The IFM SI5002 is a thermal flow monitor designed for reliable monitoring of liquids and gases in industrial piping systems. It provides adjustable flow detection with a liquid setting range of 3…300 cm/s and a gas setting range of 200…3000 cm/s. The sensor provides two digital switching outputs with configurable NO/NC functions and IO-Link communication. Its stainless-steel construction and high pressure resistance support demanding industrial installations. The SI5002 is suitable for flow monitoring, pump protection, cooling circuits, and process automation.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The SI5002 uses calorimetric flow measurement for dependable detection of moving liquids and gases. Its adjustable switching point allows the sensor to be matched to different flow conditions. The device provides rapid response with a configurable response time of 1…10 seconds. A built-in LED display provides visual indication of operating and switching status. This makes the sensor suitable for continuous machine and process monitoring.
The SI5002 supports IO-Link COM2 communication at 38.4 kBaud. Two digital outputs provide configurable switching signals for automation controllers. The sensor supports parameterisation through pushbuttons as well as digital communication. IO-Link simplifies commissioning, diagnostics, and sensor configuration. This makes the SI5002 suitable for modern PLC-based automation systems.
The sensor uses stainless-steel wetted components and a robust industrial housing. It supports medium temperatures from -25…80 °C and pressure resistance up to 300 bar. Reverse-polarity, short-circuit, and overload protection improve electrical reliability. An M18 × 1.5 internal thread is provided for process installation. The M12 connection supports secure industrial wiring.

The SI5002 provides adjustable flow monitoring for both liquid and gaseous media. Its high sensitivity ranges of 3…100 cm/s for liquids and 200…800 cm/s for gases allow precise switching adjustment. Repeatability for water is specified at 1…5 cm/s under defined conditions. Temperature drift is specified at 0.1 cm/s × 1/K under the stated water test conditions. These characteristics make it suitable for dependable threshold-based flow detection.
Install the SI5002 using the specified M18 × 1.5 process connection and suitable adapter. Position the probe correctly within the flow path according to IFM installation requirements. Avoid excessive contamination around the sensing probe. Verify the switching point after installation and during commissioning. Periodic inspection of the connector, probe, and process connection helps maintain reliable operation.
