Vibration monitor for rotating machines

The Monitran condition monitoring system monitors and logs vibration in rotating machines. The device can measure as many as 32 channels. Parameters that can be measured include velocity and envelope g, as well as temperature. Known as the MTN5032, the microcontroller-based system has an easy-to-navigate 18,5 cm colour touch screen which enables users to set alarm […]

Causes and control of electrical machine vibration

  This article examines the causes of electrical machine vibration, the effects of vibration, and means taken to mitigate vibration. All rotating machines, no matter how well designed and manufactured, exhibit vibration of some form when operating. Excessive vibration can cause damage to the machine or reduce its lifetime, as well as damage to other […]

Measuring the transverse sensitivity of vibration transducers

  The National Metrology Institute of South Africa (NMISA) has implemented a system to measure the transverse sensitivity of vibration transducers. As a mechanical device, the principle sensing axis of an accelerometer is not 100% perpendicular to the mounting axis. This gives rise to the effect that the accelerometer will produce an electrical output even […]
