Description

Continuous machinery protection and localized monitoring are achieved efficiently using the Bently Nevada 1900/65A General Purpose Equipment Monitor. Designed primarily for essential or general-purpose machines, this self-contained system processes dynamic vibration and static temperature inputs to generate real-time alarms, protecting critical processes from catastrophic mechanical failures. The 1900/65A-00-00-01-00-00 configuration operates on low-voltage DC power and is optimized for space-constrained installations where local display or communication bus protocols are not required on-board.

This compact monitor accepts inputs from a variety of transducers, including proximity probes, accelerometers, and velocity sensors, alongside static temperature sensors like RTDs or thermocouples. It serves as an ideal standalone solution for critical ancillary equipment such as small pumps, fans, blowers, and electric motors where larger rack-based systems are not economically practical.

Features

• Four dynamic channels configurable for vibration, position, or speed monitoring.
• Two static channels configurable for temperature or process variable monitoring.
• Four configurable alarm relays for automated machinery shutdown and alert logic.
• Dedicated buffered transducer outputs providing raw sensor signals for portable diagnostic analyzers.
• Rugged, industrial-grade design suitable for harsh operational environments.
• Direct 18 to 36 Vdc power input integration for standard industrial control loops.

Applications

• Cooling tower fans and industrial ventilation blowers
• Water and wastewater centrifugal pumps
• Electric motors and small generators
• Lube oil skid systems and auxiliary equipment
• Centrifuges and industrial air compressors

Installation Guidelines

For reliable system performance and noise immunity, ensure the 1900/65A is mounted on a flat, low-vibration surface or within a protective enclosure if installed in outdoor or washdown environments. All signal wires must use shielded, twisted-pair cabling with shields terminated at the monitor's ground block only. Maintain separate routing for power lines and high-frequency transducer lines to prevent electromagnetic cross-talk. Confirm input voltage parameters fall strictly within the 18 to 36 Vdc threshold before energizing the device.
