ICP Microphone – IEPE Microphone
1/4″ Measurement Microphone for multi-channel applications
ICP – IEPE microphones including factory calibration certificate and 24 months warranty.
M380
- Free field
- 20 Hz to 20 kHz
- 21 dB(A) to 135 dB
- IEPE (Microdot)
- Supply: IEPE
- TEDS according to IEEE 1451
- Omnidirectional
The M 380 has a very low series tolerance of sensitivity and frequency response due to its MEMS capsule technology.
It is designed for acoustic measurements where multi-channel microphone arrangements are used, or easy interchangeability of microphones is an advantage.
The small, inseparable microphone capsule and preamp combination can be connected to IEPE-powered measurement channels and calibrated with standard 1/4″ sound calibrators.
The measurement microphone has a Class 1 frequency response according to IEC 61672.

MI19 Identify Defects During Welding
Sonibel Instruments Explanatory Demo with CPO
Sonibel catches weld defects during welding, giving welders the option to rework them on the spot and minimize repair costs.
- Fewer Inspection Bottlenecks Pass inspections the first time and keep projects moving forward.
- Reduced Rework Time Address defects immediately rather than waiting for NDT.
- Less Downstream Delays Minimize the cascading effects of failed inspections on your project timeline.
1/4″ measurement microphones with a pre-polarized capsule deliver a voltage of 3 to 5 mV/Pa and have a self-noise of around 35 dB(A).
With a sensitivity of 100 mV/Pa, the MI19-HS has a twenty times higher output voltage at 24 dB(A) self-noise.
The high signal-to-noise ratio and the high sensor sensitivity have an optimum effect on the resolution of the measurement data acquisition, which leads to better measurement results.
