Piezoelectric Velocity Sensor
A piezoelectric velocity sensor is designed for absolute vibration measurement using a fully sealed, isolated-ground structure that enhances signal integrity and reliability. With high integration accuracy and a low-impedance voltage output, it provides stable, noise-resistant performance in industrial environments. It is widely used for measuring the absolute vibration of bearing housings and structural shells in fans, motors, pumps, and other rotating machinery.
