MI19
Calibrated microphone MI19 is suitable for all measurements in technical acoustics such as machine noise, sound measurement on test benches, use in impedance tubes, sound testing and acoustic cameras.
IEPE microphones MI15, MI17, MI19, RG-50 and MI21 are types of free-field microphones with integrated electronics that are often used in scientific research.
To ensure accuracy, these microphones can be supplied with tight tolerances of ±0.5 dB and have transmission factors from 10 mV/Pa to 100 mV/Pa.
A constant current source IEPE is used as standard, which is usually set to 4 mA.
Coaxial cables are used as feed lines and the standard microphone configuration includes BNC connectors, which are also optionally available as TNC variants.
It can be used in combination with any device that has an IEPE supply.
