PT 500 - Machinery Diagnostic System

 

The purpose of modern-day machinery diagnosis is to carry out needs-based maintenance or repair and to minimise the repair and other servicing downtimes of a machine. The aim is to detect damage as it occurs.

 
The condition of a machine or of machine components can be accurately diagnosed from the nature and extent of its vibration. Accordingly, vibrations are measured, recorded and evaluated using sensors and recording equipment.

 

Correct interpretation of the measurement signals requires a thorough understanding of the mechanisms at work and a degree of experience.

 

The GUNT PT 500 machinery fault trainer is a modular system which deals with this complex and highly topical issue in technical tuition, developing it through experimentation.

 

A thorough treatment of the subject requires an engineer’s know-how. However, skilled tradesmen and maintenance fitters can use the training system to familiarise themselves with this field of technology at a more practiceoriented level.

 

The PT 500 machinery fault trainer can be used to selectively simulate, measure and evaluate vibration signals generated by typical malfunctions and damage, thus allowing thorough interpretation of the measurement signals to be carried out.

Professional measuring equipment enables the experience gained to be transferred to everyday working practice.

 

Base Unit

 

A range of training exercises relating to machinery diagnosis and monitoring can be carried out using just the PT 500 base unit together with the computerised vibration analyser PT 500.04.

 
As well as the exercises in the measurement of the vibration (amplitude, velocity and acceleration in the time or frequency range), field balancing of rigid rotors and alignment of shafting can also be practised.

 
The base unit includes a vibration-damped workholder plate, a speed-controlled drive motor with a tachometer, a shaft with two mass discs and two bearing units, a coupling and balancing weights.

 
A wide range of accessories enables almost any subject area relating to machinery diagnosis to be covered.
