Vibration sensors, also known as piezoelectric sensors, are versatile tools for the measurement of various processes. These sensors use the piezoelectric effect, which measure changes in pressure, acceleration, temperature, strain or force by converting them to an electrical charge. A vibration sensor can also be used to determine aromas in the air by simultaneously measuring resonance and capacitance.
Vibration sensor devices are ideal for measuring the amount and frequency of vibration in machines or equipment. The measurements can then be used to detect and monitor certain issues like imbalances to help highlight future breakdowns in the machine. The range of vibration can vary greatly so you should always specify vibration sensors to measure the maximum vibration range of your application.
Accelerometers measures acceleration but not necessarily vibration. However, vibration sensors can measure a quantity of acceleration and for this reason are a type of accelerometer.
