Product Description
The air velocity transmitter is ideal for accurate ventilation control applications. It operates 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 dirty than all other anemometer principles. This
means high reliability and low maintenance costs. CGESAIRVEL is available with current or voltage output, the measuring range and the response time can be selected with jumpers by the user.
Low angular dependence enables easy, cost-effective installation.
