Noise & Vibration Quality Control

Industrial Device Test Solution

The XL2 Analyzer offers an efficient, low-cost solution for industrial quality control. Noise or vibration measurements can be compared against a reference curve with customized tolerance bands. The pass/fail results are provided by the internal tri-color LED or an optional external Stack Light. Integration tools for automation and remote operation are provided.

Pass / Fail Testing

The XL2 Analyzer captures the frequency spectrum of the device under test and supports generation of tolerance bands based on the captured reference data. Measurements can either be displayed as absolute traces or shown relative to previously stored traces. Frequencies with failed results are individually visualized in every frequency band.

In batch production, undesirable vibration in a manufactured product can be detected by means of frequency analysis. The pass/fail test uses the frequency spectrum of a "good" product as a reference and compares it. The XL2 can be integrated into a production line to execute this process. A high-resolution zoom FFT or a CPB spectrum with a resolution of up to 1/12 octave is available for frequency analysis. Trace captures allow simple creation of reference spectra for later comparison.

The pass/fail results are visualized on the display as well as via the Limit LED, and are logged as text files. With the "Remote Measurement" option, measurements can be started via the USB interface and the results retrieved.

Application Example

Integration for (semi-) automated measurements

Stack Light

SPL Stack Light
The XL2 Noise and Vibration Analyzer in combination with this Stack Light provides a turnkey solution for noise level monitoring or pass / fail measurements where a prominent visual indication is required. The Stack Light connects directly to the XL2 Analyzer and shows the actual measurement result with three different colors; green, orange and red.

Digital I/O Adapter PCB

Digital I/O Adapter PCB
For automated operation with external peripheral devices the XL2 Analyzer can be linked into a programmable logic controller. The Digital I/O Adapter is tailored for rail mounting in electric switch boxes.

Product Data
 

Auto-start Function

Measurement starts by automatic level trigger, external foot switch or instrument start button.

Tolerance Management

Tolerance curves can either be imported from txt-files or directly derived from captured measurements. The XL2 calculates tolerance bands based on

  • Single captured results
  • txt-files manually generated on the PC
  • Mean average of multiple captures
  • Min/Max curves of multiple captures

Remote Monitoring

Multiple XL2 Analyzers connect with USB Device Servers to a network for online condition monitoring. Wireless solutions are also supported. An individual Projector PRO Software may be started for each XL2 Analyzer, thus simultaneously displaying all XL2 screens on the PC monitor. Each XL2 Analyzer can be controlled from the host PC.

XL2 Noise Monitoring Network

Individual Solution programmed by Customer

The Remote Measurement Option allows querying of the XL2 measurement data online via the USB interface. Multiple XL2 Analyzers can be implemented into a customer specific solution for quality control. The XL2 acts as a front end device for precise measurements.
