What is Vibration Testing?Metravi Instruments
Vibration testing and data promotes a better understanding of machine health, efficiency and better productivity, estimates & operating schedules. By compiling and collating data of any machine’s lifetime of wear and stress into a short period of time, vibration testing helps by providing insights to the working status and condition of machines, structures and even products.
How does vibration testing help?
Vibration testing is done by replicating conditions (under a test environment) that a product, machine or structure might go through or see in its lifetime, including conditions during transit as well as operations. Hence, vibration testing pre-empts performance issues and potential failures even before they start or occur.
Also, industries having 24-hour production cycles need critical vibration testing and monitoring processes and systems. In production-intensive industries like Oil & Gas, Power Generation, Metals & Mining, etc., failure or downtime of any machinery or device leads to loss of efficiency & higher production costs and an unsafe working environment too. Hence, these industries need continuous and regular vibration monitoring and testing.
Vibration testing and monitoring helps
- in detecting early warning signs for imminent machine failures.
- to increase maintenance intervals. If machine health is tracked regularly, maintenance can be scheduled as per need & not depending on hours of operation.
- in saving costs and making machinery reliable, as there are fewer unexpected failures.
- promote safety as when operators have insight into machine health, they are able to take faulty equipment offline before any accident or catastrophe occurs.
- by providing data that promotes a better understanding of machine health, efficiency and better productivity, estimates & operating schedules.
- manufacturers by ensuring reliability, durability and end quality of their products and components – by testing the shock and stress which the product can handle within the service life.
What is a Vibration Meter or Tester?
A Vibration Meter or Vibration Tester is an electronic instrument that can process vibration signals using a sensor which generates a voltage signal from the vibrations it senses when in contact with machines. These signals are transmitted to the instrument through a cable and used to measure the Being a measure of the rate at which velocity changes, accel...

More of the machine and displayed with high precision on the meter. Most of these meters can record these data over time with built-in data loggers and even present analytic reports from data over time.
Portable and hand-held Vibration Testers are easy to use for vibration testing and analysing, do not require extensive training and come in very handy to monitor and diagnose issues or problems with bearings, engines, pumps and other machines and machine components. They assist in machine condition monitoring, product testing and quality assurance.
These instruments help maintenance and quality engineers who are on the ground, to perform quick and easy vibration tests and analysis and assist by helping them check equipment condition and investigate problems while the machines are still working and running, which in turn helps in preventing downtimes by detecting early warning signs and imminent failures.
Metravi Portable and Hand-held Vibration Meters and Testers provide reliable and dependable ways to check machine health with high-accuracy on the go.
