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

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 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).

Pulse oximeters are devices that monitor the saturation of one's hemoglobin. A portable pulse oximeter is useful for those who need to monitor their hemoglobin while traveling.

The shock pulse method was invented in the late 1960s. In rolling element bearings, there is a phenomenon where electric waves, or elastic waves, or shock pulses, or impact signals, are generated. The amplitude of these impacts is determined by three different parameters.

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 

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

What is the Shock Pulse Method? Due to the sensitivity of the Shock Pulse Method, bearing lubrication condition is measurable through the signal monitored as dBc. The dBc is measured in the time wave signal of the shock pulse transducer. The filtered transducer signal reflects the pressure variation in the rolling interface of the bearing.

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

Shock pulse technology is generally well known to vibration analysts and reliability technicians. A handheld combination of sensor and display meter would
