Bently Nevada 3300/16-12-01-02-03-02-00 Dual Eddy Current Proximity Monitor

Product Description

Overview

The Bently Nevada 3300/16-12-01-02-03-02-00 is a dual-channel eddy current proximity monitor engineered for continuous, real-time vibration and shaft position monitoring in rotating machinery. Designed for critical equipment such as turbines, compressors, and pumps, this monitor ensures reliable protection by measuring radial vibration, shaft eccentricity, and axial displacement (thrust). It represents a direct upgrade from the 3300/15, offering enhanced gap monitoring and independent channel alarms.

Key Features

• Dual independent monitoring channels for simultaneous measurement of radial vibration and shaft position

• Real-time digital display with bar graphs and numeric readouts

• Integrated alert and danger relays for immediate machine protection

• “OK” status circuit with LED and relay to confirm sensor and wiring integrity

• Direct buffered output for diagnostic evaluation of raw vibration signals

• Shaft gap voltage monitoring for linear sensor operation

• User-programmable alarm delays (0.1–60 s) to prevent false trips

Applications

Ideal for monitoring critical rotating machinery, including steam and gas turbines, high-speed compressors, and industrial pumps. The monitor helps prevent mechanical failure by providing early warning of excessive vibration or misalignment.

FAQ

Q: Can this monitor interface with modern 3500 Series systems?
A: While primarily a 3300 Series legacy unit, outputs can be integrated with certain 3500 Series analog inputs with proper scaling.

Q: Does it support hazardous area installations?
A: Yes, with CSA, ATEX, and IECEx approvals for Class 1, Div 2 locations.

Q: What type of sensors are compatible?
A: Standard 8 mm Bently Nevada Proximitor sensors (200 mV/mil sensitivity).

Q: How is this different from the 3300/15?
A: The 3300/16 adds gap voltage monitoring and improved independent channel alarms.
