Már nem gyártott AE készülékek

Already not produced but supported AE equipments

The SENSOPHONE AED40/xx family of acoustic-emission devices was the first production designed and produced by Gereb es Tarsa Company. Devices, with AE channel number from 4 to 32, are built on full featured four-channel AE modules. The housing contains upto eight AE modules, an industrial single board computer, a 16-channel parameter module, and a power supply module. If the application needs more AE measuring channels, two similar devices can be connected to create a multi-channel system upto 64 AE channels. AE sensors, equipped with preamplifiers and sensor cables, are connected to the main devices through the external programmable main amplifiers LLA102 or LLA103.

The SENSOPHONE AED40/xx family of acoustic-emission devices, with some modifications and with different software, was produced under name as EMA-3 system, too.

This family of AE equipment is no longer produced but previously sold equipment is still supported.

Up to year 2003, the SENSOPHONE AED40/xx devices were built into other housing:
