Description：

The Bently Nevada 330101-00-39-10-02-05 is a precision 3300 XL 8 mm Proximity Probe engineered for continuous monitoring of rotating equipment in demanding industrial environments. 

Operating on the principle of eddy current sensing, the probe detects the clearance between its sensing tip and a conductive shaft or target. The measured gap is converted into a proportional electrical output, allowing the monitoring system to capture both steady-state shaft position and dynamic vibration with high repeatability. This measurement method is well suited to equipment where accurate shaft motion data is essential for safe and efficient operation.

When integrated with a compatible 3300 XL extension cable and Proximitor Sensor, the probe forms a complete transducer solution that delivers stable performance across varying operating temperatures and process conditions. The standard 3300 XL 5-meter system is manufactured to satisfy the performance requirements of API 670, making it a preferred choice for critical machinery protection applications in process industries.

Frequently asked questions

Q : What thread type does the 330101 prefix specify?

A: It indicates a standard fractional thread style, specifically a 3/8-24 UNF thread without armor protection.

Q : Can I use this probe in explosion-proof or hazardous environments?

A: Yes. The -05 option provides multiple hazardous area approvals, meeting international certification standards like ATEX, IECEx, and CSA for explosive atmospheres.

Q : What is the default linear range of an 8mm probe system?

A: The standard linear range is 2.0 mm (80 mils), starting from approximately 0.25 mm (10 mils) to 2.25 mm (90 mils) away from the target.

Q : What target material is this 3300 XL probe factory-calibrated for?

A: It is calibrated by default for AISI 4140 steel. Using other metals requires system recalibration or scale factor adjustments.
