ROTEC MEASUREMENT TECHNOLOGY

From measurement to report

Select analyses in the time or spectral domain, using time-based or angle-based variables.

Measurements & online graphics

Setting and performing measurements of speed, analogue, CANbus, temperature and strain gauge channels

Online graphics for visualisation during the measurement, including time curves, spectrum, single order, sum value and difference channel calculation

Limit value monitoring and alarm output of the trigger card can be configured

Evaluation

Comprehensive analyses in both the time and spectral ranges

The common time base of all channels enables reliable multi-channel evaluation of speed channels and the reference of analogue measured variables to a speed channel

Analysis of torsional angle and gearbox transmission error

Visualisation & Report

Use of the modular system with predefined graphic modules

Waterfall, contour and Campbell representation, 3D representation with lines, meshes and colour levels

Interactive graphics (zoom, rotate, measuring pointer, sectional diagrams)

Placeholders & processes

Placeholders, sequences and the remote control function allow measurements and analyses to be automated and integrated into a testing machine

Typical applications in the end-of-line inspection of gearboxes and gear pairs
