I. Overview

The JM-B-2VT dual-channel vibration monitor is a new generation of intelligent products based on the integration of sensor technology, new signal processing technology, interrupt technology, and human-computer interaction technology. It adopts a dual-channel synchronous monitoring mode to effectively monitor the operating conditions of the equipment, and extract relevant data for characteristic parameters, unit status data, and complete unit failure early warning and alarm. It can establish a set of rigorous vibration monitoring, diagnosis and analysis system for the equipment, by continuously monitoring the important state parameters of the equipment operation, understanding the operation status of the equipment in time, providing important data for the pre-diagnosis of accident signs, and providing reliable operation of the equipment Protection.
