YD9820 vibration sensors proximity YD9820 is a single channel shaft vibration transmitter, which consists of transducer, peak-peak value detector and normalized voltage and current. For radial vibration signal of a rotary machine, it provides an easy and lowcost resolution to interface of DCS and PLC. 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.
