High SPL Microphone
up to 170 dBPeak
RG-50HL

The ¼” electret microphone RG-50HL is a free field microphone with integrated electronics designed for the IEPE 4 mA constant current supply at 24 Volt DC.

Microphone sensitivity with 1.0 mV/Pa = up to 170 dB peak.

The membrane is protected against mechanical
damage by a protective grid.

  • IEPE sensor supply => 24 to 30 Volt @ 4 mA
  • Bias: 12.5 Volt
  • 5Hz to 20 kHz
  • up to 170 dB Peak
  • pre-polarized

Application:

  • Airbag Bang
  • Explosion analysis
  • Explosion detection
  • Shooting noise
  • Gunshot sound
  • Engine noise – Aerospace industry

microphone for high sound pressure levels
60 dBA - 186 dB

The 1/4″ microphone set consisting of the MV310 and the microphone capsule MK342 E has a constant pressure curve and is therefore optimized for correct acoustic measurements at interfaces or in acoustic couplers with extreme sound pressure levels.

MK342 E + MV310 set

1/4" IEPE microphone with
constant pressure frequency response

The static air pressure is compensated by means of a capillary to the preamplifier (back-ventilated) or by means of a side capillary (side-ventilated).

The membrane is protected against mechanical
damage by a protective grid.
