The sensor housing contains an analog section, a digital signal processing unit and a web server. The analogue part ANALOG amplifies the sensor signal and forms the logarithmic envelop for data reduction. AE parameters such as arrival time, rise time, duration, peak amplitude and energy are extracted from the envelope by the digital signal processing unit PARAM. In parallel to the parameter extraction, the waveform of the envelope can be recorded. The web server generates dynamic web pages to control the sensor and to display the measurement results. Unit RX/TX establishes the connection to the network.

The sensors are available with different Ethernet connectors. IX Industrial® is a miniaturized alternative to the well-known RJ45 connector. For particularly high mechanical requirements, the larger 8 + 2 Pol XLR plug from mobile stage technology is used. The L types have two of these connectors to forming sensor chains for locating.
