IP55 splash water resistant
The 19SW microphone has been designed to be IP55 splash water resistant.
The microphone is therefore suitable for use in measurement campaigns in wet and damp weather conditions.
An IP55 water-repellent seal on the membrane at the sound inlet prevents potential damage to the electret capsule caused by water.
The IEPE microphone is suitable for use in standard industrial environments and for all noise measurements with a sound pressure level of up to 130 dB.
Calibration is possible with a commercially available microphone calibrator and a 1/2″ to 1/4″ adapter.
The MI19 microphones are equipped with a BNC socket so that standard BNC cables can be used.
A TNC plug version is also available on request.
The MI21 microphone is designed to be splash-proof so that it can be used for measurement campaigns in wet or damp weather. A water-repellent seal on the membrane at the sound inlet prevents the electret capsule from being damaged by water.
The IEPE microphones with splash water protection, including MI17SW and RG-50SW, have proven their worth with brake manufacturers, among others, who mount the measurement microphone in the wheel arch in order to record disruptive brake noises.
IEPE microphone for all applications in standard industrial environments. Suitable for all noise measurements above 26 dB(A) up to 130 dB.
