Our RG-50 IEPE microphone is an excellent choice for technicians and engineers in various fields, including acoustics, automotive testing, aerospace, and more. It is designed with a low noise floor, making it perfect for capturing frequencies from infrasound to ultrasound. 

With a high sensitivity of 50 mV/Pa, this microphone captures even the slightest sound accurately.

Our RG-50 IEPE microphone has been a trusted choice for researchers and developers worldwide for over 20 years. Its compact size and rugged design make it ideal for use in a wide range of applications. Whether you are conducting environmental noise analysis or investigating mechanical and structural vibrations, the RG-50 IEPE microphone will provide you with the reliable and accurate data you need.

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.
