Description

The Bently Nevada 1900/65 General Purpose Equipment Monitor is a compact, standalone monitoring device engineered for small and mid-sized machinery. It provides continuous, online monitoring of critical parameters including vibration, position, temperature, pressure, and overspeed. This unit serves as a cost-effective machinery protection solution, delivering essential monitoring capabilities without the requirement of a full-scale rack-based system.

Features

• Four independent channels for vibration and position monitoring.
• Multi-sensor compatibility, supporting Proximitor sensors, Velomitor transducers, accelerometers, RTDs, and thermocouples.
• Programmable alarm setpoints with dedicated relay outputs for Alert and Danger conditions.
• Buffered transducer outputs provided for advanced diagnostic analysis.
• 4-20 mA proportional outputs for seamless integration with PLC or DCS control systems.
• Compact, space-saving design suitable for DIN-rail or panel mounting.

Applications

The 1900/65 is specifically designed for the protection of general-purpose machinery, including:

• Centrifugal pumps and fans
• Electric motors
• Compressors
• Small turbines and blowers

Technical Specifications

Installation Guidelines

• Ensure the device is installed in a location that meets the specified operating temperature range.
• Use shielded cabling for all transducer inputs to minimize electromagnetic interference (EMI).
• Verify that all power is disconnected before installing or removing the module from the DIN-rail or panel.
• Ensure proper grounding of the chassis to the system common to maintain signal integrity.
• Follow standard ESD handling procedures when touching internal components or connectors.

FAQ

Is the 1900/65 compatible with existing Bently Nevada 3500 series sensors?

Yes, the 1900/65 is designed to interface with standard Bently Nevada proximity probes, Velomitor sensors, and accelerometers, making it a versatile choice for sites already utilizing Bently Nevada instrumentation.

Can this monitor be used for safety-critical applications?

The 1900/65 is designed for machinery protection and meets API 670 requirements; however, it is intended for general-purpose equipment and should be evaluated against your specific site safety requirements for critical assets.
