Bently Nevada is a global leader in industrial asset condition monitoring and protection, specializing in vibration, pressure, and speed measurement solutions for critical machinery. Founded in 1956 by Don E. Bently, the company pioneered eddy-current proximity probes, revolutionizing rotor dynamics monitoring. Acquired by GE in 2002, Bently Nevada operates in over 50 countries, serving industries such as oil & gas, power generation, and mining. Its product portfolio includes sensors, monitoring systems like the 3500 Series, diagnostic instruments, and predictive maintenance software such as System 1. With over 25,000 customers worldwide, the company combines more than 60 years of expertise with cloud-connected solutions to enhance asset reliability and operational safety.
The Bently Nevada 1900/65A is a versatile general-purpose equipment monitor designed for continuous vibration and temperature monitoring of industrial machinery. It serves as a cost-effective solution for non-critical or auxiliary equipment, providing reliable protection without the complexity of higher-end systems. The monitor supports multiple sensor inputs, including accelerometers, velocity sensors, proximity probes, and various thermocouple/RTD types for temperature measurement. It features configurable relay outputs, analog recorder outputs, and communication options such as Modbus over Ethernet or RS-232/485 for integration with control systems.
This monitor is commonly used in power generation, oil and gas, and manufacturing industries to protect assets like turbines, pumps, compressors, and fans. It includes adjustable filtering and trip-multiplier functions to avoid false alarms during machine startup or transient conditions. The 1900/65A can operate as a standalone device or connect to condition monitoring software such as System 1 for advanced diagnostics. Its rugged design supports DIN rail or panel mounting and meets industry certifications for hazardous environments. Optional display modules allow for local configuration and real-time monitoring.
