The KAH air velocity sensor is designed to assist in precise ventilation control. They operate on the innovative principle of a thermal film anemometer. This thin-film sensor guarantees accuracy even at low wind speeds. This is not possible with conventional anemometers with commercial temperature sensors or NTC bead thermistors. In contrast to any other anemometer principle, the sensor is also insensitive to dust and dirt. Plastic KAH offers high reliability and low maintenance costs. The configured electronic meter allows the air velocity of the sensor to be adjusted. The user can select the measurement range and response time through the jumper. This feature ensures that adjustments can be made easily to get the correct working range when commissioning. The insertion depth can be adjusted via the included mounting bracket.
