AE PoE Sensors with integrated Acoustic Emission System
Types with data transfer and power supply via Ethernet cable
Main advantages of the PoE types over the WiFi types:
The hit rate over all sensors is greater at 300kHits/s.
Very stable, low-interference network connection with high data rates.
More possibilities for a self-sufficient power supply with solar modules and lithium-ion batteries.
Due to the decentralized signal processing and the network topology used, the cable lengths are reduced to 10%.

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.
