Vibration and sound measurement services work to ensure public and private safety and comfort. These companies provide professional mitigation and control systems to ensure the best results. Here are some key terms regarding this service.
Axial – These are the most commonly measured vibrations and are usually measured in an orthogonal arrangement. They are divided into three axes. They measure up and down, sideways, and front to back. They are placed carefully at prescribed distances around a structure so they can measure multiple areas.
Torsional – These occur in rotating machinery like engines and turbines. Extraneous movement in these systems can be detrimental to this equipment, leading to failure. Strain gauges and telemetry equipment measure torsional stresses.
Chart Recorders – These devices record mechanical or electrical input upon a piece of paper. They use different color pens for different inputs. When a measuring instrument communicates with the chart recorder electronically it may record the result onto circular or strip charts.
Accelerometer – This is a mechanism that measures proper acceleration of a test mass that is on a stable frame. This is a measurement of weight, not actual speed. Accelerometers are often used to determine the changing environment around stable, large objects like buildings. They can also determine speed, seismic activity and dynamic distance without gravity.
Strain Gauges – This is a sensor that measures the resistance of applied force. It uses pressure, tension, weight or force and converts it into an a change in electrical resistance. This can then be measured. These are often used in the analysis of fatigue studies.
Noise Measurement Tools – These are used to measure the spectral frequency levels in local areas. This has residential, industrial and commercial applications and may lead to the installation of sound barriers and insulation.
Many things such as machines, equipment, and even traffic make vibrations. Vibrations, which are rapid linear motions, can have negative impacts on expensive equipment and surrounding environments. Before purchasing large machines and tools, many companies decide to hire a vibration measurement service to detect produced vibrations and offer solutions on vibration reduction and control.
These services use state-of-the-art tools, such as transmitters, sound sensors, and meters. Companies can also opt to buy their own products, such as portable, handheld vibration meters, to conduct the research themselves. They buy from manufacturers that make and sell products to aid in fluid mechanics, strain and stress measurements, calibration, vibration isolation, and acoustic analysis. These are often needed in industrial equipment environments, like in the construction industry and more.
Services that provide these offerings can come out to your place of business to test shock damage due to excessive vibration. They can then provide full reports about what they find, and help your business make an informed decision about workplace conditions. A company can also predict what types of vibrations will occur with a new roadway due to traffic, or the effects of vibrations on a new building being constructed.
Many engineers are involved in vibration testing and analysis as well, using their expertise to monitor such conditions with special machines and tools. Vibration monitoring experts will visit a construction site to provide on-site consulting regarding vibration testing, giving the client a better understanding of the dynamic motion of the equipment in question.
From monitoring the effects of shocks to providing analysis of conditions, vibration measurement services are valuable for several types of companies.
