Product Description

Overview

The Bently Nevada 330100-90-00 is an industrial-grade 8 mm proximity sensor from the 3300 XL series, engineered for precise shaft position and vibration monitoring. Designed for high-reliability operation in extreme industrial environments, it measures both static distances (shaft position) and dynamic displacements (vibration) without physical contact.

This eddy-current sensor converts variations in a magnetic field into a linear voltage signal, delivering highly accurate readings for critical machinery applications. The "-90-00" configuration indicates a total cable length of 9 meters and a standard, unarmored connector.

FAQ

Q: Can the 330100-90-00 probe be used with a shorter Proximitor?
A: No, matching cable length is critical. Using a 5-meter Proximitor will result in calibration errors.

Q: Is the probe compatible with other 3300 XL probes?
A: Yes, probes, extension cables, and Proximitors are interchangeable if total system length is maintained.

Q: How should the probe tip and cable be maintained?
A: Keep the tip clean from debris and secure the cable to prevent mechanical noise from vibration.
