The FS Series, based on the principle of the hot-film anemometer, is suitable for a wide range of different applications, with the tried and tested thin-film technology guaranteeing ultimate reproducibility and long service life.

Essentially, the FS5 Sensors consist of a heater and a temperature sensor. The heater is heated up when voltage is applied. A flow causes it to cool down, and the drop in the heater's resistance is measured. The configuration of the heater and of the temperature sensor in the FS5 is such that a measuring range of up to 100m/s in gases (PDF 75,0 kB) and a measuring range of up to 10m/s in liquids (PDF 79,0 kB) can be covered. The low mass of the sensor results in rapid response times and short temperature ramp-up tmes. The temperature range in use reaches from -30°C to +150°C. The element is available with a plastic holding fixture, allowing the sensor to be installed easily in customer-specific enclosures.

The FS2 (PDF 81,0 kB) Sensor has been designed for exact measurements of minute flow speeds and is therefore the ideal solution for laminar flow monitoring and other applications in ventilation engineering. The special arrangement of the four thin-film sensors also allows the detection of the flow direction and of the reference temperature in a small and compact design. Again, the temperature range goes from -30°C to +150°C. The electrical connection is open to customer-specified design. If required, the sensors can also be supplied with matching ZIF plug-type connectors.

The special membrane technology of the microflowSens™ (PDF 74,0 kB) sensors boasts an extremely rapid response time in the single digit micro second range. This makes the microflowSens™ technology the optimum solution for applications in medical and ventilation engineering. The measuring range goes as high as 1m/s, with the temperature range in use between -30°C and +150°C. Directional detection and the measurement of the reference temperature round off the outstanding technical options with an excellent price-performance ratio.
