Bently Nevada 3300 XL 330100-50-00 Proximity Probe Sensor

Product Description

Overview

The Bently Nevada 330100-50-00 is a precision 8 mm proximity probe from the 3300 XL series, engineered for non-contact measurement of shaft vibration and position. Designed for high-reliability industrial applications, it provides a voltage output proportional to the distance between the probe tip and a conductive target, capturing both static position and dynamic vibration.

This specific configuration, -50-00, features a total cable length of 5.0 meters and standard agency approvals for general-purpose industrial environments. Its rugged construction and advanced eddy-current sensing make it suitable for demanding machinery such as turbines, compressors, and high-speed motors.

System Components

• 3300 XL 8 mm Probe: Measures shaft distance and converts it into a voltage signal for static and dynamic monitoring.

• 3300 XL Proximitor Sensor: Processes the probe output to provide reliable vibration and position data, with enhanced immunity to electrical interference.

• 3300 XL Extension Cable (Optional): Connects the probe to the Proximitor if a different total system length is required.

FAQ

Q: Can the 330100-50-00 probe be used with an extension cable?
A: Yes, but the Proximitor must be configured to account for the total system length to maintain accuracy.

Q: What environments are suitable for this sensor?
A: It operates reliably in extreme temperatures and high-EMI industrial environments.

Q: Is system recalibration required when replacing the probe?
A: No, the 3300 XL series allows direct replacement without recalibration if the total cable length remains 5.0 meters.
