Bently Nevada 3300/61

Operating Parameters

Operating Temperature: In the normal operating range, the sensor typically operates at -30°C to 85°C. This temperature tolerance allows it to operate in many industrial environments, whether in hot furnace environments or cold outdoor installations.

Accuracy: Bently Nevada 3300/61 has very high accuracy in detecting shaft vibration and position. The sample error in the actual measurement may be ±0.05mm/s, so as to accurately detect the operating behavior of the machine. It has good accuracy in position measurement: the position measurement error is about ±0.025mm. This is ideal in situations where the actual position of the shaft must be accurately determined, including axial or radial deviations.

Fundamental Frequency: The fundamental frequency response range of Bently Nevada 3300/61 is designed to vary over a wide range, mostly from 2Hz to 10kHz. The wide frequency range enables it to detect low-frequency vibrations generated by slowly rotating machinery, as well as high-frequency changes that may be caused by mechanical resonance or high-speed phenomena.

Power supply: The power supply requirement is typically 18 to 30 VDC to ensure stable operation of the equipment for continuous operation. It is designed to be low-power, less than 5 watts - a good aspect for energy-saving applications in the industrial field.

Product Features

Monitoring and Measurement: Bently Nevada 3300/61 is primarily a real-time monitoring system for shaft vibration and position. It uses advanced sensing technology to continuously measure the vibration level of the rotating shaft. It is able to detect mechanical problems at an early stage, such as imbalance or misalignment, or even bearing wear or resonance, using vibration screening. For example, once the vibration amplitude exceeds a preset threshold, the system is able to immediately issue an alarm signal. At the same time, it can measure the position of the shaft very accurately. This is very important for the correct control of the axial or radial position of the shaft during operation. For example, any axial deviation of the shaft can cause serious problems in the turbine system, and the Bently Nevada 3300/61 can monitor these deviations and report the position in real time to prevent any mechanical damage to the machine.

Data Processing: The system is equipped with data processing capabilities. It is able to remove noise and interference from the measurement signal and provide good and reliable data for further analysis. At the same time, it is able to calculate different parameters such as peak-to-peak vibration, RMS vibration, etc. This can serve as a basis for estimating trends, allowing maintenance operators to foresee potential failures and take proactive actions.

Communication Interface: Another important feature is its communication interface. Bently Nevada 3300/61 can easily communicate with other control systems or monitoring units via Modbus or Ethernet data transmission. This enables them to be smoothly integrated into larger industrial automation networks, where data can be consolidated and evaluated at the control center to achieve higher-level control strategies.

Applications

Power Generation: It is used in steam turbines, gas turbines, and generators in the power sector, which are key elements for the uninterrupted and reliable operation of the power generation process. In addition, by continuously monitoring shaft vibration and position, it helps to avoid serious pipeline failures and economically costly downtime. Large power stations may have dozens of Bently Nevada 3300/61 sensors monitoring other turbines and generators, which will be brought together into a monitoring system.

Oil & Gas: Bently Nevada 3300/61 is designed for pumps, compressors and other rotating machinery. The powerful performance of 3300/61 ensures reliable operation of equipment and safety of platforms on offshore oil platforms, which are extremely challenging to maintain.

Manufacturing: Machine tools, motors and industrial fans. For example, in precision manufacturing plants, effective monitoring of installed vibration levels and locations provided by Bently Nevada 3300/61 ensures the quality of manufactured products by keeping tools in correct operating condition.
