Measurement acoustic sensor AM4I

airborne noisehigh-sensitivitywith built-in preamplifier

The AM4I Sensor is a rugged, high sensitivity airborne, AE Transducer with its peak sensitivity at around 40 kHz. The narrow frequency response reduces noise and increases signal to noise ratio. The sensor's enclosed diaphragm design ensures a high sensitivity and protects the sensing element from the environment. The sensor has a 40 dB preamplifier inside its cavity. It can be connected to our standard AE Data Acquisition Systems just like our other AE Sensors, using phantom power (where power supply input and sensor output signal are combined on the co-ax center conductor).
