Information
- The extended threaded case of Bently Nevada 330101-00-75-10-02-00 gives the mounting arrangement additional reach while the eddy-current sensing tip remains close to the shaft. The mechanical reach and the calibrated electrical length serve different purposes.
Electrical length: 1.0 m total probe cable
Connection: ClickLoc connector without factory protector
The 1.0 m total probe length must be included in the complete electrical-length calculation. A compatible extension and Proximitor Sensor must form the selected 3300 XL 8 mm system; connector fit alone does not establish calibration.
The complete matched system provides a nominal 7.87 V/mm scale factor and a 2 mm linear measurement range. Radial-vibration setup uses approximately 1.27 mm gap, corresponding to -9 VDC under the specified AISI 4140 steel calibration conditions. Target material and geometry, component temperatures and the signal-conditioning configuration remain part of the measurement specification.
330101-00-75-10-02-00 Official Datasheet Excerpt
The original technical excerpt covers 3300 XL 8 mm probe construction, electrical behavior and system limits relevant to 330101-00-75-10-02-00. PDF · 8 pages.330101-00-75-10-02-00 Installation & Verification Guide
Apter Power installation workflow for the 1.0 m probe, selected case interface, connector protection and commissioning checks. PDF · 5 pages.
Application scope: The applications below concern the complete calibrated measurement chain. Target material, physical clearance and monitor configuration determine suitability for each machine position.
Shaft vibration
Use the 1.0 m probe path to acquire non-contact shaft motion within the calibrated system range.Static shaft position
Condition the probe gap signal with the matched Proximitor Sensor for a monitor configured for position.Machine mounting
The 7.5 inches case and 0 inches unthreaded section define the available reach and support interface for this selection.Measurement-chain renewal
Use the 7.59 ± 0.50 ohm probe resistance as one isolated continuity check before a full gap-response verification.
Limit 3/8-24 UNF thread engagement to 0.563 inch. Case length does not increase this limit.
The 1.0 m total probe length must be included in the complete electrical-length calculation. A compatible extension and Proximitor Sensor must form the selected 3300 XL 8 mm system; connector fit alone does not establish calibration.
The ClickLoc connector is supplied without a factory-installed connector protector. Prevent contact with surrounding conductive surfaces.
Apply the probe temperature limit separately from the lower Proximitor operating-temperature limit.
Verify target material and geometry. AISI 4140 steel is the reference calibration target.
Check actual DC gap and response to controlled displacement before restoring protection.

Technical notes
System relationship: The 1.0 m total probe length must be included in the complete electrical-length calculation. A compatible extension and Proximitor Sensor must form the selected 3300 XL 8 mm system; connector fit alone does not establish calibration.
Connection protection: The standard ClickLoc connection is supplied without a factory-installed connector protector. Keep connector insulation, mechanical support and pressure containment separate.
Calibration boundary: The complete matched system provides a nominal 7.87 V/mm scale factor and a 2 mm linear measurement range. Radial-vibration setup uses approximately 1.27 mm gap, corresponding to -9 VDC under the specified AISI 4140 steel calibration conditions.
FAQ View All FAQ
-
Does the 7.5-inch case on 330101-00-75-10-02-00 change its electrical system length?No. Case reach is a mechanical selection; the total probe length is 1.0 m. Select the Proximitor and any extension cable by the complete electrical length, not the case length.
-
How far may the mounting thread of 330101-00-75-10-02-00 enter the support?Maximum thread engagement for the 3/8-24 case is 0.563 inch. A longer case does not permit deeper engagement; excessive engagement can bind the probe.
-
Which target geometry is suitable for the sensing tip of 330101-00-75-10-02-00?Use a flat target at least 15.2 mm in diameter, or a shaft at least 50.8 mm in diameter; 76.2 mm is the recommended minimum shaft diameter. Nearby conductive surfaces also affect the field.
-
Can 330101-00-75-10-02-00 connect directly to a 1 m Proximitor Sensor?A standard 1 m system uses a 1.0 m probe without an extension cable. Verify the sensor calibration and the complete XL component combination before connection.
-
What resistance should be checked across the disconnected 330101-00-75-10-02-00 probe?The nominal resistance from center to outer conductor is 7.59 ± 0.50 ohm for the 1.0 m probe. This continuity check does not verify the complete system scale factor.
-
Why is 330101-00-75-10-02-00 not a 4–20 mA field transmitter?The probe is an eddy-current sensing element that requires a compatible Proximitor Sensor. The conditioner produces a voltage proportional to the target gap; the probe alone does not provide a powered current-loop output.
-
Does 330101-00-75-10-02-00 include armored cable or a factory connector protector?No. The 330101 construction is unarmored, and connector option 02 uses standard cable with a miniature coaxial ClickLoc connector without the factory-installed protector.
-
How does a different shaft alloy affect calibration of 330101-00-75-10-02-00?The specified system accuracy and interchangeability are based on an AISI 4140 steel target. A different target material requires a calibration assessment rather than automatic use of those accuracy limits.
