PT 500.04: Computerised Vibration Analyser

Print Ask to this Articlel

Computerised Vibration Analyser

Computerised Vibration Analyser Computerised Vibration Analyser Computerised Vibration Analyser

Product Details

Technical Description 
The computerised vibration analyser was developed specially to support analysis of machinery diagnosis experiments of the PT 500 series. The analyser can also be used in many other vibration experiments (such as TM 150).
The system comprises two acceleration sensors, a measurement amplifier with adjustable gain, a PCI data acquisition card with a high sampling rate, and the analysis software.
The analysis software offers the following features: Two-channel oscilloscope for investigations in the time range; two-channel spectrum analyser for investigations in the frequency range; vibration measuring device; envelope analysis for bump effects and roller bearing damage; travelling filter to record run-up curves; orbit display; and a balancing module for field balancing of rigid rotors in 1 and 2 planes.
The software permits various analytical methods to be applied to a vibration signal and compared in terms of their efficacy. This enables the advantages and disadvantages of the various techniques to be effectively discovered. The balancing process is presented step-by-step.

The software features an intuitive user interface, and is highly user-friendly. An online help function provides guidance on the various functions. Measurement results can be printed out.

Cables, brackets and fixings are supplied.

Learning Objectives / Experiments
