Information
- Bently Nevada 330701-00-10-10-02-00 places the sensing tip at the shaft or thrust target while the signal conditioner remains accessible outside the measurement point. The installed probe, extension cable and Proximitor form one calibrated electrical system.
Lead and connector: 1.0 m, miniature ClickLoc, standard cable
Matched-system performance: 3.94 V/mm scale factor and 4.0 mm linear range
The 1.0 m integral lead uses FEP-insulated, 75-ohm triaxial cable and a miniature ClickLoc connector. Adding a compatible 4.0 m or 8.0 m extension produces the 5.0 m or 9.0 m electrical length required by the matching 3300 XL 11 mm Proximitor. The cable bend radius must remain at least 25.4 mm.
The complete 11 mm system measures static position and dynamic displacement with a nominal 3.94 V/mm scale factor and 4.0 mm linear range, approximately 0.5 to 4.5 mm from the target. These are matched-system values; the standard reference setup uses an AISI 4140 steel target, a 2.5 mm gap, -24 V DC supply and 10 kΩ load at 0 to +45 °C.

Measurement applications: The applications below describe the complete calibrated system. Target material, geometry, gap and channel configuration determine suitability for the installed machine.
Axial thrust position
Use the matched system linear range to monitor a thrust target, with sufficient target area and stable probe support.Radial shaft displacement
Observe non-contact shaft motion on fluid-film-bearing machinery using the correct 11 mm conditioner and monitor scaling.Compressor rod position
Apply the complete transducer system to rod position or rod-drop measurements after checking target geometry and mounting clearance.Ramp differential expansion
Use the long-range system in an engineered steam-turbine ramp arrangement; the mechanical ramp geometry is part of the measurement design.
Check the zero unthreaded section, case reach and 0.750 in maximum thread engagement before seating the probe.
Combine the 1.0 m lead with the proper 4.0 m or 8.0 m extension and corresponding Proximitor.
Use 15.2 N·m recommended case torque; the coaxial connector is finger-tight with a 0.565 N·m maximum.
Keep cable bends at or above 25.4 mm radius and prevent unsupported pull or abrasion.
Use the intended target material and review cross-talk where target area or probe spacing is limited.
Set the gap and demonstrate a proportional output through the monitor before restoring the monitoring function.

Technical notes
Electrical-length relationship: The 1.0 m probe requires a 4.0 m extension for a 5.0 m system or an 8.0 m extension for a 9.0 m system. Use matching 3300 XL 11 mm components throughout.
Calibration conditions: System specifications use an AISI 4140 target, -24 V DC supply, 10 kohm load and nominal 2.5 mm gap under the specified reference conditions. They are not standalone probe-output ratings.
Mechanical limits: Observe the 1/2-20 engagement limit and separate probe-case torque from connector torque. The unarmored lead requires appropriate routing protection.

FAQ View All FAQ
-
How do the 00-10 case options shape the installation of 330701-00-10-10-02-00?They select a zero-length unthreaded section and a 1.0 in overall case. Use the 1/2-20 UNF mounting arrangement and verify available adjustment travel against the actual target position.
-
Which extension completes a 5 m channel using 330701-00-10-10-02-00?Its 1.0 m probe length requires a 4.0 m 3300 XL 11 mm extension with a 5.0 m Proximitor. The sum of probe and extension lengths must match the conditioner calibration.
-
What resistance check is appropriate for the disconnected 330701-00-10-10-02-00 probe?The 1.0 m probe DC resistance is 5.9 ±0.5 ohm from center conductor to outer conductor. Compare the isolated probe with that value; measuring a complete connected circuit is not the same test.
-
Is connector protection included in the 02 option of 330701-00-10-10-02-00?The 02 option specifies a miniature ClickLoc connector with standard cable, without the ordered connector protector. Provide suitable connector protection for the installation; silicone tape is not recommended where the joint is exposed to turbine oil.
-
How tightly should the ClickLoc joint of 330701-00-10-10-02-00 be secured?Finger-tight connection is recommended, with 0.565 N·m maximum connector torque. This limit applies to the coaxial connection and is much lower than the 15.2 N·m recommended probe-case torque.
-
Can 330701-00-10-10-02-00 replace only the probe in a 7200-series measurement chain?A 7200-to-3300 XL 11 mm conversion requires replacement of all transducer components with the matching XL 11 mm components and review of the monitor configuration. Do not assume that changing this probe alone creates a calibrated system.
-
Why can two 330701-00-10-10-02-00 probes influence each other near a small target?Their electromagnetic fields can interact when target geometry or probe separation is insufficient. The recommended minimum flat-target diameter is 30.5 mm and shaft diameter is 152 mm. Smaller arrangements require a specific cross-talk assessment rather than an assumed accuracy.
-
What thread-engagement limit should be checked before seating 330701-00-10-10-02-00?The maximum listed engagement for a matching 1/2-20 internal thread is 0.750 in. Excessive engagement can cause binding. Confirm the mounting bore and available travel before applying the recommended case torque.
