18745-03 Bently Nevada 3500 Communication Gateway Module 24 VDC IP20 2×RJ45
The Bently Nevada 18745-03 is a high-performance 3500/42M Proximitor Monitor Module, part of the globally trusted 3500 Machinery Protection System, engineered to deliver continuous, real-time monitoring of shaft vibration, axial position (thrust), and differential expansion in critical rotating machinery. Designed for mission-critical applications in power generation, oil & gas, petrochemicals, and heavy industry, this dual-channel monitor provides API 670-compliant protection with advanced signal processing, configurable alarms, and robust diagnostics—ensuring early fault detection and preventing catastrophic equipment failure.
As an enhanced version of the standard 3500/42 module, the 18745-03 includes Proximitor® Sensor compatibility, meaning it works directly with Bently Nevada’s industry-standard eddy-current proximity probes without requiring external signal conditioners. Each channel independently processes dynamic (AC) and static (DC) components of the probe signal, enabling simultaneous measurement of vibration amplitude (in mils or microns) and shaft position (gap voltage)—essential for comprehensive machine health assessment.
