Bently Nevada 3300 XL 25mm Proximity Probe
The Bently Nevada 3300 XL 25mm Proximity Probe is designed to replace older 7200 series and 25mm DE Integral systems, including side and rear exit versions. It delivers the same output as previous models, allowing easy upgrades without monitor changes, but all system components must be replaced with 3300 XL 25mm parts for proper operation.

Description
The Bently Nevada 3300 XL 25mm Proximity Probe is a high-performance eddy current sensor that delivers accurate non-contact measurements of shaft vibration and displacement in critical rotating machinery. Its extended measurement range ensures reliable operation in demanding industrial environments.
The Bently Nevada 3300 XL 25mm Proximity Probe also allows seamless upgrades from older 7200 series and 25mm DE Integral systems, providing the same output signal to avoid changes to existing monitors. For optimal performance, all system components should be replaced with 3300 XL 25mm parts.
