● В основном используется в режиме реального времени для измерения радиальной вибрации вала ротора вращающегося оборудования. Выходной диаметр вала до вибрации. Раннее обнаружение, сигнализация и защита вращающихся механизмов, так что срок службы машины увеличивается, сокращается цикл технического обслуживания блока.
● High level of integration, no proximitor, high reliability
● MJ-VR9820 integrated the function of proximitor and the transmitter .MJ-VR9820 only need probe and extension cables. As MJ-VR9820 save the proximitor, making monitoring assembly further reduced, so the reliability is greatly improved.
● Install easily without any adjustment
● MJ-VR9820 is extremely easy to install, can be installed in the field or in the control room. The machine measured point: General requirements in the vicinity of the bearing installation of a X, Y two intervals of 90 ° MJ-VR9820 transmitter. For a standard double bearing rotating machinery, usually installed 4 sets of vibration transmitter. The parameters have been adjusted and calibrated in our factory. So customer just need to connect the right cables without any adjustments and calibration. MJ-VR9820 can connect with our company's 8mm eddy current sensor probe .
● Gap of eddy current sensor: Generally adjust GAP output to 10 ± 0.25V.
● Fault Monitoring: Monitoring of rotating machinery rotor shaft radial vibration.
● Measurement parameters: Radial vibration (displacement) of the peak to peak.
● Unit Type: Variety of sliding bearings of rotating machinery. Such as steam turbines, fans, compressors, motors, pumps and so on.
●Installation Requirements: MJ-VR9820 directly connect with the eddy current probe, extension cable.

Transmitter Dimension:
MJ-VR9820 vibration transmitter deal with the signal of peak to peak vibration displacement via the transmitter filter, peak to peak detection and normalization. Directly output 4-20mA signal to DCS, PLC interface for rotating machinery rotor shaft vibration monitoring. It provides a simple, low-cost way.
● Conditioning monitor:
Monitoring a rotor radial vibration, including shaft vibration and rotor swing etc..
● Measurements:
Measures unbalance, asymmetric, and loosen parts resulted in high vibration.
● Typical application:
Widely applied to vibration monitor of various rotary machines such as turbine, fan, compressor, motor and pump etc.
● Installation:
Need an additional eddy current proximity probe and an extension cable to build a measuring system, and the system should be installed on safety site.
