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 a possible bearing damage is located with very high precision.

dBm/dBc

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).

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.
