Vibration Meter, seismograph vs SKF Values

Vibration meter is an app called seismograph or seismometer, which measures the strength of vibration, quakes, earthquakes, vibrations of the human body or any other objects around you. Our app allows for detecting and recording of seismic waves generated by earthquakes, volcanic eruptions, avalanches and other sources of vibration and shocks. Accelerometer in your mobile phone is used for detection of vibrations and measurement analysis. Graph presents a record of the ground motion at a measuring point. Ground movement or an object is presented as a function of time in the three Cartesian axes, with the z axis perpendicular to the Earth's surface and the x- and y- axes parallel to the surface. Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. It measures the effects of an earthquake and it is distinct from the moment of magnitude. Richter Scale assigns a magnitude number to quantify the energy released by an earthquake. Peak Ground Acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an accelerogram at a site during a particular earthquake. In this app we use Instrumental Intensity Scale (developed by The United States Geological Survey) which maps peak ground acceleration and peak ground velocity on an intensity scale similar to the felt Mercalli Scale. These values are used to create shake maps by seismologists on around the world. Mercalli Intensity Scale distinguishes the following levels of vibration and impact damage: I. Instrumental - Not felt. Recorded by seismographs. II. Weak - Felt only on top floors of high buildings. III. Slight - Felt indoors, like a passing light truck. IV. Moderate - Windows, doors rattle. Like passing train. V. Rather Strong - Felt by all. Small objects upset. VI. Strong - Books off shelves. Trees shake. Damage. VII. Very Strong - Difficult to stand. Buildings damaged. VIII. Destructive - Significant damage. Trees broken. IX. Violent - General panic. Serious damage. Cracks. X. Intense - Most buildings destroyed. Rails bent. XI. Extreme - Rails bent greatly. Pipelines destroyed. XII. Catastrophic - Near total damage. This app allows you monitor and share the results of your measurements with other users. Measure and monitor all vibration and shocks using smartphone or tablet!

The Values app is designed to be used with the SKF Shaft Alignment Tool TKSA 71. Together, the TKSA 71 and the app form a measurement system that allows readings of many rotating machines to be made in an intuitive and easy way. The app reads and visualises the readings from the measurement heads, similar to the readings given by mechanical dial gauges. The system uses line laser to PSD technology that enables highly accurate and reliable shaft measurements. The TKSA 71 and its app communicate wirelessly via Bluetooth®. KEY FEATURES: • Virtual dial indicator visualises live measurement readings and enables easy and intuitive measurements. • Highest degree for customisation – The values app is the modern representation of highly accurate dial gauges with additional convenience features. Experts get the possibility to use the alignment system for highly customised alignments with more advanced calculations, supporting various types of applications. • Ideal for training – Learning the underlying principle of shaft alignments is often accompanied by using traditional dial gauges and manual calculations. The values app facilitates the measurements and helps students to focus on the alignment calculations. • Automatic measurement report – Automatically generated measurement reports give a structured overview of the measured values. The reports can be customized with additional notes, a machine picture and a signature. The report can easily be shared via email or cloud services. • Easy to follow explanatory videos – Comprehensive videos show how to set up and perform accurate measurements with SKF Shaft Alignment Tools. • Machine library and QR code scanner – Helps keeping track of the machines that have been measured. Machine information like distances, the machine picture, and other details are saved for each machine and can be reused the next time the same machine is measured. QR codes can be scanned to identify a machine and quickly retrieve its details. The library can also be used for easy access to all the reports generated for each machine in one place. HARDWARE – SKF Shaft Alignment Tool TKSA 71: The SKF TKSA 71 system uses a pair of measurement units that are combined laser transmitter and detectors to measure and correct shaft alignment with high accuracy and reliability. The data is transferred in real time through Bluetooth® 4.0 LE to the app. IMPORTANT NOTE: This app is designed to be used with the SKF Shaft Alignment Tool TKSA 71 hardware. The SKF TKSA 71 can be purchased separately from your local SKF Authorized Distributor. For more information and technical specifications about the SKF Shaft Alignment Tool, please visit our website.
