what is shock pulse monitoring

The shock pulse method (SPM) has been widely used as a quantitative method for bearing condition monitoring. However, the shock value indicating 

A shock pulse transducer contains a reference mass (m) and responds with a dampened oscillation when hit by a shock wave. Attached to the reference mass is a 

Pulse pressure is the difference between the upper and lower numbers of your blood pressure. Pulse pressure tends to increase as you get older, and this number can also be an indicator of health problems before you develop symptoms. If you want to monitor your blood pressure on your own, blood pressure cuffs are available in most pharmacies

LEO232 SPM Spectrum (2). LEO233 ISO 10816 vibration monitoring with spectrum (1) Unlike vibration transducers, the shock pulse transducer.

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

12/16 · For those pieces of equipment that are so critical that periodic monitoring is not enough, then continuous monitoring needs to be considered. The Shock Pulse Method

11/22 · Take this opportunity to learn about the Shock Pulse Method directly from the source. This method was invented by SPM Instrument in Sweden in 1969 and has been widely

12/16 · Shock Pulse Phase. When two pieces of metal, in motion, contact each other two interrelated yet distinct processes occur. On initial impact a shock or pressure wave develops

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.

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 machines. Instant evaluation of bearing condition is given in an easily understood green-yellow-red color scheme.

Shock Pulse Monitoring A Snapshot Unless an individual is involved with some form of machinery vibration analysis, the term "Shock Pulse" (Monitoring) is unknown and somewhat

The Shock Pulse Method (SPM) is the front line technique the Hallsta paper mill chose to quickly manage input from its 800 rolls, with 4000 machines and 1 6,000 measurement points. With 8 inspectors, they need a quick method to know whether bearings need to be greased or not, or that damage is present and needs to be monitored more frequently.

02/27 · Shock Pulse Monitoring When two pieces of metal touch each other while in motion, stress waves develop from the impact which quickly propagates through the metal. This stress wave is what is measured to monitor the condition of rolling-element bearings.

Shock pulse measurement primarily serves the purpose of preventive maintenance of rolling element bearings. Regular measurements are used to monitor the installation, operating conditions (lubrication, loads, etc.) and the development of the lifetime expectancy (wear rate) of the bearings. These aim at making the best possible use of

SPM HD can be used to monitor applications in the 0.1 - 20 000 RPM range. Throughout their lifetime, bearings generate shocks in the interface between the loaded rolling element and the raceway. These shocks 'ring' the shock pulse transducer, which outputs electric pulses proportional to the shock magnitude.
