ICP Microphone – IEPE Microphone

ICP – IEPE microphones including factory calibration certificate and 24 months warranty.

Microphone with High Sensitivity 100 mV/Pa
Range 24 dB(A) to 130 dBPeak

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.

High SPL Microphone

MNP47

The MNP47 1/4″ measurement microphone opens the possibility of using a high-quality, pre-polarized ¼” pressure field measurement microphone capsule on measurement systems with IEPE supply.

Typical applications are measurements of high sound pressure levels e.g. in the defense industry or development of rocket engines or noise measurement in high voltage arc experiments.

The measuring microphone is connected to the measuring channels via a fixed SMB connector with SMB cables or usual BNC cables via a SMB-BNC adapter.

Measuring range, sound pressure level and microphone sensitivity.

A typical 1/2″ measurement microphone delivers a voltage of 50 mV at 1 Pascal. 1 Pascal corresponds to a sound pressure level of 94 dB. 94 dB is already very unpleasant for humans and is only tolerated in rare situations.
 
During a normal conversation, the sound pressure level is below 74 dB, i.e., 20 dB lower. 20 dB quieter is a factor of 10 quieter.
 
This means that at 74 dB, the microphone only delivers 5 mV.
 
Assuming that end-of-line testing involves acoustically testing parts in a soundproof test chamber, it can be assumed that the measurement microphone delivers only a few microvolts.

Low Noie IEPE Microphone USB DAQ

The choice of the input measurement range for the measurement data acquisition is therefore crucial. Assuming that the measurement card has a measurement range of 10,000 mV and the measurement microphone is exposed to a sound pressure level of 74 dB, which delivers 5 mV, the 10,000 mV measurement range is significantly too coarse for this application.
 
The difference becomes even more apparent when you consider that verbal interaction is reduced in the office. At a sound pressure level of 54 dB, the voltage detected by the measurement microphone is 0.5 mV.
 
The comparison scenario with a scale with a 10,000 kg measurement range illustrates that weighing a 0.5 kg object is associated with a high degree of inaccuracy.
 
Our solution for this application is the PnDL-100 with an input measurement range of 100 mV, which delivers an acoustic measurement range of 13 to 97 dB(A).
