SENSOPHONE S-15P acoustic-emission sensor
The SENSOPHONE S-15P acoustic emission sensor is a mid-frequency, resonance-type, passive vibration detector without built-in preamplifier. It is suitable also for inverse operation with negative voltage impulses. Neodymium magnet is embedded in the base, so it is easy to attach sensor to the ferromagnetic surfaces. The sensor is insulated, so there is no ground loop. The sensing surface is a hard, heat-resistant resin composite.
