IFM PI2889 Flush Pressure Sensor with Display

Product overview

The ifm PI2889 (PI-,10BREA01-MFRKG/US/ /P) is a flush pressure sensor with display for liquids and gases, including viscous media and liquids with suspended particles. It measures relative pressure over -0.005…0.1 bar (-5…100 mbar), with a pressure rating of 4000 mbar and a minimum burst pressure of 30000 mbar. The process connection is a G 1 external thread with 27 mm sealing cone, the wetted parts are ceramics (99.9 % Al2O3), stainless steel (1.4435 / 316L) and PTFE, and the permitted medium temperature is -25…125 °C. It provides 2 switching outputs (PNP/NPN), 1 analog output (4…20 mA) and IO-Link, runs on 20…32 V DC and connects through an M12 connector (A-coded, 4 gold-plated contacts). ifm specifies characteristic deviation < ± 0.5 % of span and repeatability < ± 0.1 % of span. The sensor is rated IP67, IP68 and IP69K for -25…80 °C ambient. ifm notes that it must only be installed in a process connection for a G1 sealing cone, and only with adapters that have a metal end stop.
