Kobold, represented locally by Instrotech, has the compact KAH Series airflow velocity transmitters, ideal for accurate ventilation control in Building Automation Systems (BAS) and heating, ventilation and air-conditioning (HVAC) applications.
They incorporate innovative hot film anemometer technology which guarantees good accuracy at low airflow velocity and makes the sensor highly reliable and heat resistant against dust and dirt. This technology is superior to conventional anemometers with hot wire sensors or NTC bead thermistors. The sensor is much more insensitive to dust and dirt than all other anemometer principles which translates to high reliability and low maintenance costs. The configuration equipment allows air velocity adjustment of the sensor.
Apart from measuring air flow velocity, the KAH air flow transducer transmits a normalized signal of 4-20 mA or 0-10 V. The measuring range and the response time can easily be selected with jumpers as per requirement.
- Selectable working range: 0 … 10/15 /20 m/s
- Output signal: 0 …10VDC or 4 …20mA
- Supply voltage 24VAC/DC
- Low angular dependence
