Bently Nevada 1900/65A General Purpose Equipment Monitor

Overview

The Bently Nevada 1900/65A General Purpose Equipment Monitor is a versatile machine condition monitoring system engineered to continuously measure, evaluate, and protect essential industrial equipment, from fans and pumps to compressors and motors. It combines powerful multichannel sensor inputs, configurable logic, and flexible outputs — all in a standalone monitor designed for long-term reliability in harsh environments. 

Key Functional Features

• Multi-Channel Transducer Input: The 1900/65A supports up to four transducers, configurable for velocity, acceleration, proximity, position, or speed sensors, enabling broad machinery protection coverage. 

• Temperature Inputs: Four temperature channels accept thermocouples (Types E, J, K, T) and RTDs, providing both vibration and thermal condition insights. 

• Robust Outputs: Six relay outputs and four 4–20 mA recorder outputs allow direct integration with PLCs, DCS, SCADA, and plant safety systems. 

• Configurable Logic: Users define alarm thresholds and relay logic through dedicated configuration software, supporting complex condition and alarm models tailored to each machine. 

• Modbus Communications: Optional Modbus TCP/RTU gateway provides static variables, event lists, and status registers to higher-level automation systems. 

• Flexible Mounting: Available in DIN rail, bulkhead, or NEMA 4X/IP66 weatherproof housing for protection in both indoor and rugged outdoor industrial settings. 

• Optional Local Display: An attachable display/keypad module enables on-site viewing of key variables without an external system. 

Designed for Industrial Monitoring & Protection

The 1900/65A is engineered to continuously monitor essential, balance-of-plant, or stand-alone equipment where traditional rack-based systems (like Bently Nevada 3500) may not be economically justified. Its flexibility makes it particularly suitable for:

• Cooling tower fans, blowers, and small motors

• Pumps, air compressors, and centrifuges

• Packaging, process, and utility plant equipment

• Hydro turbines and smaller reciprocating compressors

• OEM rotating machinery with monitoring needs 

By integrating vibration, position, and temperature data, the 1900/65A helps maintenance teams detect early signs of imbalance, bearing problems, misalignment, and thermal issues — supporting predictive maintenance and minimizing unplanned downtime. 

Industrial Benefits

• Continuous Online Protection: Real-time monitoring supports fault detection and automated responses. 

• Improved Asset Reliability: Early anomaly detection helps reduce catastrophic failures and component damage. 

• Flexible Integration: Output options and communications support both local control logic and enterprise-wide systems. 

• Scalable Deployment: Suitable for both individual machine monitoring or distributed monitoring networks with Modbus/SCADA connectivity.
