Bently Nevada 330704-000-050-10-02-05 Armored M14×1.5 Proximity Probe
An armored M14×1.5 probe with a one-metre lead and multiple-approval option.
Overview
330704-000-050-10-02-05 is an armored metric probe for the 3300 XL 11 mm transducer system. The order code defines zero unthreaded length, a 50 mm case, one-metre lead, miniature ClickLoc connector and multiple approvals.
Its longer 11 mm linear range supports machinery measurements where a standard 8 mm system may not provide enough travel.

Features
- Armored cable adds mechanical protection for exposed routing.
- M14×1.5 case includes the standard locknut with safety-wire holes.
- One-metre lead supports five- or nine-metre calibrated loop construction with the correct extension cable.
- Multiple-approval option supports documented classified-area installations when the whole loop complies.
Applications
- Thrust-position or differential-expansion measurement on fluid-film-bearing machines.
- Protected probe routing in turbine or compressor monitoring systems.
- Maintenance replacement where the exact M14 case and approval option are recorded.
Lifecycle
- Measure the installed insertion depth and record gap voltage.
- Inspect the M14×1.5 thread and confirm thread engagement does not exceed 21 mm.
- Route armor above the minimum bend radius and protect the connector.
- Revalidate the complete monitoring channel after installation.
FAQ
What does the armored construction of 330704-000-050-10-02-05 change?
It adds flexible stainless-steel mechanical protection but still requires correct bend radius and strain relief.
Can 330704-000-050-10-02-05 replace an unarmored 330703 probe?
Only after confirming routing space, connector clearance, mounting geometry and approval documentation.
Which extension cable length matches 330704-000-050-10-02-05?
Combine its one-metre lead with the extension cable required to reach the connected five- or nine-metre 11 mm Proximitor system.
What is the maximum M14 thread engagement for 330704-000-050-10-02-05?
Bently Nevada lists 21 mm as the maximum engagement for M14×1.5 probe cases.
Does 330704-000-050-10-02-05 alone make the loop approved?
No. The probe, extension cable, Proximitor, barriers and field wiring must follow the applicable installation drawing.
What commissioning data should be recorded for 330704-000-050-10-02-05?
Record gap voltage, scale factor, linear response, waveform, channel scaling and alarm or trip verification.
