Advanced Proximity Measurement for 3500 Machinery Protection Systems
The Bently Nevada 3500/40M-01-05 functions as an advanced proximitor monitor module within the 3500 series machinery protection system. This module accepts up to 4 proximity probe inputs for measuring radial vibration, axial position, and eccentricity. Its sturdy housing measures 241 mm in height, 38 mm in width, and 241 mm in depth, fitting standard 3500 rack configurations seamlessly. The total weight reaches approximately 1.3 kg, providing robust durability for demanding continuous monitoring applications.
Each channel delivers 16-bit resolution for precise measurement of shaft dynamics and position. The following table details the complete technical specifications for this proximitor monitor:

Measurement Modes and Probe Compatibility
The 3500/40M-01-05 supports 5 mm, 8 mm, and 14 mm proximity probes for versatile installation. Each channel operates independently, measuring radial vibration, axial position, or eccentricity. This multi-mode capability adapts to various monitoring requirements. Engineers can therefore configure the module for turbines, compressors, and other rotating equipment.
Signal Processing and Measurement Accuracy
Each channel provides 16-bit resolution with ±0.5% full-scale accuracy for reliable data. The frequency response from 0.5 Hz to 10 kHz covers slow roll and high-frequency vibration components. The module includes integrated signal conditioning for probe linearization. Users benefit from accurate measurement data for condition monitoring.
System Integration and Protection Features
The module interfaces with the 3500 rack backplane for seamless system integration. It provides programmable alarms for vibration and position thresholds. The monitor also supports relay outputs for external annunciation. Maintenance teams can therefore implement comprehensive protection strategies for critical assets.
