330101-01-20-10-02-05 Bently Nevada 3300 XL 8 mm Proximity Probe

Configured for shaft displacement and vibration measurement in the 3300 XL 8 mm Proximity Transducer System, the Bently Nevada 330101-01-20-10-02-05 (330101 8 mm Proximity Probe) provides non-contact eddy-current sensing of radial and axial shaft motion. The probe converts target distance variation into a proportional voltage signal for static position and dynamic vibration measurements.

Hardware Specifications

Eddy-Current Probe Scaling and Gap Validation

The 330101-01-20-10-02-05 uses an eddy-current sensing principle to measure the distance between the probe tip and the conductive machine target. The specified incremental scale factor is 7.87 V/mm, with a tolerance of +/- 6.5%.

The probe provides both static and dynamic displacement information. Static output represents shaft position, while dynamic changes represent shaft vibration or other target movement. During system commissioning, the probe gap and associated voltage output should be checked against the applicable 3300 XL system requirements before machinery operation.

The ClickLoc connector uses a miniature coaxial interface. Its gold-plated, corrosion-resistant construction supports electrical continuity at the probe-to-extension connection. The TipLoc molding secures the probe tip to the probe body, while the CableLoc design secures the cable-to-tip connection.

Frequently Asked Questions

Q: What measurement principle does the 330101-01-20-10-02-05 use?
A: It uses non-contact eddy-current proximity sensing to convert target distance variation into a proportional voltage output.

A: The specified linear range is 2.0 mm (80 mils), approximately covering 0.25 mm to 2.3 mm (10 to 90 mils).

Q: What connector does this configuration use?
A: This configuration uses a miniature coaxial ClickLoc connector with a standard cable.

Field Installation Guidelines

Install the probe with the specified 3/8-24 UNF thread and maintain the required mechanical clearance from the monitored shaft or target. Confirm that the mounting surface and probe axis provide the intended measurement geometry.

Route the probe cable away from high-current power conductors and other sources of electrical interference. Avoid sharp bends, excessive mechanical tension, and unsupported cable sections near the probe connection.

Use the specified ClickLoc connector interface and ensure the connection remains mechanically secure after installation. Check the probe output and target gap during commissioning. Where the monitoring system requires a defined gap voltage, validate the measured output against the applicable Bently Nevada 3300 XL installation requirements.

The supplied data does not specify probe weight, complete assembly dimensions, or power consumption; these values should be obtained from the applicable manufacturer documentation rather than inferred.
