Information
- Bently Nevada 330706-005-046-10-02-00 places an 11 mm sensing tip at the target through a metric reverse-mount arrangement. The probe, extension cable and Proximitor work together to measure static position and dynamic shaft vibration.
Electrical lead: 1.0 m with miniature ClickLoc connector
Matched-system output: 3.94 V/mm nominal scale factor
The 1.0 m FEP-insulated, 75-ohm triaxial lead terminates in a miniature ClickLoc connector. Its center-to-outer-conductor resistance is 5.9 ±0.5 ohms. A compatible 4 m or 8 m extension completes a 5 m or 9 m system; the probe, extension and 11 mm Proximitor must be selected as a matching electrical-length combination.
In the matched system, the nominal scale factor is 3.94 V/mm and the linear range is 4 mm, approximately 0.5 to 4.5 mm of target gap. The standard performance setup uses a 2.5 mm gap, AISI 4140 steel target, -24 V DC supply and 10 kΩ load at 0 to +45 °C. Target material and geometry therefore form part of the measurement conditions, rather than being independent of the probe selection.

Original system characteristics, reverse-mount ordering information and metric probe drawing. PDF · 9 pages.330706-005-046-10-02-00 Installation & Verification Guide
Metric reverse mounting, calibrated cable matching, target clearance, gap setting and response verification. PDF · 5 pages.
Application scope: The application descriptions concern a complete calibrated chain. Target material, shaft diameter, clearance and installation temperature all affect suitability.
Metric reverse-mount measurement points
Fit the M10 x 1 reverse case in a matching mechanical arrangement while retaining access to the connector.Shaft-relative vibration channels
Measure dynamic motion with a matched 11 mm transducer chain and an appropriate monitor input.Static shaft position measurement
Use the system DC gap response for position tracking within the qualified linear region.Longer-range proximity systems
Apply the 4 mm system range where target geometry and electrical-length matching support the required measurement.
Confirm M10 x 1 threads and the reverse case arrangement before fitting.
Do not cut, splice or sharply bend the integral calibrated lead.
Check the actual transfer curve around the 2.5 mm nominal gap.
Use the reverse-mount recommendation; do not apply case torque to the connector.
Provide suitable target area and separation to avoid disturbed probe response.
Verify DC position, dynamic response and monitor indication before releasing the machine.

FAQ View All FAQ
-
Which part of 330706-005-046-10-02-00 distinguishes it from an imperial reverse probe?The 330706 reverse-mount case uses an M10 x 1 metric thread and fixed 5 mm unthreaded / 46 mm case geometry. Do not install it into a 3/8-24 UNF mounting hole.
-
Which extension lengths pair with the 1 m lead of 330706-005-046-10-02-00?A matching 4 m extension makes a 5 m system, while a matching 8 m extension makes a 9 m system. Use the corresponding 3300 XL 11 mm Proximitor calibration.
-
Is the 3.94 V/mm output generated directly by 330706-005-046-10-02-00?No. That scale factor belongs to the complete probe, extension cable and Proximitor system. The probe must be connected to the matching conditioner.
-
Why does target material matter when setting 330706-005-046-10-02-00?The specified calibration uses AISI 4140 steel. Different conductivity or permeability can change the transfer curve, so verify the response against the actual target material.
-
What torque should be used on the reverse case of 330706-005-046-10-02-00?The recommended reverse-mount case torque is 7.5 N·m, with a maximum of 22.6 N·m. This is separate from the much lower connector tightening limit.
-
Can the lead of 330706-005-046-10-02-00 be shortened to remove slack?Keep the integral lead intact. Altering the cable changes the calibrated electrical system; route spare length without bending below the 25.4 mm minimum radius.
-
How should a small shaft be assessed for 330706-005-046-10-02-00?The specified system performance uses a minimum shaft diameter of 152 mm and a minimum flat target diameter of 30.5 mm. Smaller geometry requires application assessment and response verification.
-
Does the temperature limit of 330706-005-046-10-02-00 apply to its Proximitor?No. Probe and extension operation extends to +177 °C, while the Proximitor upper limit is +100 °C. Keep each component within its own temperature rating.
