Types of Vibration Sensors

Proximity sensors

These sensors are also called eddy current, displacement or distance sensors, and are used for measuring shaft movements and internal clearances in plain bearings.

For example, the vibrations of a drive shaft relative to slide bearings or other supporting parts can be measured.

Velocity sensors

Velocity sensors are used for monitoring vibrations and for balancing rotating machines.

This type of sensor has a lower sensitivity to high-frequency vibrations than accelerometers and is therefore less prone to overloading.


An accelerometer can be used for both high and low frequency vibration measurements. The sensor converts dynamic vibrations to a voltage.

These are full-contact sensors that are placed directly on the object to be measured, such as a bearing housing or gearbox.
