Description

Piezoelectric velocity sensor is mainly used for measuring vibration velocity of shells.It mainly measures the absolute (relative to free surface) vibration of bearing housing, shell or structure. Unlike traditional magnetoelectric velocity sensors. It adopts crystal form. Specialized design based on piezoelectric accelerometer, embedded intergrator. Because of its adoption of crystal circuits, no moving parts,there will be no abrasion and ageing, It has long service life and can be installed vertically, horizontally or at any angle. The sensor is made of stainless steel shell,ICP type enhanced anti-jamming design, is applicable to all rotating machinery equipment with poor industrial environment. Broad-frequency design enables the piezoelectric velocity sensor to contain almost all rotating speeds and its higher harmonics. High performance enables it to be applied to all industrial field rotating machinery.
