Accurate condition monitoring in harsh environments
February 2013Maintenance, Test & Measurement, Calibration
BMG has launched a new portable condition monitoring device from SPM Instrument which has been designed for accurate analysis as well as diagnostic and troubleshooting capabilities in harsh environments. The robust handheld Leonova Diamond instrument provides a powerful combination of well-proven measuring techniques and supporting diagnostics for every situation.
“The Leonova Diamond incorporates the latest digital technology and offers advanced slow speed capabilities in a single, portable instrument. This device is not just a predictive maintenance tool – it can also be expanded to perform corrective maintenance such as fast and easy machine alignment and balancing,” says Pieter van Zyl, condition monitoring manager, BMG. “This durable instrument, the newest in the SPM range of condition monitoring products, has been designed for reliable and cost efficient maintenance, as well as extended service life in the most demanding circumstances.”
Core to effective pro-maintenance is up to date information on a machine’s status. Shock pulse monitoring with the SPM HD method gives early warning of bearing deterioration, the most common cause of machine failure. The Leonova Diamond measures vibration velocity, acceleration and displacement according to the latest ISO 10816 standards.
The Leonova Diamond has an excellent signal-to-noise ratio and provides sharp signals, even in areas where signals are normally weak. With advanced tracking functionality, the device measures a machine’s condition in the 1–20 000 rpm range. The wide frequency range between 0 and 40 kHz enables reliable measurement, where absolute position is critical.
This device is also used in machines with journal bearings to measure dynamic and centreline movement of the shaft. Multi-channel measurement enables the use of triaxial transducers and multi-axis vibration monitoring. Previous lengthy measuring routines are now quickly and efficiently conducted.
In machinery operating under variable speed, vibration analysis with HD order tracking provides reliable data and accurate measuring results, even under large rpm variations. The sampling rate is automatically and continuously adjusted to the current speed, enabling more precise measurements and more detailed spectrums than could be obtained previously.
Corrective maintenance techniques, including shaft alignment and dynamic balancing, can be added to this instrument as optional modules. Specially designed modular software supports the Leonova Diamond, providing easy set-up of personalised default settings for exact user requirements. An intrinsically safe version of the Leonova Diamond instrument will be launched locally in the first half of 2013.
BMG’s portfolio of SPM condition monitoring equipment extends from basic hand-held instruments to high level online systems. These products are designed for users at every level – new operators, as well as advanced vibration analysts.
