The SPM meter measures the shock pulses per second and then lowers its threshold so that two amplitude levels are discovered, first the decibel carpet value of 

2003/11/02 · SPM stands for shock pulse monitoring. The term “shock pulse” describes what is produced when a ridge or asperity from one surface contacts a ridge or asperity of another surface when the lubricant film, designed to separate those surfaces, is lost. The pulse is a high-frequency signal that is collected with a sensor tuned to measure noise

Condition based maintenance on board, vibration & shock pulse monitoring. ANDERS HEDLUND. VIKTOR FORSLIN. Department of Shipping and Marine Technology.

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 LR/HR method was developed from the original Shock Pulse Method for condition diagnosis of rolling element bearings. It allows the precision analysis of

These mechanical shocks are elastic waves that mirror the impact-contact-force's time function and the Shock pulse monitoring accelerometer, which is tuned to

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

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

The SPM HD Shock Pulse Monitoring is a further development of Shock Pulse Method (SPM); which can be used for easy, fast and reliable diagnosis of the 

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.

Since the incorporation of our organization, we are offering Shock Pulse Monitoring System to our clients. This is apt for shock pulse measurement.

05/13 · 720.48 Shock pulse measurement Bearing, pump end M8 - 720.49 Shock pulse measurement Bearing, drive end M8 M8 for countersinking Ø 30 mm 1.6 Measuring nipple Suitable measuring nipples can be delivered on request. 1)

03/24 · Your machines contain rotating rolling bearings that create shock pulses during operation. These pulses indicate the condition of your machine. By using Shock Pulse Monitoring (SPM), we measure and trend this data. Ultimately, this makes it possible to predict machine failures and avoid breakdowns. NOTE: Your machines are not equipped with SPM

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