Measuring Air Flow in 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.

Apart from measuring air flow velocity, the KAH air flow transducer transmits a normalized signal of 4-20 mA or 0-10 V, with the measuring range and the response time selectable in the field as per requirement.

Compact Turbine wheel Flow Meter

Due to their compact design, the sturdy flow meters of the DRS type from KOBOLD Messring GmbH in Hofheim, Germany, can be used even if little space is available. The measurement method, which uses a sapphire-supported turbine wheel and is suitable for liquid media, is extremely low-wear, since the revolutions are sensed in a non-contact manner by magnets from outside. Based on the high repeatability of 0.1% of full-scale, this reliable measuring device with long term stability is highly qualified for batching tasks.

The versatile modular system allows the devices to be designed to fit the particular application. Their ready integration into automation and control systems is made possible by different electronics provided with standard industrial outputs. Variety of available options range from simple sensors with direct Hall sensor output signal to complex devices featuring an anal...

Under high pressure

A large range of options allows individual and exact setting of the differential pressure gauge to match the relevant application and medium. Of course, the gauges can also be designed for process control with switch contacts. In addition, designs with suitable damping fluids allow its use in the case of strong pressure surges and vibrations. When connected to suitable p...
