Overview

Zero speed monitoring device, equipped with vibration speed sensor, can measure the amplitude of bearing vibration of various rotating machinery, monitor the vertical and horizontal vibration of rotating machinery, especially suitable for machines with ball bearings. In such machines, the vibration of bearings can be transmitted to the casing for continuous measurement and protection of rotating machinery. Special attention should be paid to the installation of sensors to avoid reducing the amplitude of the sensor, changing the frequency effect, or generating signals that cannot represent the true vibration of the machine. This monitoring device is particularly suitable for situations where a large number of vibration points need to be measured, such as motors, compressors, fans, centrifuges, etc.
