VB-Z430F Wall mounted Bearing Vibration Monitor

VB-Z430F Wall mounted Bearing Vibration Monitor

The bearing vibration monitoring device has two independent channels that work independently, display independently, and can simultaneously receive signals from two vibration velocity sensors. It is used to continuously monitor and measure the peak to peak amplitude or vibration velocity (intensity) values of various rotating machinery bearings.

The measurement and protection control of bearing vibration in large rotating machinery (such as steam turbines, compressors, motors, fans, pumps, etc.) that can be widely used in the power, metallurgy, petrochemical, and paper industries.

2、 Technical parameters:

6. Display accuracy: ± 1% of full scale

7. Output method:

Constant current: 4-20mA

Alarm and danger switch quantity (AC250V/5A, DC27V/2A)

8. Environmental temperature: -10~60 ℃ (relative humidity: ≤ 80%)

9. Power supply voltage: AC220V/50Hz ± 10%

10. Installation method: Wall mounted

11. Appearance dimensions: 240 * 190 * 92 (mm)

Hole size: 275 * 170 (mm)

Function Description:

1. Display the vibration measurement value, I value alarm, and II value alarm set value, which can be displayed separately on the LED digital tube.

2. Alarm function: When the vibration intensity exceeds the alarm set value, the alarm indicator light will turn on, and at the same time, a switch signal will be output on the rear panel to protect the monitored equipment.

3. Alarm delay time setting function: The alarm delay time adjustment range is 0-9 seconds to prevent false alarms caused by on-site interference.

4. The self diagnostic function has the ability to detect power on and power off, and disconnect the alarm output circuit, which can effectively suppress false alarms of the instrument.

5. The output interface is equipped with a current output interface, which can be connected to devices such as computers, DCS, PLC systems, and paperless recorders.
