Deskripsi
Product Description
The Bently Nevada 990‑05‑50‑03‑05 is a compact, integrated vibration transmitter combining a proximity probe, extension cable, and Proximitor® sensor into a single unit. Designed for precise online monitoring of shaft vibration, displacement, and Keyphasor® reference signals, it provides a 4–20 mA output that can be directly interfaced with PLCs, DCS, or other plant control systems.
This transmitter employs non-contact eddy-current technology, offering reliable, high-accuracy measurements in harsh industrial environments. Its rugged construction ensures long-term stability in turbines, compressors, motors, pumps, and other rotating machinery where continuous condition monitoring is essential for predictive maintenance and machinery protection.
