Information
- Bently Nevada 330105-02-12-15-02-05 supports rear-access probe installation through a reverse-mount sleeve while retaining the XL 8 mm measurement characteristics.
Lead configuration: 1.5 m; standard cable
Matched-system scale: 7.87 V/mm
The 1.5 m probe length combines with a 3.5 m compatible extension for a 5 m system. The miniature ClickLoc connector couples the passive probe to the electrical chain without adding a separately powered field device.
Sleeve positioning, rear access and the final gap must be checked together. After replacement, verify both continuity and target response so a mechanically correct fit is not mistaken for a correctly calibrated measurement channel.
330105-02-12-15-02-05 Official Technical Excerpt
The original technical excerpt applicable to Bently Nevada 330105-02-12-15-02-05 covers system performance, probe connections and applicable order selections. PDF · 6 pages.330105-02-12-15-02-05 Installation & Verification Guide
Apter Power installation and verification guide covering mounting, cable matching, target clearance, gap and signal checks. PDF · 5 pages.
Application scope: Apply the 3/8-24 UNF installation to its intended target and keep the selected 1.5 m probe length in the electrical-length calculation.
Rear-access installation
Use the reverse-mount sleeve for probe access from the intended side.Sleeve-mounted shaft sensing
Position the tip through a compatible mechanical assembly.Five-metre calibration
Match a 1.5 m probe and 3.5 m extension to the 5 m sensor.Maintenance replacement
Retain sleeve position and verify the restored gap.
Match the 3/8-24 UNF installation and selected case geometry.
Retain the standard cable construction and avoid connector strain.
Match the probe and extension cable to the Proximitor calibration.
Assess target material and clearance before applying nominal sensitivity.
Establish the gap using the complete energized measurement chain.
Check static response, dynamic indication and configured alarms.

Technical notes
Signal and interface: The 2 mm linear range and 7.87 V/mm scale factor belong to the complete matched system; the probe alone does not establish these ratings.
Installation boundary: The reference gap is 1.27 mm (approximately -9 V for radial vibration). Confirm target material, available travel and correct total electrical length before using the nominal calibration.
Technical basis: Bently Nevada 3300 XL 8 mm Proximity Transducer System, 141194 Rev. AN. Ordering selections apply to this complete probe code. Range, scale factor and gap are matched-system values under the specified calibration conditions.
FAQ View All FAQ
-
Is 330105-02-12-15-02-05 a conventional front-mount probe?No. The 330105-02-12 construction is the XL 8 mm reverse-mount probe with 3/8-24 UNF threads.
-
Should the 02-12 fields of 330105-02-12-15-02-05 be decoded as ordinary case options?No. They are part of the fixed reverse-mount designation; use the reverse-mount drawing and sleeve arrangement.
-
How is a 5 m chain assembled around 330105-02-12-15-02-05?Combine its 1.5 m probe length with a compatible 3.5 m extension and a 5 m Proximitor.
-
What nominal resistance belongs to 330105-02-12-15-02-05?For a 1.5 m probe, nominal center-to-outer-conductor resistance is 7.73 ohm ±0.50 ohm.
-
Does 330105-02-12-15-02-05 require a separate positive DC supply at the tip?No. The passive probe connects through the matched cable to its Proximitor, which provides the system electronics.
-
Why must the sleeve be checked when fitting 330105-02-12-15-02-05?Reverse mounting depends on the sleeve and rear-access arrangement; a matching thread alone does not prove correct probe position or access.
-
Which connector is selected on 330105-02-12-15-02-05?The 02 connection uses a miniature ClickLoc coaxial connector with the standard probe cable.
-
What system calibration applies after installing 330105-02-12-15-02-05?Use the matched XL 8 mm system scale of 7.87 V/mm and its 2 mm linear range under the specified target and temperature conditions.
