RDXZ-A02-B01-C01 Shaft Vibration Monitor
The monitor is matched with the eddy current sensor and is used to continuously monitor the radial vibration of the large shaft or rotor during the start-stop and operation of the rotating machine and output the analog current, alarm, and shutdown signals. The shaft vibration monitor is a smart meter. Easy to connect with DCS, PLC system, paperless recorder.
The main function
Radial vibration monitoring and protection of rotating machinery such as turbines, turbines, compressors, blowers, etc.
1. Display function
Vibration measurement value, I value alarm, II value alarm setting value, can be displayed on the LED digital tube.
2. Alarm function
With alarm protection function, when the vibration amplitude exceeds the alarm or stop set value, the alarm or stop indicator is on, and the switch signal is output at the rear panel to protect the monitored equipment.
3. Alarm delay time setting function
Alarm delay time adjustment range is 0~3 seconds to prevent false alarms caused by on-site interference.
4. Self-diagnosis function
Any input system failure, such as probe wear, poor wire contact or breakage can be detected, and power off alarm and shutdown.
With power-on, power-off detection function, and shutdown alarm and shutdown output circuit at the same time, it can effectively inhibit the monitor from false alarm.
5. Output interface
With current output interface, it can be connected with computers and other devices.
Technical indicators
Input signal: 8mm eddy current sensor system, linear range: 2mm sensitivity: 8mV/μm, frequency response: 0～5KHz.
Measuring range: 0 ~ 200μm, or user-defined, accuracy: ± 1.0% of full scale.
Display method: Three and a half LED digital display, resolution 1μm.
Current output 4 ~ 20mA analog signal, load resistance ≤ 500Ω, accuracy: ± 1.0%.
Alarm output: LED flashing, relay action, relay contact capacity DC28V/2A, AC250V/1A.
DC-24V voltage output for powered eddy current sensors.
Failure indication: When the input signal is abnormal, LED failure indication and block alarm output.
By pressing the key to display or set parameters on the display, the parameters that can be set or displayed include: alarm value, stop value, alarm delay time, current linearity correction.
Automatically save historical peak value and historical alarm status after alarm, set data and history parameters can be saved for a long time after power failure.
With power-on and power-down suppression (protect historical data, suppress false alarms), self-locking alarm output function within 30 to 45 seconds after power on.
Environmental requirements:
No corrosion, no strong magnetic field, etc.
Use temperature: 0～50°C;
Power Source: AC220V±10%; frequency 50Hz; power consumption <10W.
In order to ensure that the system's linear working eddy current sensor system must be matched to the following: probe specifications (such as Ф8mm), probe and extension cable system length (such as 5m, 9m), according to the selected probe specifications and cable system length to confirm the front device specifications.
※ The installation method of the probe, the debugging and use of the system refer to the random operation manual.
※ In order to facilitate on-site installation and commissioning of shaft vibration or eccentric measurement probes, our company specially designed QRD and HRD measuring rods for selection. For ordering methods, please refer to “Selection Data of Sensorsâ€. Storage Temperature: -40～60°C ;
* Relative humidity: 20 to 90% (non-condensing).
