The XL2 with Spectral Limits Option offers an efficient, low-cost solution for industrial quality control. 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.
FFT Analysis
Compares the high-resolution acoustic pattern of any device against a pre-defined reference sample with a pass/fail analysis in linear X-scaling. The detailed frequency analysis allows identifying problematic frequeny bands to reduce the noise generated by the device.
1/12 Octave Analysis
Passed/Failed measurements with selectable 1/1, 1/3, 1/6 or 1/12 octave band resolution in logarithmic X-scaling.
Pass/Fail Measurements
The XL2 Analyzer captures the frequency spectrum of reference speakers/microphones 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.
Auto-start Function
Measurement starts by automatic level trigger, external foot switch or instrument start button.
Stack Light
Provides visual pass/fail indication.
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
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.
Remote Monitoring
Multiple XL2 Analyzers connect with USB Device Servers to a network for online noise monitoring. Wireless solutions are also supported. An individual Projector 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.
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 noise monitoring solution. The XL2 acts as a front end device for sound level measurements.
