Calibrated Measurement Microphones

Acoustic Resonance Analysis
Vibroacoustic Resonance Testing

The IEPE microphones MI15, MI17, MI19, RG-50, and MI21 are types of free-field microphones with integrated electronics that are commonly used in scientific research.

To ensure accuracy, these microphones can be supplied with close tolerances of ±0.5dB and have transfer factors ranging from 10 mV/Pa to 100 mV/Pa.

Constant current power IEPE is the standard power source, usually set at 4mA.

Coaxial cables are used as feed lines, and the standard microphone configuration includes BNC connectors that have optional TNC variations available.

It is important to note that these microphones should not be exposed to harsh environmental conditions due to their sensitive design.
