Vibration sensors or accelerometers are generally used in testing applications that require measurement of acceleration, vibration or shocks experienced by an object or a structure. They measure the acceleration in reference to Earth's gravity. The sensing element of accelerometer is an electromechanical device that behaves as a damped mass on a spring consists of a mechanical sensing element with a mechanism to convert the mechanical motion, such as displacement into electrical output. The sensing elements of the commercial accelerometers are typically made of piezoelectric, piezoresistive or capacitive materials.
Accelerometers are available in a wide range of models; charge-type piezoelectric or IEPE accelerometers with a wide range of frequency response for general vibration monitoring or condition monitoring applications, DC-response piezoresistive accelerometer for shock testing, automotive crash testing or blast testing, or highly sensitive variable capacitance accelerometers for automotive NHV (Noise, harness, vibration) testing, motion measurement and seismic testing. They can also be mounted in a drone and used as components of the inertial navigation system.
Bestech Australia offers a complete suite of vibration measurement sensors to support the condition monitoring program and testing requirements of almost all industrial and research applications. Our accelerometers have been widely used in university research laboratories and in industries such as defense and military, automotive, manufacturing, mining, aerospace, geotechnical, marine, and oil and gas. Examples of applications are Missiles and ballistic testing, aircraft flight test, seismic monitoring, automotive crash test, vibration monitoring in gas turbines and many other.
