Splash Proof IP55

  • The RG-50SW NVH DAQ measurement microphone is designed with splash water protection so that it can be used for measurement campaigns in wet or humid weather.

  • A water-repellent sealing of the membrane at the sound inlet, prevents the damage of the electret capsule by water.

  • The IEPE microphones with splash water protection, also MI21 and MI17SW, have proven themselves, among others, with brake manufacturers, who mount the measurement microphone in the wheel housing in order to record disturbing brake noises.
