor must be designed for a larger measuring range in order to withstand the additional head pressure. With conventional sensors, a larger measuring range reduces the resolution of the pressure detection – this problem no longer exists with the PI.
Another advantage: The sensor also detects the medium temperature and transmits it via IO-Link. This means that it is no longer necessary to set up an additional temperature measuring point.
What are the advantages of the new PI pressure sensor?
The sensor has a high-purity ceramic measuring cell. This offers high resistance and long-term stability, even with frequent pressure peaks or overload. In addition, the ceramic is resistant to abrasive media.
The pressure sensors of the new PI1xxx series are ideally suited for pressure measurement in tanks and pipes in food production – for example in dairies, breweries and many other applications where liquids are used.

Harsh environments: spray ball cleaning
Added value thanks to IO-Link
The new PI with 32-bit resolution and approx. 20,000 steps offers a detailed display even across wide measuring ranges.
IO-Link enables loss-free data transmission, as conversion losses are excluded via digital communication and external influences, such as magnetic fields, have no effect on data transmission. Diagnostic data is also provided via IO-Link.
The current pressure is output precisely with the highest possible resolution via IO-Link. This makes it easy to keep an eye on your process at all times. In addition, the medium temperature is output cyclically via IO-Link.
The pressure sensor can be configured quickly and easily via IO-Link.
This is supported by a simulation function, among other things.
Higher resolution, revised design
The new pressure sensors, which are available with different measuring ranges from vacuum to 100 bar, communicate via IO-Link 1.1 and offer a resolution of about 20,000 steps. This is especially important for applications where differential pressures are measured and thus only a small part of the measuring range can be used. Temperature compensation has also been improved in the new series.
