Vibration intensity monitoring instrument

1. Introduction

The HZD-W/L intelligent vibration monitoring instrument is a precision intelligent measurement and control instrument widely used in departments such as power, petroleum, and chemical engineering. By using magnetic electric speed sensors, continuous monitoring and measurement of the peak to peak vibration or vibration velocity of rotating machinery bearings such as steam turbines and fans can be achieved. There is a current output proportional to the measured value, which can be directly connected to DCS, PLC systems, and paperless recorders. When the vibration amplitude exceeds *, it can automatically provide alarm relay switch value contact output.
