You can continuously monitor the vibration of rotating machinery with a roast!
The vibration switch VM-90A is designed to continuously monitor vibrations for the purpose of ensuring safety during the operation of various rotating devices such as turbines and blowers, detecting abnormal operations, identifying degradation phenomena, and facilitating early maintenance. It detects vibrations from turbines and blowers using a pickup and outputs a current signal proportional to the magnitude of that signal from the converter body. Additionally, it compares the signal level with a pre-set alarm value; if the signal level exceeds the set value and the delay time for alarm operation has passed, the alarm relay will activate. Despite its compact size, the VM-90A allows for the selection of vibration measurements for acceleration, velocity, and displacement.
