Wireless differential pressure sensors are used to measure pressure difference between two rooms. These senssors are used in clean rooms and in every room that are connected with an airlocks. Sensors work with Android applications (Efento Inspector, Efento Logger) and Efento Cloud platform. The battery ensures maintenance-free operation for at least two years. The sensors communicate wirelessly with smartphones or Efento Gateway in Bluetooth Low Energy technology.The maximum range is approx. 100 m in line of sight. Temperature sensors have built-in memory which stores 60 000 measurements.
On request, each of the Efento sensors can be supplied with a calibration certificate in accordance with ISO/IEC 17025. The procedure is carried out in an external test laboratory, using laboratory equipment calibrated with reference to international standards.
The sensors are compliant with European directives and standards and CE marked.
