Flow sensors - Sensors for air
The function of the flow sensor involves the calorimetric principle. The sensor is heated from the inside by a few degrees Celsius relative to the flow medium into which it protrudes. When the medium flows, the heat generated in the sensor is dissipated by the medium. The temperature within the sensor is measured and compared with the medium temperature, which is also measured. The setting of the temperature within the sensor is determined from the resulting temperature difference. The flow condition for each medium can be determined. The application of these sensors includes monitoring of cooling systems, ventilation systems, and dry-running pumps, as well as detection of the presence of liquid or gas flows.
