Overview
The Bently Nevada 1900/65A is a standalone, general-purpose machinery monitor designed for continuous protection of non-critical industrial equipment. Unlike the modular 3500 system, it integrates all monitoring functions, power supplies, outputs, and display capabilities into a single, compact unit.
It supports a wide variety of sensors, including proximity probes, accelerometers, velocity transducers, and temperature sensors, making it ideal for upgrading standard plant machinery to include reliable vibration and thermal protection at a lower cost.

Key Functions and Capabilities
-
Versatile Sensor Support: Each transducer input can monitor radial vibration, acceleration, speed, or position.
-
Integrated Temperature Monitoring: Four channels accommodate thermocouples or RTDs, protecting machinery against thermal faults.
-
Protection Logic: Alert and Danger setpoints on all channels, triggering relays for shutdowns or warnings.
-
Standalone Operation: With the display/keypad module and integrated relays, the monitor functions independently without requiring a DCS or PLC.
-
Condition Monitoring Integration: Optional Modbus Gateway enables connection to SCADA, DCS, or System 1® for centralized monitoring.
Typical Applications
-
Cooling Tower Fans & Pumps: Detects excessive vibration in fans and gear drives.
-
Standby & Utility Pumps: Provides protection for general-purpose pump/compressor motors.
-
Air Handling Units (AHU): Monitors large motors and blowers for continuous operation.
-
Reciprocating Compressors: Monitors rod position and crankcase vibration on smaller compressors.
This monitor delivers high-value protection for secondary or non-critical assets without the complexity or cost of a full rack-based system.
FAQ: Bently Nevada 1900/65A
Q1: How does it differ from the 3500 system?
A1: The 1900/65A is standalone, with fixed channels and integrated components, making it cost-effective for general-purpose machines. The 3500 system is modular, rack-based, and designed for critical machinery with options like Triple Modular Redundancy (TMR).
Q2: Does it support dynamic (raw) vibration data?
A2: Primarily, it provides processed static variables for protection (overall vibration, speed, position, temperature). It can provide buffered raw outputs for external collectors but does not internally store or process dynamic data.
Q3: What does the NEMA 4X/IP66 rating indicate?
A3: The enclosure protects against windblown dust, rain, splashing or hosed water, and corrosion, making it suitable for harsh outdoor or washdown environments.
