The Bently Nevada 330980-50-00 is a 3300 NSv Proximitor sensor designed for narrow-space vibration monitoring. It provides a linear 200 mV/mil output for critical industrial machinery diagnostics.
The Bently Nevada 330980-50-00 acts as a signal conditioner for the 3300 NSv proximity transducer system. It specifically processes signals from probes with small diameters or narrow installation gaps. This sensor converts eddy current data into a linear voltage output. Consequently, the monitoring system can accurately track radial vibration and axial position. This hardware serves as a critical link between the physical probe and the monitoring rack. It ensures high-fidelity data transmission for machinery protection.
