Mainly used in online real-time measurement of radial vibration of rotating machinery rotor shaft. Output shaft diameter to vibration. Early detection, alarm and protection of rotating machinery, so that the machine's operational life lengthened, shortened maintenance cycle unit.
High level of integration, no proximitor, high reliability
YD9820 integrated the function of proximitor and the transmitter .YD9820 only need probe and extension cables. As YD9820 save the proximitor, making monitoring assembly further reduced, so the reliability is greatly improved.
Install easily without any adjustment
YD9820 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 u00b0 YD9820 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. YD9820 can connect with our company's 8mm eddy current sensor probe .
Gap of eddy current sensor: Generally adjust GAP output to 10 u00b1 0.25V.
monitoring of rotating machinery rotor shaft radial vibration.
radial vibration (displacement) of the peak to peak.
variety of sliding bearings of rotating machinery. Such as steam turbines, fans, compressors, motors, pumps and so on.
YD9820 directly connect with the eddy current probe, extension cable.
