The global vibration sensor market size was valued at USD 5.04 billion in 2020, and is expected to expand at a compound annual growth rate (CAGR) of 6.5% from 2021 to 2028. Vibration sensors are devices that detect vibrations and convert them into an electric current. These systems are being increasingly adopted as the need for machine condition monitoring and maintenance is growing. In recent years, vibration systems have been extensively used for monitoring the condition of machines, bridges, and buildings, and the prediction of natural disasters, which has driven the growth of the market. The growing demand for predictive maintenance in rotating machinery, including pumps, motors, bearings, and turbines, among others has further fueled the market.
