Bently Nevada 88984-01 Dual Vibration Monitor

Product Overview

The Bently Nevada 88984-01 is a high-performance, microprocessor-based monitor designed for the 3300 Series machinery protection system. This module is specifically engineered to accept inputs from two proximity probe/Proximitor sensor systems. It is an essential tool for detecting common machinery faults such as rotor imbalance, misalignment, and bearing wear.

Technical Specifications

• Brand/Manufacturer: Bently Nevada

• Part Number: 88984-01

• System Series: Bently Nevada 3300 Series

• Module Type: XY/Gap Dual Vibration Monitor

• Channels: Two independent channels

Key Features

• XY Configuration Support: Optimized for "XY" probe arrangements (typically 90° apart) to provide a complete picture of the shaft's orbit and dynamic motion.

• Microprocessor-Based Precision: Utilizes advanced digital processing to ensure high accuracy and long-term stability of vibration measurements.

• Integrated LCD & LED Diagnostics: The front-facing LCD provides direct numerical values, while LEDs indicate "OK," "Alert," and "Danger" statuses for immediate visual confirmation.

• Dual-Channel Independence: Both channels operate independently, ensuring that a failure in one monitoring point does not compromise the protection of the second.

• Fluid-Film Bearing Optimization: Specifically tuned to capture the low-frequency and high-frequency characteristics of shafts rotating within oil-film bearings.
