BENTLY NEVADA 3300/65-03-01-00-00-00-01 VIBRATION DUAL PROBE MONITOR

BENTLY NEVADA 3300/65 - 03 - 01 - 00 - 00 - 00 - 01 is a vibration dual-probe monitor, which belongs to the 3300 series monitoring system of Bently Nevada Corporation. The following is its relevant introduction:

Functional features

Signal integration measurement: The shaft relative displacement signal from the Bently Nevada proximity sensor and the housing vibration signal from the speed sensor installed on the same shaft can be integrated to obtain the measurement result of the absolute vibration of the shaft, which can fully reflect the vibration state of the rotating equipment.

Multiple measurement functions: Provides four different measurement values, including shaft relative vibration (proximity probe measures the vibration of the shaft relative to the bearing seat), bearing seat vibration (seismic measurement of the vibration of the bearing seat relative to free space), shaft absolute vibration (the vector sum of the shaft relative vibration and the bearing seat vibration) and the average radial position of the shaft relative to the bearing clearance (DC clearance measurement of the proximity probe).

Technical parameters

Full scale range: According to the code in the model, "03" here means the full scale range is 0 to 15 mils (mil, 1 mil = 0.0254 mm).

Relative sensor input: "01" means using 3300 or 7200 Proximitor® sensor input.

Input impedance: 10 kΩ.

Power supply: Typically - 24 Vdc.

Power consumption: Nominal power consumption 1.5 watts.

Output: Such as recorder output can be in the range of + 4 to + 20 mA, which is proportional to the full scale of the programmed monitor.

Application scenario

Mainly used for large mechanical equipment with fluid film bearings, such as large steam turbines and gas turbines, etc., the vibration of the shaft in these equipment will be transmitted to the casing in large quantities. The monitor can effectively monitor the vibration condition of such equipment, provide important basis for equipment maintenance and fault diagnosis, and ensure the safe and stable operation of the equipment.
