IFM SI5010 Flow Sensor – SID10ADBFPKG/US-100

The IFM SI5010 thermal flow sensor delivers reliable flow rate monitoring for both liquids and gases in demanding industrial environments. Using a calorimetric measuring principle, the sensor detects flow velocity changes with high repeatability and a configurable PNP switching output. Equipped with IO-Link communication, robust stainless-steel housing, and high pressure resistance up to 300 bar, it is ideal for machine and process monitoring tasks in hydraulics, pneumatics, and cooling circuits.
