Product Overview: ifm electronic PI2798
The ifm electronic PI2798 is a high-precision electronic pressure sensor designed for versatile industrial applications. Part of the PI series, this sensor is engineered to provide reliable monitoring of system pressure in liquid and gaseous media. Featuring a high-visibility, rotatable 4-digit alphanumeric display and IO-Link communication, the PI2798 is a core component for modern automation environments where real-time data and remote diagnostics are essential.
Technical Specifications and Digital Integration
The PI2798 offers a measurement range from -1 to 25 bar (-14.5 to 362.5 psi). It is equipped with a ceramic-capacitive measuring cell that is exceptionally resistant to overpressure and mechanical wear. The integrated IO-Link interface allows for digital transmission of pressure values and device parameters, facilitating «Plug and Play» sensor replacement and advanced predictive maintenance. It provides two switching outputs or one switching and one analog output (4-20 mA / 0-10 V).
