ATEX Flow Switch

Thermal Flow Switch ATEX Rated

ATEX Flow Switch models STS-ST-STEX-LNZ 450 EX22. The function of the flow controller is based on the thermodynamic principle. The sensor is heated internally a few degrees °C compared to the medium into which it projects. When the medium flows, the heat generated in the sensor is conducted away by the medium, i. e. the sensor cools down. The temperature within the sensor is measured and compared to the temperature of the medium. The state of flow can be derived for each medium by the temperature difference attained.
