The IFM SI5007 is a thermal flow monitor designed for simultaneous flow and temperature monitoring. It detects liquid flow from 3…300 cm/s and gas flow from 200…3000 cm/s. The sensor provides two programmable switching outputs with NO/NC functionality. Temperature monitoring is available from 2…80 °C, providing additional process information. Its stainless-steel construction, 300 bar pressure rating, and IP67 protection make it suitable for demanding industrial installations.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The SI5007 combines flow monitoring with temperature detection in one sensor. This allows users to monitor both flow conditions and thermal conditions within the same installation. The liquid flow setting range is 3…300 cm/s. The gas range extends to 200…3000 cm/s. Temperature switching provides an additional protection and monitoring function.
The unit has two digital outputs that can be configured as normally open or normally closed. Each switching output can handle up to 250 mA. Pushbuttons allow straightforward adjustment of the switching point. Short-circuit and overload protection improve electrical safety. The sensor can therefore be connected directly to industrial control systems.
The SI5007 uses stainless-steel wetted components and a stainless-steel housing. It supports medium temperatures from -25…80 °C and pressure resistance up to 300 bar. The probe length is 45 mm. An M12 connector provides the electrical interface. IP67 protection supports use in demanding industrial environments.

For water under specified conditions, repeatability is 1…5 cm/s. Factory-condition switch-point accuracy is specified at ±2…±10 cm/s. Hysteresis is 2…5 cm/s. The maximum medium temperature gradient is 300 K/min. These characteristics support reliable threshold-based flow monitoring in industrial systems.
Install the probe according to the specified process connection and flow direction requirements. Ensure that the sensing element is correctly positioned within the medium. Avoid excessive deposits around the probe. Configure the flow and temperature switching points during commissioning. Inspect the sensor and M12 connection periodically for mechanical or electrical damage.
