A vibration sensor is a device that detects and measures the vibration of an object or system. It is commonly used in various applications, including structural health monitoring, machinery condition monitoring, and earthquake detection. In this article, we will explore what a vibration sensor is, the problems it solves, applications that use it, technical data, and the main manufacturers.

What is a Vibration Sensor?

A vibration sensor is an electronic device that measures the vibration of an object or system. It typically consists of a piezoelectric sensor or accelerometer that converts mechanical motion into an electrical signal, which can be analysed and processed to determine the level and frequency of the vibration.

Problems Solved by Vibration Sensors:

Vibration sensors solve a range of problems in various industries. In structural health monitoring, vibration sensors are used to detect and monitor changes in the vibration of buildings, bridges, and other structures, helping to identify potential damage or safety issues. In machinery condition monitoring, vibration sensors are used to monitor the health of machines, such as pumps, motors, and turbines, detecting abnormalities that could indicate mechanical problems or failures. In earthquake detection, vibration sensors are used to detect and measure seismic activity, helping to provide early warning of potential earthquakes.
