Shock Pulse Monitoring also known as SPM is a patented technique of predictive maintenance by measuring vibration and shock pulses of bearing in motors and to identify their condition and operating life before the next overhaul procedure.

2022/08/26 · Shock pulses are defined in the test standard and are classified as either a classical shock pulse or a transient representation of a recorded real-world event. Although most classical shock pulses are defined in terms of acceleration, the main purpose of a shock test is to generate a delta-velocity and then inspect the effects of the delta-velocity on the product.

Shock pulse transducers can be used in permanent SPM installations for bearing monitoring. They are installed in countersunk mounting holes on the bearing housings. A shock pulse transducer converts the shock pulses emitted by the bearing into electric signals.

Methods and signal forms in vibration & shock pulse analysis. The best bearing ultrasound detector. SPM HD: the best way to detect bearing and gearboxes failures, even at very very low speed.. FFT analysis: often used for identifying the most common machine faults, such as misalignment or unbalance.. Order analysis: Variant of FFT analysis used for machines with variable RPM; instead of the

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 

The form of the shock pulse and particularly the pulse duration are equally important. For example, a short 1 ms 300 g shock has little damage potential and is not usually of interest but a 20 ms 300 g shock might be critical. Monitoring of goods in transit. Shock loggers can be used to monitor fragile and valuable goods during transit and

SPM is an abbreviation for the Shock Pulse Method, which is a patented technique for using signals from rolling element bearings as the basis for efficient condition monitoring of

Features of dBm/dBc Shock Pulse Monitoring. Easily understandable condition evaluation in red-yellow-green scales. Easy, fast and reliable diagnosis of bearing condition. Verifies the source of high shock pulse readings when used with SPM Spectrum. Bearings generate shocks in the interface between the loaded rolling element and the raceway

The module collects the two most important parameters for machine condition analysis: Vibration Velocity and Shock Pulse. 750-645 Vibration Monitoring 

The instrument is push-button controlled and basic measurement data are entered manually. BearingChecker measures shock pulses, either with a built-in probe (BC200) or with an external transducer. The instrument can also be used as an electronic stethoscope for detecting machine sound irregularities. Measuring results are indicated by green

Shock pulse amplitude is due to three basic factors: Rolling velocity (bearing size and rpm) Oil film thickness (separation between the metal surfaces in the rolling interface). The oil film depends on lubricant supply and also on alignment and pre-load. The mechanical state of the bearing surfaces (roughness, stress, damage, loose metal particle).

The shock response spectrum is the peak absolute acceleration response of each SDOF system to the time history base input.3As an alternative, this function can be represented in terms of its peak positive and peak negative responses. The dimensions are peak response (G) versus natural frequency (Hz).

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.

Step 1 - Amplification. Shock Pulse signals are relatively small in amplitude and do not travel great distances. To amplify the small Shock Pulse signal the piezo electric crystal stacks, which are the actual element in an. accelerometer that generates signals, are constructed in such a fashion that they are excited by the 36 kilohertz.

09/30 · Shock pulse analysis When a bearing has a lubrication problem or an incipient failure, it starts to emit ultrasound. Historically, the structure-borne ultrasound generated inside bearings and gearboxes have been called “shock pulses,” and the technology able to detect this type of signal has now reached an incredible level of reliability.

Officially, and accurately, it is a technology relying on the physical principle that sound travels undiminished through metal objects for great distances. The
