Product Overview
The Bently Nevada 990-05-70-02-01 Vibration Transmitter is part of the trusted 990 series, designed to provide continuous and reliable vibration monitoring for industrial rotating machinery. This specific model is engineered for use in demanding environments where space is limited, yet high-quality vibration trending is required to prevent mechanical failures. It accepts input from industry-standard vibration sensors (e.g., accelerometers or velocity transducers) and converts the measured vibration signal into a scalable 4–20 mA output signal, suitable for integration into DCS, PLC, or SCADA systems.
Ideal for use in process industries, this vibration transmitter enables real-time condition monitoring of motors, pumps, fans, and other rotating equipment. The model 990-05-70-02-01 offers high sensitivity, robust construction, and intrinsic safety certifications for use in hazardous environments.
