PC measurement technology - USB data acquisition - NVH analysis

NVH measurement for education, industry, research and development

ROGA Instruments offers systems for data acquisition and analysis.
 
We develop hardware and software for demanding measurement, monitoring and analysis tasks for science, research and development as well as for industrial purposes – all from a single source.
 
ROGA-Instruments produces IEPE measurement microphones and digital IEPE USB sensor conditioners.
 
Here you will find system solutions for sound measurement technology and vibration measurement technology, modal analysis, general measurement technology and special applications, sound analysis, vibration analysis, long-term and high-speed measurement data acquisition, secure measurement data storage, real-time analysis, vibration monitoring, control applications and regulation applications as well as machine control.

Vibration measurement for the early detection of approaching objects at long distances.

This presentation demonstrates the early detection of approaching trains from a distance of 2 km.

The system combines a highly sensitive IEPE accelerometer with very low inherent noise, a USB measurement card with an optimal measurement range and low inherent noise, and vibration monitoring software.

USB Measurement Card With and Without Anti-Aliasing Filter

This presentation explains the difference between measurement cards with and without anti-aliasing filters.
 
In this example, a 30 kHz signal is input.
 
The USB measurement card without an anti-aliasing filter incorrectly measures a 14 kHz signal at full energy.
 
Data acquisition without an anti-aliasing filter is unsuitable for dynamic sensor signals and leads to measurement errors.

High Sound Pressure Level Measurement

High SPL measurement microphone system according to MIL-STD-1474E.

This presentation illustrates a high-level microphone measurement using the LTTsmart NVH SET at a sampling rate of 1 MHz with 24-bit ADC resolution.

It includes the necessary anti-aliasing filters and IEPE sensor power supply.

Infrasound - Structure-borne sound measurement

In this presentation, I will demonstrate how infrasound and low-frequency building vibrations can be measured using a seismic accelerometer.

The measured structure-borne sound source, with a frequency of 80 Hz * 60 seconds, with 4800 rpm, is a NAS fan located in the corner of a building.
