Air velocity sensors which are specially optimised for application for clean rooms and air conditioning.
The “hot film pressure gauge principle” is applied as a measuring method which enables very high measuring accuracy from 0.15 m/s.
The sensors are available for measuring ranges from 0 – 1 m/s to 0 – 20 m/s and output 0 – 10 V or 4 – 20 mA proportionally over their measuring range.
The design of the measuring head enables a direction-independent measurement over a wide range. The air velocity sensors are therefore easy to mount. A mounting flange is included in delivery which allow a continuous installation depth, for example into a duct.
The sensors have a connection housing which contains the evaluation electronics. The output signal, the measuring range and the response time can be selected by jumpers. Optionally the connection housing is mounted firmly on the sensor element or connected permanently by a 2 m long connecting cable.
