BENTLY NEVADA 3300/50 Tachometer 82962-01

Bently Nevada 3300/50 is a tachometer designed for condition monitoring within the 3300 series of Bently Nevada products. It is capable of measuring shaft rotational speed and acceleration, as well as providing real-time output for zero-speed detection. This device outputs a proportional voltage or current on its back terminal strip and can signal an Alert status through relay contacts, which can be integrated with an external annunciator panel. Although it functions as a single-channel monitor, it has the capacity to receive input from two transducers and processes the voting logic between them, thereby minimizing the risk of false alarms due to the failure of a single transducer.

Features

- Offering specialized functions as part of a larger system, it's essential to recognize that this device is not suited for standalone operation or integration into speed control or overspeed protection mechanisms. Despite its unique attributes tailored to specific needs, it's imperative to grasp its operational boundaries and its role within the wider industrial framework.

- The tachometers do not possess the necessary attributes for precise speed regulation or reliable overspeed safeguarding. Such tasks necessitate a degree of accuracy, quick response, and redundancy that these devices might not be able to provide.

- When an analog proportional output is available, it is important to recognize that this output is intended only for applications like data logging or chart recording. It may not satisfy the rigorous standards required for dynamic speed control or overspeed protection systems.

- When the component offers speed alert setpoints, it is crucial to understand that these setpoints are designed for notification purposes, not for active control or safeguarding. Their role is to inform operators or maintenance staff about deviations in speed.

- The description highlights the importance of following the specified applications and constraints. Ignoring these cautions and employing the component outside its intended scope could result in improper use, potentially causing damage to property and harm to individuals.

- In instances where machine overspeed protection is required, it is recommended to use Bently Nevada Electronic Overspeed Detection Monitors. These monitors are purposefully designed to deliver the necessary precision, dependability, and quick response for protecting against overspeed scenarios.
