General Information

SPM Instrument AB is ISO 9001 certified, with technical data subject to change without notice. The company focuses on reliability and ease of use in its range of condition monitoring instruments and accessories.

Overview of Shock Pulse Method (SPM)
The Shock Pulse Method (SPM) has been used for over 30 years to diagnose rolling element bearings. It detects shocks generated by bearings using an SPM transducer, which outputs electric pulses proportional to the shock magnitude. The transducer operates at a resonance frequency of about 32 kHz, allowing for calibrated shock pulse amplitude measurements.

Measurement Process
The shock pulse meter measures the rate of incoming shock pulses per second and adjusts the measuring threshold to determine two amplitude levels: the shock carpet level (dBc) and the maximum level (dBm). The shock pulse amplitude is influenced by rolling velocity, oil film thickness, and the mechanical state of the bearing surfaces. Input data such as rpm and shaft diameter help neutralize the effect of rolling velocity.

Evaluation and Technical Data
Initial values and condition zones (green, yellow, red) are established empirically. The height of the carpet value and delta (dBm minus dBc) indicate lubrication quality or installation issues. Technical specifications include a measuring range of –9 to 99 dBsv, resolution of 1 dBsv, and accuracy of ± 1 dBsv. The output includes maximum value dBm, carpet value dBc, and audible shock pulse signals.

LR/HR Method
The LR/HR method, derived from the original SPM, provides precision analysis of oil film condition and calculates optimal lubricant. It requires precise data on bearing geometry, size, and speed. The method outputs include LR and HR raw shock values, a general bearing condition (CODE), oil film condition (LUB), and surface damage (COND).

SPM Spectrum
The SPM Spectrum verifies the source of high shock pulse readings through pattern recognition. It uses a Fast Fourier Transform (FFT) to produce a spectrum for pattern recognition. The evaluation is based on dBm or HR values, with alarm levels set manually for symptoms.

Vibration Measurement (ISO 2372 and ISO 10816)
Leonova offers vibration measurement according to ISO 2372 and ISO 10816 standards. ISO 2372 is a platform function for broad band vibration measurement, while ISO 10816 offers more flexibility in frequency range and recognizes various vibration parameters. Both standards categorize machine condition into green, yellow, and red zones based on vibration severity.

FFT Spectrum with Symptoms
This function provides vibration analysis by generating machine condition data, highlighting significant line patterns in vibration spectra, and trending symptom values. Users can select data types suited for individual machine surveillance.

It covers several key features including Evaluated Vibration Analysis Method (EVAM), two-channel simultaneous vibration monitoring, run-up/coast-down and bump tests, orbit analysis, and balancing.

1. Evaluated Vibration Analysis Method (EVAM):
EVAM is a method for analyzing machine conditions through vibration analysis. It generates condition parameters, vibration spectra, and machine-specific condition codes. Key parameters include RMS values for velocity, acceleration, displacement, crest, kurtosis, skewness, and noise levels. Spectrum analysis uses 'fault symptoms' for pattern recognition, with automatic configuration based on RPM.

2. Technical Specifications:
Frequency limits range from 0.5 Hz to 40,000 Hz, with various measurement windows and averaging methods. Spectrum lines can be extended up to 12,800, and different spectrum types (linear, power, PSD) are supported. Transducer types include SLD144 or IEPE (ICP®) with voltage output.

3. Two-Channel Simultaneous Vibration Monitoring:
This function allows for the observation of machine movement in two dimensions using two transducers. It requires identical parameter setups for both channels and uses a special measuring cable (CAB51). The system displays RMS values for displacement, velocity, and acceleration, with spectrum, phase spectrum, and time signal graphs available.

4. Run-Up/Coast-Down and Bump Test:
These functions analyze vibration during machine start-up or shutdown and assess vibration response at standstill. The run-up/coast-down test records RPM and RMS values, while the bump test uses a rubber mallet to measure vibration response. Technical data include frequency limits and spectrum lines.

5. Orbit Analysis:
Orbit analysis detects failures like rubs, unbalance, and misalignment in machinery with journal bearings. It requires two-channel simultaneous measurement and displays an orbit graph showing shaft movement. Settings include transducer type, signal unit, and filter type, with measurements made via buffered outputs or accelerometers.

6. Balancing:
