1、 Overview
The intelligent vibration pendulum monitor is a dual channel intelligent digital instrument with a single chip microcomputer as the core processor. The instrument is connected with the eddy current displacement sensor to monitor the radial vibration of the main shaft of the hydro generator unit in X and Y directions on line; Connected with low frequency vibration sensor, it can monitor the vibration of vertical and horizontal channels online. The instrument has dual channel digital display, analog output and switching output.
