Product Description

Overview

The Bently Nevada 3300/16-12-01-02-00-00-00 is a dual-channel eddy current proximity monitor designed for continuous real-time monitoring of rotating machinery. It provides precise measurement of radial vibration and average shaft position, helping detect potential mechanical faults in critical equipment such as turbines, compressors, and large motors. As a member of the legacy 3300 Series, it offers robust, reliable performance in demanding industrial environments.

Key Features

• Dual independent monitoring channels for radial vibration and shaft position
• Front-panel LCD showing numeric values and bar graphs for both channels
• “OK” status circuit with LED indicator for sensor and wiring health
• Buffered front-panel outputs for raw vibration signal diagnostics
• Compact, modular design suitable for rack installation
• Designed to comply with API 670 standards for machinery protection

FAQ

Q: Can this unit be integrated with modern Bently Nevada systems?
A: Outputs can interface with certain 3500 Series analog inputs using proper scaling.

Q: Does it include alarm relays?
A: This specific configuration does not include relays; monitoring relies on external system logic.

Q: What is the difference between 3300/16 and 3300/15?
A: The 3300/16 adds shaft gap monitoring and enhanced dual-channel monitoring compared to the 3300/15.
