AE sensors with preamplifier
AE sensors: For all AE channels. Piezoelectric detectors with or without built-in preamplifier and/or fixing magnet. Used with appropriate contact material/glue and fixing method when putting on the surface of the object to be inspected. Connected to the SENSOPHONE AED4xx or EMA-4 family devices via coaxial cables.
The preamplifiers are powered via the same coaxial cables and can be built-in to the sensor or to the sensor cable itself. The sensor-preamplifier pairs have sensor-test possibility.
