IEPE Interface - IEPE Sensor DAQ - IEPE USB ADC

Sound and Vibration Analyzer - USB IEPE Sensor Data Acquisition

The IEPE interface Plug.n.DAQ Lite provides a compact 2-channel IEPE sensor data acquisition device for recording and analysis.

The IEPE interface DAQ is equipped with a widely used USB interface so that no additional driver installation is required.

Furthermore, the device is able to directly support IEPE sensors, such as microphones and accelerometers, in addition to AC inputs.

Three fixed input ranges of 1 volt, 5 volt or 10 volt allow optimum adjustment of the sensor signal-to-noise ratio.

The use of filters on the input and instrumentation quality amplifiers ensures the reliability of the data.

The bandwidth of up to 24 kHz per channel and simultaneous sampling make the Plug.n.DAQ Lite extremely flexible and allows it to be used with all software packages that support USB audio devices.

Supported operating systems: Android – Linux – Windows – macOS

FFT Analyzer – Microphone Software Freeware

I would like to take this opportunity to provide a brief introduction to the ARTA software, which includes Plug.n.DAQ Lite MMS 214 Low Noise Microphone and Microphone Calibrator. 

In this demonstration, I will be showing the calibration of the measurement chain.

Gun Test MIL STD 1474D

We would like to propose a method for measuring the noise level of a gun and the vibration at the gun at the same time.

 

To achieve this, we suggest using measuring microphones and accelerometers with a low sensitivity to measure the high sound pressure levels and the high mechanical shock.

 

We are pleased to offer a measurement data acquisition system with an acceleration sensor, measurement microphone and software that is suitable for measuring in accordance with the MIL-STD-1474D standard.

Plug.n.DAQ Lite settings with NVH-FFT

Today we will show you how to set up the Plug.n.DAQ Lite USB IEPE Sensor Interface in conjunction with the NVH Analyzer software.

For a correct display of the sensor amplitudes, the input measuring range of the USB measurement module and the sensitivity of the sensor must be known.

The sensitivity of the sensor can be taken from the calibration certificate of the sensor or it can be determined directly with a vibration calibrator.
