ZJS-4 four channel swing monitoring device

1、 Overview

Zjs-4 intelligent vibration swing monitor is a four channel intelligent digital instrument with single chip microcomputer as the core processor. The instrument is connected with the eddy current displacement sensor and can monitor the radial vibration of the main shaft of the water turbine generator set in X and Y directions on-line; Connected with low-frequency vibration sensor, it can monitor the vibration of vertical and horizontal channels online. Provide real-time vibration and swing monitoring signals for water turbine generator units
