Bently Nevada 3300/16 | 3300/16-12-01-02-01-02-00 | Dual Eddy Current Monitor

Product Description

Overview
The Bently Nevada 3300/16 (Part Number: 3300/16-12-01-02-01-02-00) is a high-performance dual-channel eddy current proximity monitor designed to deliver continuous, real-time measurements of radial vibration and axial position (thrust) for critical rotating machinery, including turbines, compressors, and pumps. This model is a core component of the 3300 Monitoring System and supersedes the 3300/15 by adding radial position gap alarm functionality.

Key Features

• Dual independent channels for separate signal monitoring

• Real-time LCD display with digital readouts and bar graph visualization

• Integrated alert and danger relays for triggering machine trips or alarms

• OK status LED and relay ensure sensor and cabling integrity

• Accepts standard 3-wire Proximitor sensor inputs
