This model is an 8 mm reverse‑mount proximity probe from the renowned 3300 XL Series, designed for critical vibration and position sensing in harsh industrial environments. It supports accurate machinery diagnostics and condition monitoring in rotating systems where space constraints exist.
Brand: Bently Nevada
Series: 3300 XL Reverse‑Mount Proximity Probes
Model: 330105‑02‑12‑05‑02‑00
Product Type: Vibration/Position Sensor Probe
Primary Use: Proximity transducer for industrial vibration monitoring
Compact Reverse Mount Design – Fits tight spaces where traditional side or front mounting isn’t feasible.
8 mm Sensing Tip – Small diameter ideal for limited targets or restricted clearance.
Miniature ClickLoc Coaxial Connector – Secure, durable connector ensures signal integrity.
High-Temp & Rugged Construction – Stainless steel body and PPS tip tolerate wide temperatures and harsh conditions.
Reliable Seal & Materials – Viton® O‑ring ensures pressure sealing; stainless steel case resists corrosion.
Precise Torque Specs – Rated to 22.6 N·m, optimal tightening at 7.5 N·m avoids damage.
This probe is ideal for:
Vibration monitoring of small shafts, bearings, and compressor components.
Use in centrifugal air compressors, refrigeration units, and other machinery with tight clearances.
Integration within advanced condition monitoring systems for early fault detection.

Q1: What’s the purpose of this probe?
A1: It measures vibration or shaft position in tight mounting spaces using precise proximity sensing.
Q2: Is the connector secure and reliable?
A2: Yes—it uses a locking miniature coaxial ClickLoc connector built for industrial durability.
Q3: Can it operate in high heat?
A3: Absolutely—standard range up to +177 °C; extended ratings reach +218 °C at the tip.
Q4: How durable is the probe’s housing?
A4: The stainless steel case with PPS tip and O‑ring sealing ensures high durability and corrosion resistance.
Q5: What makes the 8 mm probe tip advantageous?
A5: It allows access in tight clearances or small target areas where larger sensors won’t fit.
Q6: Is pressure sealing offered?
A6: Yes, the Viton® O‑ring provides differential pressure sealing to protect internal components.
Q7: Can this be used in hazardous areas?
A7: Models with appropriate suffixes include ATEX, CSA, and IECEx approvals for hazardous zones.
Q8: How do I install without over-tightening?
A8: Use the specified 7.5 N·m torque; 22.6 N·m is the maximum to avoid damage.
Q9: What’s the weight and dimensions?
A9: Roughly 0.323 kg; physical size is approximately 20.4 cm × 22.2 cm × 3.7 cm.
Q10: What makes this model stand out?
A10: Its small footprint, rugged design, temperature range, and mounting options make it ideal for compact and critical monitoring needs.
