Robust high-resolution pressure sensor

A successful product improved even further

The ifm pressure sensors of the PI series have proven their worth in the food and beverage industry for many years. The key to success lies in the extremely robust ceramic measuring cell, which can easily withstand even extreme pressure peaks and overloads. Ceramic is also resistant to abrasive media.
Unlike conventional sensors with a metallic diaphragm, no oil is required as a pressure transfer medium. This eliminates the risk of medium contamination when the sensor is damaged. As a result, the ceramic measuring cell offers maximum safety, especially in applications in the food and beverage industry. A new feature is an advanced diagnostic function that continuously monitors the status of the measuring cell. It provides maximum confidence in the measurement while also meeting the documentation requirements of critical processes.

Sophisticated compensation for temperature changes

With pressure sensors, highly dynamic temperature fluctuations often lead to a scenario where the measured values only slowly approximate the actual pressure value. The new dynamic temperature compensation on the PI balances these effects in tanks and pipes by using an intelligent algorithm, making the measurement signal even more reliable.

IO-Link

IO-Link enables not only the loss-free digital transmission of measured values, but also the sensor configuration and provision of diagnostic data, e.g. excess temperature or measuring cell monitoring. Alternatively, the sensor can also be configured on site using the conventional method with three operating keys and a setting menu.

High resolution

The resolution of the IO-Link signal has been increased to 20,000 steps, especially for hydrostatic measurement in tanks.
