●YD-500 series monitoring system，providing reliable machinery operating information for the turbo generator, blower, compressor and other large rotating machinery, such as: shaft vibration, tile vibration, displacement, eccentric, expansion difference, rotational speed, zero rotational speed, etc.
●YD-500 series monitoring system design conform to API670（Third Edition）standard，it can continuously measure and monitor the operational status of the machine. For early detection of machine failure，for example：providing important information for imbalance、bearing failure、misalignment,、shaft cracks.
●YD-500 rotating machinery monitoring system uses a frame modular structure, SMD components are used inside, which reduce power consumption and failure rate, reducing instrument size, saving users’ installation space. What is more important, the monitoring system are split frame design, it is user-friendly maintenance and debugging.
The greatest feature of YD-500 monitoring system mechanical structure is frame modular design，with reversible panel and convenient operation method for field adjustable alarm setting.
●YD-500 framework instrument is consisting of 7 monitoring unit. Which is equipped with a main power supply, a dual-channel rotational speed monitoring unit，two dual-channel axis vibration monitoring unit , two dual-channel shell vibration monitoring unit 、one dual-channel axial displacement monitoring unit.
YD500 Framework Instrument Composition：
◆Power Source YD-520
(Above configurationis the necessary unit for framework instrument, below is the optional unit.)
◆dual-channel shell vibration monitoring unit YD-540
◆dual-channel axis vibration monitoring unit YD-550
◆dual-channel axial displacement monitoring unit YD-560
◆dual-channel expansion difference monitoring unit YD-560A
◆dual-channel rotational speed monitoring unit YD-570
◆sigle-channel eccentric monitoring unit YD-580
◆dual-channel thermal expansion monitoring unit YD-590
Each monitoring unit applying sideway form insert into chassis.Rear of the chassis is the output and relay components,
User can operate the monitor without machine out of service by open the panel.
