PT 500 Machinery Diagnostic System, Base Unit Show data sheet (pdf file) Print page
Technical Description

  The machinery diagnostic system can be used to simulate certain types of damage and investigate its effects on the vibration spectrum.

  The PT 500 base unit permits vibration measurement exercises (measurement of vibration displacement, velocity and acceleration in the time/frequency range). Field balancing of rigid rotors and alignment of shafts can also be practiced.

  The key components of the base unit are the mechanical elements (clutch, bearing blocks and shaft with rotors), the drive motor with variable speed via frequency converter and tachogenerator, and the control unit with digital displays for power output and speed.

  The motor base plate is mounted on a carriage, enabling the motor to be aligned. The large aluminium base plate with locating slots allows quick, flexible and precise assembly of the system components. A transparent protective cover provides the necessary safety during operation, and enables clear system viewing during experiments.

  All parts are clearly laid out and well protected in a storage box.

  To measure and evaluate all experiments, the computerised vibration analyser PT 500.04 is required. The accessory sets PT 500.10 - PT 500.19 enable repeatable simulation of the different types of damage.

  Use of the trolley PT 500.01 is recommended for flexible deployment of the training system.
