Product Abstract

The 330105-02-12-05-02-01 is a specialized 8mm Reverse Mount Proximity Probe within the Bently Nevada 3300 XL series. Engineered for non-contacting displacement and vibration measurements, it provides industry-leading accuracy for fluid-film bearing machinery. This model features a 3/8-24 UNF threaded case and a ClickLoc coaxial connector, ensuring stable signal transmission in extreme temperatures from -52°C to +177°C.

Oiltech Controls Limited’s Insight

The 330105-02-12-05-02-01 is a critical asset for Reverse Mount configurations, allowing for external installation through machine casings. From an engineering reliability perspective, the 3300 XL 8mm system offers superior moisture resistance. The ClickLoc connector is a major upgrade, preventing the common signal “chatter” found in legacy designs. For pressurized environments in turbines or compressors, the integrated Viton O-ring seal makes the 330105-02-12-05-02-01 an exceptionally robust solution.

Professional FAQ & Procurement Guide

• Question: When should I use the 330105-02-12-05-02-01 instead of a standard probe?

  Answer: This reverse mount model is required when the mounting hole is only accessible from the exterior of the bearing housing or machine casing.

• Question: Does the 0.5m length require a specific extension cable?

  Answer: Yes. For a standard 5m calibrated system, you must pair this 0.5m probe with a 4.5m extension cable. For 9m systems, use an 8.5m cable.

• Question: Is the Viton O-ring suitable for extreme cold?

  Answer: While the probe operates at -52°C, the Viton seal may harden below -34°C. For cryogenic sealing, consult our engineering team for custom options.

• Question: What are the benefits of the ClickLoc connector?

  Answer: The ClickLoc mechanism (Option -02) provides a vibration-proof lock, preventing signal degradation and intermittent “spike” errors in noisy environments.

• Question: Procurement Tip: Is it possible to add armor to this model?

  Answer: This specific configuration is non-armored. If your application involves high mechanical risk or abrasive paths, we suggest upgrading to an armored lead version.
