IFM PI2798 Flush Pressure Sensor -12.4-250 mbar IP69K 4-20mA IO-Link

Overview
The IFM PI2798 (PI-,25BREA01-MFRKG/US/ /P) is a high‑precision flush pressure sensor with display, specifically engineered for hygienic applications in the food and beverage industry. Designed with a flush‑mount ceramic measuring cell and a robust stainless steel 316L housing, this sensor delivers reliable relative pressure measurement across liquids, gases, and viscous media – even in environments exposed to aggressive cleaning agents or extreme temperature fluctuations.

The unit serves both as a pressure switch and as a pressure transmitter, featuring two programmable switching outputs (PNP/NPN, NO/NC configurable) and one scalable 4‑20 mA analog output. Integrated IO‑Link V1.1 communication enables remote parameter setting, process data transmission, and diagnostic capabilities, reducing downtime and simplifying maintenance.

With a 4‑digit alphanumeric LED display providing clear visual feedback of current pressure and switching status, the PI2798 offers intuitive local operation via buttons or remote configuration through IO‑Link. Rated IP67, IP68, and IP69K, the sensor withstands high‑pressure washdowns and CIP/SIP cleaning processes, guaranteeing long‑term reliability in hygienic production lines.

Key Features

• Original brand new, within warranty period – Factory‑sealed, genuine IFM component with full manufacturer warranty.

• 100% Satisfaction Guarantee – Risk‑free purchase; if you are not completely satisfied, we will replace or refund.

• Hygienic flush‑mount design – Flush‑mount design with no dead space, featuring a high‑purity ceramic measuring cell (99.9% Al₂O₃) and stainless steel 316L housing. Meets EHEDG certification and FDA material compliance, preventing contamination in sanitary applications.

• Resistant to high‑pressure cleaning with aggressive cleaning agents – Triple‑rated IP67 / IP68 / IP69K protection ensures reliable operation under high‑pressure washdowns and CIP/SIP cleaning cycles, even with aggressive cleaning agents.

• High temperature resistance – Medium temperature range from -25°C to 125°C (up to 145°C for 1 hour), ambient temperature from -25°C to 80°C, suitable for demanding thermal processing environments.

• Programmable analog and switching output – 2 configurable digital outputs (PNP/NPN, normally open / normally closed) and 1 scalable analog output (4‑20 mA, invertible), enabling flexible integration into diverse control systems.

• IO‑Link V1.1 communication – Integrated IO‑Link interface (COM2, 38.4 kBaud) with minimum process cycle time of 2.3 ms enables remote parameter setting, process data readout, and extended diagnostics, reducing downtime and simplifying maintenance.

• High accuracy measurement – Switch point accuracy of ≤ ±0.2% of span, repeatability ≤ ±0.1%, and linearity deviation ≤ ±0.15%, with electronic temperature compensation for consistent performance in both liquid and gas media.

• 4‑digit alphanumeric display with status LEDs – Easy‑to‑read 4‑digit LED display with green unit LEDs and yellow switching status LEDs provides real‑time pressure indication and simplifies commissioning and troubleshooting.

• Aseptoflex Vario G1 process connection – G1 external thread Aseptoflex Vario connection ensures a dead‑space‑free, hygienic installation compatible with industry‑standard sanitary fittings.

• Gold‑plated M12 connector contacts – M12 A‑coded connector with gold‑plated contacts ensures corrosion‑free signal transmission for long‑term reliability in washdown environments.
