Leonova Diamond IS
Leonova Diamond IS is the most advanced ATEX/IECEx-certified instrument on the market. With three-channel vibration measurement and a large color display, it provides a unique combination of sophisticated technologies and usability in a single portable instrument.
Zone 0 - 1 - 2 compliance for advanced condition monitoring
The instrument is built to withstand harsh environmental conditions. Heavy industries with intrinsic safety requirements, such as the refinery, mining, or oil and gas industries, are challenging environments. The instrument complies with the strictest ATEX/IECEx standards and thus can be used in zones 0 - 2.
Maximum flexibility with vibration analysis and SPM HD
Leonova Diamond IS offers the strongest combination of measuring techniques available. Three-channel vibration measurement (DC to 40 kHz), HD Order Tracking, sophisticated analysis, and the SPM HD technique for condition monitoring of rolling element bearings (1-20 000 rpm range) provide maximum flexibility for detecting machine faults.
Sophisticated analyzer with scalable functionality
The instrument is an excellent choice where a full range of measuring techniques and high analytical power is required to monitor plant equipment.
Based on a scalable system, Leonova enables customized solutions where additional functionality can be added as required.

Features
Leonova Diamond IS 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 which provides razor sharp resolution and helps determine where a possible bearing damage is located with very high precision.
dBm/dBc
The original Shock Pulse Method is based on dBm/dBc which 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).
LR/HR
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.
EVAM
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 centerline movement.
Resonance
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
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.
Order tracking
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.
Technical overview
The intrument is lightweight, ergonomic, and easy to operate. Load measuring rounds to Leonova from the PC, then simply measure and save. All input data is pre-programmed. You get an instant condition evaluation on a green-yellow-red scale.
The instrument will deliver long working life under the toughest, most demanding circumstances. Leonova Diamond IS comply with the strictest ATEX/IECEx standards and thus can be used in zones 0 - 2.

Accessories
Transducers
Leonova Diamond IS can be used with vibration-, shock pulse- or DuoTech transducers suitable for explosive environments, designed to withstand the rigors of industrial environments. Read more about the transducers we offer for explosive environments.
The transducers are available in an array of mounting options; magnet foot, quick connector or fixed installation – choose what's most practical for your needs.
Handheld probe
The handheld shock pulse transducer with probe is perfect for use together with SPM's handheld Ex instruments in a potentially explosive atmosphere. The probe tip is spring loaded and moves within a sleeve made of chloroprene rubber (neoprene) and tolerates surface temperatures up to 110° C (230° F). The probe is classed IP65.
Combined tachometer and temperature probe
The tachometer and temperature probe for potentially explosive atmospheres is used for optical or contact measurement of the rate of rotation and for contact measurement of peripheral speed. It also has a built-in temperature sensor for measurements between −20 to +300 °C.
Headset with microphone
We also offer a comfortable headset (approved for use in potentially explosive atmospheres – except for zone 0) with microphone for Leonova Diamond IS and Leonova Emerald IS, providing excellent sound reproduction even in noisy environments. The headset is equipped with microphone for voice recording of comments to the measuring points. Connection cord made out of soft spiral polyurethane with a 6.3 mm stereo plug. An adapter must be used as the audio jack in the Leonova IS instruments is 3.5 mm. Choose between headset with headband, neckband or with helmet brackets.
Handy case for your entire Leonova Diamond IS kit
This carrying case, made from the conductive material skai, is specially designed for transporting measuring instruments in explosive environments. The bag reliably prevents electrostatic charge and divert already existing charges. The soft case comes with easily customizable modular inserts and is provided with a shoulder belt for easy and hands-free movement.
