Bently Nevada 330901-10-60-70-02-05 3300 NSv Proximity Probe
An unarmored 3300 NSv probe with a long case, 7 m cable and ClickLoc termination for constrained installations.
Product Profile
Bently Nevada 330901-10-60-70-02-05 is a 3300 NSv proximity probe with 1/4-28 UNF thread and no armor. Its ordering code defines 1.0 in unthreaded length, 6.0 in overall case length, 7.0 m total probe length, a ClickLoc connector with standard cable and Multiple Approvals.
The NSv system is intended for machines where counterbore, side-view or rear-view restrictions limit standard 5 mm or 8 mm systems. It also supports small-target radial vibration, axial position, tachometer, zero-speed and phase-reference applications when the full NSv chain is correctly selected.
Technical Data
System Role
Narrow-side-view geometry supports locations where standard proximity probes have insufficient clearance.
The NSv system provides a 1.5 mm linear range and the common 200 mV/mil scale-factor class.
The 7 m probe is selected as a complete ordering execution rather than created by field extension of a shorter probe.
Small-target and cross-talk constraints must be reviewed when probes are closely spaced.
Compatibility & Service
- Record the complete probe, extension cable and NSv Proximitor sensor codes.
- Maintain the documented minimum probe-tip separation where adjacent sensors could interact.
- Preserve the long probe case from bending and support the 7 m cable without tensile load.
- After installation, confirm gap, scale response, channel polarity and frequency behavior.
Applications
- Centrifugal air, refrigeration and process-gas compressor monitoring.
- Radial vibration and position measurement on small shafts.
- Axial position measurement on restricted flat targets.
- Tachometer, zero-speed and phase-reference sensing with the compatible NSv chain.
FAQ
Q01Why is 330901-10-60-70-02-05 not interchangeable with a standard 3300 XL 8 mm probe?+
NSv has different small-target, side-view and linear-range behavior and must be used with the compatible NSv extension cable and Proximitor sensor.
Q02What dimensional evidence is needed for this long-case 330901 probe?+
Provide insertion depth, bracket thickness, counterbore diameter, target clearance and the available path for the 6.0 in case and 7 m cable.
Q03Can a shorter cable be substituted for the 70 option?+
Only by redesigning and documenting the complete NSv system-length combination; the submitted probe is specifically configured as a 7 m execution.
Q04What can cause cross-talk in a 330901-10-60-70-02-05 installation?+
Closely spaced probe tips on small shafts can allow their electromagnetic fields to interact, so target size and tip separation must be checked.
Q05What should be included in a replacement acceptance record?+
Keep the exact probe and Proximitor identities, final gap, target geometry, cable routing, static output, dynamic response and channel alarm test.
