製品紹介
The Bently Nevada 990-05-70-01-IN 990 Vibration Transmitter is designed for continuous monitoring / vibration levels in rotating machinery. It converts the dynamic vibration signal from compatible probes or sensors into a standard 4–20 mA output that can be easily integrated into distributed control systems (DCS), programmable logic controllers (PLC), or condition monitoring systems. This model is particularly suited for machinery protection and predictive maintenance, ensuring operators have reliable data for timely decision-making.
