Product Details

JM-B-3ZD Intelligent Vibration Monitor is a new generation of intelligent dual-channel vibration monitoring instrument. It is mainly used to monitor the vibration of industrial rotating machinery equipment due to rotor unbalance, misalignment, loose parts, rolling bearing damage, gear damage, etc., such as casing vibration, bearing bush vibration, frame vibration, etc. At the same time, it can also monitor the relative vibration of rotating machinery, such as shaft vibration, swing, etc., and output the vibration intensity and amplitude data. JM-B-3ZD intelligent vibration monitor can accept signals from non-contact eddy current sensors, piezoelectric vibration velocity sensors, piezoelectric acceleration sensors, magnetoelectric vibration velocity sensors, etc. At the same time, it has the interface capability of data communication with various external systems (PLC system, DCS system and BAS system, etc.), such as: 4 ~ 20mA analog output interface, two-stage switch output interface, total alarm danger output interface, RS485 Digital communication interface and TDM real-time buffer signal output interface, etc., to meet the measurement requirements of different industrial field equipment. JM-B-3ZD Intelligent Vibration Monitor is completely digitized, with good stability, high accuracy, man-machine friendliness, convenient and reliable maintenance.
