Operating on a unique hot-film anemometer principle, the KAH air velocity sensors target applications requiring accurate ventilation control. The thin film sensors guarantee accuracy at low air velocity, which allegedly is not possible for conventional anemometers with commercial temperature sensors or NTC bead thermistors. As per the company, the sensor is also much more insensitive to dust and dirt than all other anemometer principles. The configuration equipment allows air velocity adjustment of the sensor. The measuring range and the response time can be selected via jumpers by the user. This facilitates easy adjustment to the correct working range upon startup. By use of the supplied mounting bracket, the insertion depth is infinitely adjustable.
