3300 NSv Proximity Probes – Easy-to-Use Eddy Current Sensors

What’s This Product?

The 3300 NSv Proximity Probe is made by Bently Nevada. It’s a sensor that measures position and vibration. It’s better than old 3300 RAM probes at resisting chemicals, so it works well in compressors. It also has better side views than 3000-series 190 probes when placed close to targets.
