Bently Nevada 84661-20

1.Key Technical Parameters

Measurement Accuracy: When measuring vibration, Bently Nevada 84661-20 has a displacement accuracy of ±0.025mm, a velocity accuracy of ±0.025mm/s, and an acceleration accuracy of ±0.25m/s², which can detect small vibration changes during the operation of the equipment. When measuring temperature, the accuracy does not exceed ±1°C, providing a reliable basis for accurately understanding the thermal status of the equipment.

Sampling Frequency: Bently Nevada 84661-20 is up to 20kHz, which can capture the rapid changes of instantaneous signals during the operation of the equipment. Whether it is a high-frequency vibration spike or a short-term impact signal, it is collected with extremely high precision to ensure the integrity and accuracy of the data, providing a rich source of information for subsequent fault diagnosis.

Number of channels: Through multiple independent measurement channels, key power parameters or various equipment parameters such as shaft vibration, bearing temperature, pressure, etc. can be read simultaneously, providing complete support for all-round data supply on the basis of a comprehensive assessment of the health status of the equipment. 

2. Functional features

Real-time monitoring and alarm: Bently Nevada 84661-20 continuously monitors the operating parameters of the equipment in real time. Once the data exceeds the pre-set safety threshold, it immediately issues an audible and visual alarm, and sends alarm information to the control system or monitoring center through 10 communication interfaces (Ethernet, RS485, etc.), so that timely measures can be taken to prevent the fault from further expanding and ensure production safety.

Data analysis and diagnosis: Bently 84661-20 has built-in advanced data analysis algorithms, which can perform multiple analyses on the collected data in time domain, frequency domain, shaft trajectory, etc. By deeply mining the data, various common fault types such as equipment imbalance, equipment misalignment, equipment bearing failure, etc. can be accurately identified, and detailed diagnostic reports can be output to help factory mechanics easily find the root cause of the fault and propose targeted maintenance plans.

Data storage and transmission function: Bently 84661 - 20 has a large-capacity data storage function, which can save the historical operation data of the equipment for a long time, so that users can query, compare and analyze the historical operation data at any time, trace the complete change process of the equipment operation status, and provide support for optimizing equipment maintenance strategies. At the same time, it supports multiple modes of data transmission, which is convenient for integrating monitoring data into the factory automation management system to achieve remote monitoring and centralized management.

3.Installation and use

Installation environment requirements: Bently Nevada 84661-20 must be installed in a relatively dry, ventilated environment without strong electromagnetic interference sources to ensure stable operation of the equipment. When installing the sensor, you must strictly follow the functional regulations to ensure good contact between the sensor and the equipment to obtain accurate measurement data.

Operation interface: Bently Nevada 84661-20 can change settings with just a few clicks. The intuitive and simple operation interface allows users to set parameters, view data, adjust alarm levels, operate system functions, etc. without any special programming knowledge. Maintenance: Clean the instrument and check the sensor cable for damage. In addition, correct calibration of the device within the manufacturer's specified period is essential to maintain the accuracy of the device during measurement and a long service life, so that it can continue to monitor stably during production.
