Machine monitoring acoustic sensor M 380

for process monitoringmonitoringmeasurement

The 1/4" M 380 electret measuring microphone has a free-field equalized frequency response of the transmission ratio as well as optimized noise characteristics and is designed in particular for acoustic measurements in the free sound field with a 0 degree angle of incidence. The electrical connection is made via Microdot or BNC cable to measurement channels with IEPE supply. The frequency response of the measuring microphone corresponds to class 1 according to IEC 61672. Thanks to its MEMS capsule technology, the M 380 has a very low serial tolerance of sensitivity and frequency response. It is designed for acoustic measurements where multi-channel microphone arrangements are used or where easy interchangeability of microphones is an advantage. The miniaturized, inseparable combination of microphone capsule and preamplifier can be connected to measurement channels with IEPE supply and calibrated with standard 1/4" sound calibrators. The M 380 opens up a wide range of customized, cost-effective applications. This ranges from the use of a number of microphones in acoustic microphone arrays for enveloping
