shock pulse meter calibration

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.

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.

As these shocks 'ring' the shock pulse transducer, it outputs electric pulses proportional to the shock magnitude. Unlike vibration transducers, the shock pulse transducer responds at its carefully tuned resonance frequency of about 32 kHz, thus allowing a calibrated measurement of the shock pulse amplitudes.

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

shock calibration of accelerometers. These are described in ISO 16063-22 [1]. The shock methods are applicable for amplitude range from as low as 10 G to above 10,000 G, and a pulse duration range of less than 0.1 ms to 8.0 ms. This report describes a system newly designed to facilitate shock calibration,

ISO 16063-22 specifically describes instrumentation and procedures to be used for secondary shock calibration of accelerometers, using a reference acceleration, velocity or force measurement for the time-dependent shock comparison. 4 The methods are applicable in. a shock pulse duration range of 0.05 to 8.0 ms, and a dynamic range (peak value

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.

This system can perform calibration and linearity checks up to 10,000 g and is one of the most versatile anvil shock-type devices available for shock calibration in terms of amplitude range,

Digital vibration transducers (DTI) and sensors with a DTI interface can also be calibrated using a sin² pulse. Primary calibration shock sensors

Bearing check and control are efficiently performed by the shock pulse method. The portable device BALTECH VP-3450 is designed to control a vibration level of rolling element bearings and lubricant condition in a bearing assembly. A bearing condition is evaluated by a color scale: green- good, yellow- warning, red- defect. View Product.
