Vibration sensor
A vibration sensor is a device used to detect and measure vibration in mechanical systems, typically composed of sensing elements such as piezoelectric crystals or micro-electromechanical systems.
Application field
Vibration sensors are widely used in industries such as manufacturing, automotive, aerospace and construction, helping with predictive maintenance, fault diagnosis and performance optimization. By continuously monitoring vibration levels, these sensors can detect potential problems early on, preventing high downtime and maintenance costs.
Introduction to Sensors
Vibration sensors are widely used detection sensors. Their working principle is to sense the vibration parameters of mechanical motion (such as vibration velocity, frequency, acceleration, etc.) through the internal piezoelectric ceramic plate and spring weight structure, and convert these parameters into usable output signals. Then, these signals are amplified by the operational amplifier and output as control signals, thereby achieving the monitoring and measurement of vibration.
