AE SPE Sensors with integrated Acoustic Emission System

Types with data transfer and power supply via Single Pair Ethernet cable


Main advantages of SPE sensors:


G4-SPE-Sensor, Höhe 43 mm

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

The maximum power consumption is 105 mW. If the threshold is not exceeded, only 55 mW are consumed. Self-sufficient power supplies are described in Service ⁂ Overview. Products ⁂ Mid Device gives an example of reducing cable lengths.
