Vibration Sensors

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.

Who would use a piezoelectric sensor?

  • Medical industry
  • Engineers
  • Vehicle designers
  • Nuclear Technicians

Different types

  • Ohms rating differs for contact resistance
  • Various sizes are available
  • Maximum vibration reading can hit 29400 m/s²

What is the difference between a vibration sensor and an accelerometer?

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.

Things to consider when choosing a vibration sensor

  • Vibration range and sensitivity - General thinking is that if a machine produces high amplitude vibrations a low sensitivity sensor is better. If the vibration is less than 10 g rms, a 100 mV/g sensor should generally be used.
  • Frequency - important to know the frequency span you need to measure
  • Temperature - high temperatures can affect the performance
  • Exposure to chemicals or debris - contact can affect the reliability of the measurements and monitoring
  • Environment - hazardous atmospheres require specifically designed devices for use in dangerous areas
  • Where the vibration sensor is located - top exit, side exit or low profile are available
