330101-00-30-10-01-00 is a Bently Nevada eddy current application module featuring a 3.0-inch overall case length and a 1.0-meter integrated cable. Fully compatible with 3/8-24 UNF mounting threads, this unit works seamlessly with 3300 XL Proximitor sensors to deliver flexible machinery diagnostics, an integrated pre-installed connector protector, and stable industrial overspeed or vibration monitoring.
Installation & Wiring
- Mechanical Threading: Thread the 3/8-24 UNF-2A probe body directly into the machine casing bracket until reaching the intended measuring gap.
- Locknut Tensioning: Torque the dual locknuts to the recommended 11.2 N•m (100 in•lbf) rating to maintain permanent positioning balance under continuous vibration. Connector Connection: Interlock the gold-plated male ClickLoc coaxial connector with the female extension cable end until an audible click confirms connection.
- Protector Alignment: Slide the pre-installed fluorosilicone connector protector housing over the joined junction path to prevent fluid contaminants from bridging the line.
- Field Component Wiring: Connect the three-conductor shielded triad field cable to the corresponding Proximitor sensor terminal block strips using the tool-free SpringLoc mechanisms.
System Compatibility and Alternatives
- System Compatibility:
Fully compatible with the Bently Nevada 3300 XL 5-meter Proximitor Sensor (e.g., 330180-50-00) and a 4.0-meter 3300 XL standard extension cable (e.g., 330130-040). It provides backward compatibility and interchangeability with legacy non-XL 3300-series 5mm and 8mm transducer systems compliant with API 670 criteria. - Alternative Model:
330101-00-30-10-02-00 (Standard variant without pre-installed connector protector) or 330103-00-08-10-01-00 (Metric M10x1 threaded equivalent). - Difference from Alternative Model:
The 330101-00-30-10-01-00 includes a factory-installed connector protector, shielding the coaxial junction from oil washdowns, whereas the standard -02 option leaves the gold-plated ClickLoc junction exposed to the elements. When compared to the 330103 metric alternative, this probe utilizes imperial 3/8-24 UNF case threads instead of an M10x1 profile, matching distinct infrastructure cutout standards on North American machinery.

Installation & Troubleshooting FAQ
Q1: What is the recommended gap voltage for setting up this 3300 XL 8mm proximity probe?
A: The recommended initial calibration voltage for standard radial vibration tracking is -9 VDC, which positions the probe tip approximately 1.27 mm (50 mils) away from the target surface. For full-scale API 670 testing, a -10.0 VDC gap can be applied to align the sensor exactly at the physical midpoint of its 2.0 mm (80 mils) linear operating range.
Q2: Why does the monitoring system indicate an electrical short or an unexpected "Sensor Limit" fault?
A: This usually points to moisture ingress inside the coaxial connector or cross-talk caused by an overly restricted housing counterbore clearance. Ensure the counterbore diameter surrounding the 8mm tip is at least 24mm wide, and check that the internal golden connector pin is dry and free of conductive turbine oil mist.
Q3: Can the 1.0-meter probe cable be coupled directly to a 9-meter Proximitor sensor?
A: No, 1.0-meter integral probe systems must be combined with a 4.0-meter extension cable to form a complete 5-meter system calibrated to a 5-meter Proximitor sensor. Mixing a 5-meter hardware layout with a 9-meter sensor assembly disrupts internal loop tuning, altering the scale factor and rendering the vibration outputs inaccurate.
