Product Description
Bently Nevada 1900/65-00-00-01-00-00 (1900/65A) is a standalone general-purpose machinery monitor from Baker Hughes. It is designed for balance-of-plant auxiliary equipment, compact all-in-one vibration and temperature protection instrument without rack chassis. It accepts 4 vibration inputs and 4 temperature inputs, compatible with eddy current probes, accelerometers, velocity sensors, RTDs and thermocouples. Each channel supports independent Alert and Danger alarm setpoints. It provides buffered outputs, 4–20mA analog signals and programmable relays. Configured via 1900 software, it communicates with DCS, PLC and System 1 diagnostic platform. It is widely used for fans, pumps, air compressors and small turbines, and available as spare parts for legacy installations.
