Product Details

Overview
VMS601 piezoelectric speed sensor is mainly used to measure the vibration speed of the shell. Primarily measures the vibration (relative to the free surface) of a bearing housing, shell or structure. Different from the traditional magnetoelectric speed sensor, the sensor adopts the crystal form, which is optimized on the basis of the piezoelectric accelerometer and embedded with the integration circuit. Because it uses a crystal circuit and has no moving parts, there is no wear and degradation, a long service life, and it can be installed vertically, horizontally or at any angle. The sensor adopts a stainless steel shell and ICP type enhanced anti-interference design, which is suitable for rotating machinery in harsh industrial environments. The wide frequency band design makes the frequency range of VMS601 piezoelectric speed sensor almost include the speed of rotating machinery and its higher harmonics. High performance makes it suitable for industrial field rotating machinery.
