Application

Rotating parts in drives, gears, pumps, fans and many other technical products cause perturbing vibrations. Different rotation speeds cause different vibrations since the measurement objects develop or do not develop resonant behaviour at certain rotation speeds.

These differences become obviously when measuring run-up or coast-down curves. A rotor changes its rotation speed and excites different frequencies of the system.

The InnoAnalyzers Speed measure the vibration level and phase angle at the rotation speed or a multiple and graphically indicate magnitude and phase at the respective rotation speed. This way, for instance resonant rotation speed levels are detected. The evolution of the rotation speed is displayed graphically as well.

For rotation speed detection, VibroMatrix applies a high quality photoelectric reflex switch. By means of background suppression, it only reacts to its reflector. Optionally, an existing rotation speed signal can be fed as pulse/revolution.

Properties

The InnoAnalyzers Speed in Standard and in Pro Version not only master rotation-speed-selective filtering but also band-pass filtering of the vibration signal and and its display as sum parameter above the rotation speed. In addition to vibration acceleration, the Pro version is also able to analyze vibration velocity and vibration displacement.

Two cursors are available for the evaluation. They can be moved freely or positioned precisely by button. Frequency and magnitude values at the cursor position are presented numerically.

The clone function makes it possible to operate several InnoAnalyzers at the same time. For example vibrations can be analyzed at the rotation speed and at a multiple of the rotation speed at the same time.

The export of data into other applications as bitmap/PNG file for documentation or as text for further examination provides additional fields of application.
