high-dynamic and
high-precision sensors

eddylab software


Eddylab is a powerful windows software used in conjunction with the TX-Driver. The targeted area of application is the visualisation and documentation of mechanical motion and the on-site linearisation of eddy current sensors.

eddylab as analysis tool

eddylab is made up as an universal analysis tool for the USB based data stream from the TX-Driver. The requirements in signal analysis can be of various nature - therefore eddylab is structured in several modules. The different modules can be used to monitor fast and slow motion. The measured data can be displayed in the time- and in the frequency domain. The underlying sampling rates are 22.5 kSa/s in the two channel version and 38 kSa/s in the single channel version.

The three different eddylab versions and their functionality

eddylab is available in three different versions: Lite, Standard and Reference. The Lite Version – delivered with every eddy current sensor system – offers an Oscilloscope function.
The eddyab standard Version provides further features as FFT analyser, Waterfall and Data logger. The eddylab Reference Version enables the on-site linearisation of eddy current sensors with an active feedback system.
 

 

 

 

 

 


Sampled data is displayed with basic measurements in the style of a classical oscilloscope
