The shock pulse meter counts the rate of occurrence (incoming shock pulses per second) and varies the gain until two amplitude levels are determined: HR = high rate of occurrence, quantifying the shock carpet (approx. 1000 incoming shocks per second). Calibration. The accuracy of the LR/HR method is increased by a calibration factor (COMP

The shock pulse meter counts the rate of occurrence (incoming shock pulses per second) and varies the measuring threshold until two amplitude levels are determined: The shock carpet level (approx. 200 incoming shocks per second). This level is displayed as dBc (decibel carpet value). The maximum level (greatest incoming shock under 2 seconds).

The Bearing Checker is a shock pulse meter based on the well proven SPM method for quick and easy identification of bearing faults. The instrument has a built-in microprocessor programmed to analyze shock pulse patterns from all types of ball and roller bearings and display evaluated information on the operating condition of the bearing.

Shock pulse method (SPM) is a technique for using signals from rotating rolling bearings as the basis for efficient condition monitoring of machines. From the innovation of the method in 1969 it has been further developed and broadened and is a worldwide accepted philosophy for condition monitoring of rolling bearings and machine maintenance

Shock calibration involves submitting the test sensor to different shock peak magnitudes. The following picture shows an example of a shock sensor being tested 

The various classical shock pulses have unique purposes. Generally, each of these unipolar pulses excites a wide range of frequencies in a short period of time but in different ways. Classical pulses are primarily defined in acceleration; the shape of the acceleration waveform determines the frequencies and the degree to which they are excited.

The Instrument, which reads the shock pulse DBM/DBC values and displays them as two numerical values is called the "IR-30". Any type of steel roller bearing can be monitored. The technology has no application to sleeve bearings. Data acquisition is a simple process. First, Decibel Initial value for the particular bearing(s) must be determined.

Piezoelectric accelerometers take advantage of the piezoelectric effect discovered by Pierre and Jacques Curie in 1880. They observed that certain materials, especially crystals and ceramic, would generate a charge or voltage in response to being stressed. They further saw that this response was linear with respect to the applied stress.

All shock pulse transducers are calibrated to behave exactly the same way when exposed to shock pulses. This means that the amplitude and the decay time are
