By purchasing this item, you agree to the Terms & Conditions, ApterPower is not an authorized distributor for listed manufacturers or tradenames and therefore the manufacturer's warranty does not apply. All our products come with ApterPower's 1-year warranty.
The Bently Nevada 990-04-50-01-00 Vibration Transmitter is primarily aimed at original equipment manufacturers (OEMs) of centrifugal air compressors, small pumps, motors, or fans, who prefer a simple 4-20 mA proportional vibration signal as input to their machinery control systems. This transmitter precisely matches the specified measurement range and mounting requirements, providing stable and reliable signal transmission for vibration monitoring, making it a core component in machinery control systems.
As a two-wire, loop-powered device, the transmitter accepts input from the Bently Nevada 3300 NSv proximity probe and its matching extension cable, supporting system lengths of 5 meters and 7 meters (this model is equipped with a 5.0-meter / 16.4-foot system length). It mounts easily using 35 mm DIN rail clips and does not require additional agency approvals, enabling quick installation and seamless integration into standard industrial control setups.
The transmitter offers excellent signal processing and transmission performance, with a full-scale range of 0-4 mils peak-to-peak (0-100 μm peak-to-peak). It conditions the received vibration signal into peak-to-peak vibration amplitude engineering units and converts it into a 4-20 mA DC standard signal, covering the specified full-scale range and meeting control system input requirements. Additionally, the Prox Out has a 10 kΩ output impedance, calibrated for a 10 MΩ load, ensuring accurate and stable signal transmission and providing reliable data for machinery protection alarms and logic control.
