Multiple measuring assignments can be carried out with the push of a single button. Immediate condition evaluation, alarm generation, historical data, and trends – all delivered right on the screen.


Leonova Diamond is a dependable and highly potent analysis tool, addressing all of your condition monitoring needs. It offers a full and wide range of sophisticated measuring techniques as well as all the supporting diagnostic and troubleshooting capabilities. The instrument efficiently and reliably handles different machine characteristics and variable running conditions. State-of-the-art digital technology and careful software design enable superior data acquisition and processing. For use in hazardous areas and hostile environments, an intrinsically safe version is available.

Leonova Diamond offers highly sophisticated vibration measurement and shock pulse measurements with the patented HD technologies, providing razor-sharp spectrums even where signals are weak and low in energy content. The instrument’s excellent signal-to-noise ratio gives a decisive advantage where weak signals are present among stronger signals, such as in gearboxes.

Leonova Diamond is part of the Leonova line of portable instruments and sibling to Leonova Emerald®.


“We were looking for a supplier who could solve the specialized problems of our clients regarding slow turning machinery. We also wanted a software platform that was analysis friendly. But the most principal factor in our decision to buy the Leonova Diamond was the HD technology. It will allow us to provide better service for our clients.”

Leonova Diamond includes High Definition Shock Pulse Method (SPM HD®) for bearing condition and advanced three-channel vibration analysis for general machine condition and many more features, see below.

Bearing and lubrication condition

Note: Also read about HD ENV® (below) for bearing monitoring.

The SPM HD® method (HDm/HDc)

The SPM HD® method is a patented further development of the Shock Pulse Method (SPM) in being less sensitive to interference from other signals and therefore unique in its ability to measure from very low rpm (0.1 - 20 000 RPM range). SPM HD is used for fast, easy, and reliable diagnosis of the operation condition of rolling element bearings.

SPM Spectrum™

SPM Spectrum™ is based on extraordinary signal quality and 24-bit A/D conversion that provides razor-sharp resolution and helps determine where possible bearing damage is located with very high precision.


The original Shock Pulse Method is based on dBm/dBc that counts the rate of incoming shock pulses per second and provides one value for the shock carpet level and one value for the maximum level (peaks).


The LR/HR method was developed from the original Shock Pulse Method for condition diagnosis of rolling element bearings and allows a precision analysis of oil film condition in the rolling interface.

Vibration analysis

The HD ENV® technique

HD ENV® is a patented enveloping technique used for early detection of impact-related events such as gear and bearing damage. A number of predefined filters are available for easy selection; each designed to detect damages in different failure stages. The method utilizes cleverly engineered algorithms for digital signal processing to obtain optimal data for trending purposes.

Vibration severity plus FFT Spectrum

Measurement of vibration velocity, acceleration, and displacement (0-40kHz frequency range) according to the latest ISO 10816 standards helps to diagnose general machine condition. In addition to the RMS vibration readings, the instrument displays an FFT spectrum, where symptoms of imbalance, misalignment, and structural weakness are easily identified.

Three-channel vibration analysis

Three-channel vibration measurement allows you to study machine movement in three dimensions by observing the difference of the phase angles measured on the three channels. The three channels measure simultaneously, which means fast operation and rapid evaluation of assignments.


The EVAM (Evaluated Vibration Analysis Method) measuring technique produces up to 25600 line spectrum with true zoom, provides ready-made machine 'fault symptoms' as well as trending.

Journal bearings

Orbit analysis

For all machines with journal bearings, simultaneous measurement with two vibration transducers supplies an accurate graph of the shaft centre line movement.


Structural resonances

Run up/Coast down measurement and Bump test are tools for root cause analysis and show the machine frame vibration characteristics, resonance frequencies, and the reaction at critical speeds.

Corrective maintenance

Precision shaft alignment

For laser alignment of horizontal and vertical machines, the optional LineLazer Alignment Kit connects wirelessly to Leonova Diamond, and the user is guided through the alignment procedure to a perfect result.

Dynamic balancing

Field rotor balancing in single and dual plane according to ISO 1940-1 standard with an initial vibration measurement guiding the user through a balancing procedure with suggestions for correcting the imbalance.

HD Order Tracking

On machinery operating under variable speed, vibration analysis with HD Order Tracking provides reliable data and crystal clear measuring results even when RPM varies greatly during the course of measurement. Order Tracking is applicable in a very wide RPM range, from just a few to thousands of revolutions per minute.
