1. Technical Parameter

l Operating Temperature: 32°F to 149°F.

l Storage Temperature: -40°F to 185°F .

l Humidity: 0 to 95%, noncondensing.

l I/O Channels: Sixteen-channel relay, providing sixteen independently-programmable relay outputs.

l Input Voltage: 95-125 VAC.

2. Function Features

l Real-Time Monitoring and Display: Bently Nevada 3300/10 continuously monitors vibration levels in real-time with an easy-to-read display of parameter values such as displacement, velocity, and acceleration. This enables the operator to understand the immediate vibration condition of the machinery.

l Alarm and Trip Settings: Bently Nevada 3300/10 allows custom user settings for alarm and trip levels, based on the specifics of the machinery. If the vibration levels exceed the preset cutoff points, this will activate audible and visual alarms, and if desired, can trip the machinery to avoid severe damage.

l Data Logging and Trend Analysis: Bently Nevada 3300/10 stores vibration data over time and provides the means to look back at historic data for reporting purposes. With built-in trend analysis tools, users can detect changes in long-term characteristics of vibration, which can allow users to anticipate possible hazardous conditions in the machinery and schedule preventive maintenance activities.  

l Sensor Integration: Seamless integration with Bently Nevada's broad sensor offering, giving surety of compatibility and dependability in modern applications. Bently Nevada 3300/10 can automatically recognize and configure each connected sensor, allowing for simple installation and set-up.

3. Applications

l Steel Industry: In the steel mill, stability of operation of the rolling mill is critical to the product quality and production efficiency. Bently Nevada 3300/10 measures the vibration monitoring of the rolling mill, accurately collecting the vibration parameters each key part of the rolling mill. During a production cycle, the systems detected a sudden change in the vibration amplitude of the rolling mill. After investigation, it was found that there was unequal wear on the rolls. Timely replacement of the rolls avoided a steel surface problem due to rolling mill failure.

l Machinery Manufacturing Industry: Bently Nevada 3300/10 monitors spindle vibration on CNC machine tools in the CNC machining workshop of a machinery manufacturing entity. Real-time data analysis on vibration allows the technician to comprehend the working status of such machine tools. In vibration abnormalities, the root cause can be a tool wear, workpiece clamping, or machine tool setup, and the technician can take the necessary corrective steps, enhancing not only the machining accuracy but the production efficiency.

Power Generation Industry: Bently Nevada 3300/10 is used for shaft vibration, shaft displacement, key phasor, and rotational speed monitoring of steam turbines in large thermal power plants. It is highly capable of real-time condition monitoring, enabling the identification of tiny changes in vibration signals originating from the operation of a steam turbine, and is able to detect a fault already in its infancy due to bearing wear, thus preventing a unit shutdown fault escalation which would entail considerable amounts in maintenance costs and downtime to the power plant.
