Bently Nevada 1900/17 Proximitor Monitor
Product Description
The 1900/17 is a compact single-channel Proximitor monitor manufactured by Bently Nevada (Baker Hughes), belonging to the 1900 series standalone machinery protection monitors. It works with Bently proximity transducer systems to measure shaft relative vibration, radial displacement, shaft position and gap value of rotating equipment. This unit converts the high-frequency eddy-current probe signal into usable 4–20mA analog output and configurable relay alarm/trip outputs. With local LED status indicators and easy threshold configuration, it delivers continuous online monitoring and protection for critical rotating machinery. As a DIN-rail mount standalone monitor, it is widely used for smaller rotating assets where a full 3500 rack system is unnecessary.
