KAH Air Velocity Sensor
Brand: KOBOLD Instruments, IncThe KOBOLD KAH air velocity transmitters are ideal for accurate ventilation control applications. They are operating on an innovative hot film anemometer principle.
The thin film sensor guarantees very good accuracy at low air velocity, which is not possible for conventional anemometers with commercial temperature sensors or NTC bead thermistors.
Moreover, the sensor is much more insensitive to dust and dirt than all other anemometer principles. This means high reliability and low maintenance costs. The configuration equipment allows air velocity adjustment of the sensor.
