Features

Leonova Emerald IS includes High Definition Shock Pulse Method (SPM HD®) for bearing condition and advanced vibration analysis for general machine condition and 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.

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.

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).

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 (0-20kHz 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.

EVAM

The EVAM (Evaluated Vibration Analysis Method) measuring technique produces up to 12800 line spectrum with true zoom, provides ready-made machine 'fault symptoms' as well as trending.

Corrective Maintenance

Dynamic balancing

Field rotor balancing in single 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, 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

Leonova Emerald IS 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 Emerald IS comply with the strictest ATEX/IECEx standards and thus can be used in zones 0 - 2.

Accessories

Transducers

Leonova Emerald IS can be used with vibration, shock pulse, or DuoTech transducers, designed to withstand the rigors of industrial and potentially hazardous environments. Read more about our transducers for explosive atmospheres.

The transducers are available in an array of mounting options: magnet foot, quick connector, or fixed installation – choose the version 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). It tolerates surface temperatures up to 110° C (230° F). The probe is rated 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 and +300 °C.

Headset with microphone

We also offer a comfortable headset (approved for use in potentially explosive atmospheres – zone 0 excluded) with a microphone for Leonova Diamond IS and Leonova Emerald IS, providing excellent sound reproduction even in noisy environments. The headset is equipped with a microphone for the 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 Emerald IS kit

This carrying case, made from the conductive material skai, is designed specifically for transporting measuring devices in explosive environments. The bag reliably prevents electrostatic charges and diverts 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. 

Dimensions: 37x20x27 cm (14.5x7.9x10.6 in).
