The main function
■ Monitoring and protection of bearing vibrations of rotating machinery such as steam turbines, turbines, compressors, blowers, etc.
Technical indicators
■ Input signal: SZ-6 type magnetoelectric speed sensor, sensitivity: 50mV/mm/s ±5%, frequency response: 10~300Hz.
■ Display mode: 3-digit LED digital display, accuracy: ±1%.
■ Measurement range: 0 ~ 500μm (peak-to-peak amplitude), 0 ~ 30.0mm / s (vibration intensity) or user-defined.
■ Corresponding to the full-scale range linear output DC4 ~ 20mA analog signal, load resistance ≤ 500Ω, accuracy: ± 1.0%.
■ All parameters can be displayed or set on the display by pressing the button. The parameters that can be set or displayed mainly include: alarm value, stop value, historical maximum value after alarm, and measurement linear correction.
■ Alarm output: Alarm I, alarm II secondary alarm output, when the measured value exceeds the limit, LED light indication, relay action, relay contact capacity DC28V /2A, AC250V /1A;
■ Automatically save historical peak and historical alarm status after alarm, setting data and historical parameters can be saved for a long time after power failure.
■ With power-on and power-down suppression function (protecting historical data, suppressing false alarms), self-locking alarm output function within 30 to 45 seconds after power-on.
■ Environmental requirements:
* There are no corrosive, no strong magnetic fields, etc.;
*Usage temperature: 0~50°C;
* Storage temperature: -40 ~ 60 ° C;
* Relative humidity: 20 to 90% (non-condensing);
■ Power supply: Voltage AC220V±10%, frequency 50Hz, power consumption <10W;
■ Panel mounted instrument: Dimensions (width) 160 × (height) 80 × (deep) 225 mm3; opening size (width) 152 × (height) 76mm2, plate mounted
■ Wall-mounted instrument: Dimensions (width) 190 × (height) 290 × (thickness) 92 mm3; installation size (bottom) 170 × (height) 272 mm2 (equilateral triangle)
■ Instrument weight: Panel table: 1kg. Wall table: 3kg.
■ Refer to the random instruction manual for the system debugging and usage.
