DESCRIPTION

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 measuring amplifier with adjustable gain, a USB box 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

Within the context of the experiments in the complete PT 500 series, the following learning can be covered:
- familiarisation with vibration signals
- correct application of FFT analysis
- measurement of rotation speed, vibration displacement, vibration velocity and acceleration
- assessment of the vibration state of a machine
- damage analysis of roller bearings and gears by means of envelope spectra
- detection of cracks in shafts by means of run-up curves and order analysis
- measurement of imbalance vibrations and field balancing of rigid rotors in 1 and 2 planes
