XDG3222Y-axis vibration monitor

XDG3222Y-axis vibration monitor

The bearing vibration of large rotating machinery such as steam turbines, water turbines, generators, compressors, fans and pumps shall be monitored and protected.


The shaft vibration monitor is mainly applicable to power generation, steel, metallurgy, chemical industry and other fields. It can continuously monitor and measure the bearing vibration (relative vibration of shaft to bearing) of various rotating machinery, so that users can analyze and maintain the working conditions of the machine. The instrument is equipped with 4~20mA current, relay switching output, RS485 interface MODBUS-RTU communication protocol, which can easily form an automatic control system and monitoring protection system with DCS, PLC, PC, etc; The instrument adopts high-performance ARM processor and simultaneously monitors vibration amplitude and gap voltage value of eddy current sensor. It has good stability, high accuracy, friendly and beautiful interface, simple operation, convenient and reliable maintenance, and is at the leading level in China.

Our product portfolio

  • 1. The shaft vibration monitor takes the advanced ARM high-performance embedded processor as the core, and adopts professional signal conditioning and filtering circuits. The linearity, frequency response, temperature drift and anti-interference ability of the instrument measurement have been greatly improved, making the system measurement accuracy higher and the protection action more reliable

    2. It can simultaneously monitor the vibration value of rotating machinery and the output voltage value of eddy current sensor

    3. The configuration mode is flexible, and the working mode and parameters of the instrument can be configured and set by the upper computer software configuration or by pressing keys and touch screen

    4. Dual channels can work independently or single channel can be used through configuration instrument

    5. The parameters of the instrument can be viewed or set locally. Including: meter number, baud rate, calibration mode, channel status, small signal removal, alarm reset mode, range, alarm set value (alarm I value, alarm II value), alarm delay value, (4~20) mA corresponding range, etc

    6. Peak memory and setting parameters can be stored for a long time after power failure

    7. It has power-on and power-off suppression function (protection of historical data, suppression of false alarm), and self-locking alarm output function within about 5 seconds after power-on

    8. RS485 communication interface and general MODBUS-RTU communication protocol realize the network communication and remote control functions of the instrument
