The quality of indoor air is currently becoming increasingly important. Filters are used to monitor the condition of the air in rooms. Our differential pressure transmitters are installed in air conveying systems such as ventilation systems or components of plant engineering and mechanical engineering. In air conveying systems, the conveyed air is to be cleaned from certain substances and particles by using filters. Over time, the filters become increasingly dirty. In order to continue to ensure constant air delivery, the filter contamination must be reduced. Therefore, the capacity of the plant is usually increased. This in turn is associated with a high energy consumption of the plant and losses of the filter. By using our differential pressure transmitters, continuous monitoring of the degree of filter fouling is achieved. Early failure detection also minimizes energy consumption and ensures consistently high air quality.

In modern building technology, the requirements regarding the energy efficiency of ventilation systems are constantly increasing. At the same time, the volume flow in the duct must be kept above a hygienically necessary limit value. By using high-precision differential pressure transmitters, the balancing act between maintaining minimum volume flows and simultaneously energy-efficient operation can be realized. The cross-sectional area of the duct and the k-factor of the differential pressure transducer can be parameterized via software for precise determination of the volume flow by means of differential pressure transducers.

Awareness of the importance of high air quality has increased enormously in recent years. An air quality indicator cannot be defined uniformly, but depends on the requirements of specific applications and thus on various influencing variables. The most common measured variables for determining air quality are temperature, humidity, CO2 and VOC levels, as well as particulate matter. For the demand-oriented control of ventilation systems and the compliance with limit values, transmitters are used that precisely determine and display the parameters and communicate them to the building management system. High-quality measurement systems in building automation thus ensure high air quality with maximum energy efficiency.
