Autonomous wireless sensor

With the Wilsen.sonic.level, Pepperl+Fuchs presents an ultrasonic level sensor that can be used to determine filling heights and filling and level levels.

The measured values are recorded at regular intervals and transmitted to the Internet. The autonomously operating wireless sensor is battery-operated and can therefore also be used away from any power supply infrastructure. The sensor from Pepperl+Fuchs detects the fill or level using ultrasonic distance measurement; it does not matter whether the medium to be detected is a liquid or a fine or coarse granular bulk material. Thanks to its adjustable sonic beam width via mobile app and various evaluation and filter methods, the sensor enables reliable measurement even in dusty and dirty environments as well as in narrow shafts and, for example, containers with struts or other installations.

In addition to the fill level information, further data such as the temperature at the installation site, the battery status and optionally the geoposition are recorded cyclically at the set interval. All data is then transmitted wirelessly from the sensor to the Internet using the globally standardized LoRaWAN technology. Both public and privately operated LoRaWAN networks can be used for this.
