Product Details

Overview
VMS701 piezoelectric acceleration sensor is used in the vibration of key rotating machinery (relative to free surface) that requires the measurement of housing acceleration, such as displacement, velocity, acceleration, etc. It is more suitable for monitoring the damage of bearings or gearboxes. The integrated circuit technology (VLSI) and ICP-type enhanced anti-interference design adopted by the sensor make the sensor highly integrated, which greatly improves the stability and reliability of the sensor; it adopts crystal circuit, no moving parts, and no wear and tear and degradation. It has a long service life and can be installed vertically, horizontally or at any angle. The circuit is completely isolated from the shell, avoiding the noise problem caused by multi-point grounding that often occurs in the field. The wide frequency band design makes the frequency range of VMS701 piezoelectric acceleration sensor almost include the rotational speed of rotating machinery and its higher harmonics. High performance allows it to be applied to rotating machinery in harsh industrial environments.
