Description
Are you experiencing high-frequency cable damage on your industrial steam turbine housing? In tight-clearance turbine or compressor decks, routing unprotected coaxial cable often leads to physical cuts, sheath crushing, and lost data. The Bently Nevada 330102-60-96-10-02-CN 3300 XL 8mm Proximity Probe directly addresses this risk by featuring built-in, rugged stainless steel armor. This armored shielding shields the delicate internal 75 \Omega coaxial line from physical impact and abrasive wear inside heavy B2B environments.
For facilities coordinating maintenance turnarounds, we supply the 330102-60-96-10-02-CN in New Original (Factory Sealed) condition, backed by our 1-year replacement warranty. Standard lead times for this in-stock part are 1 to 2 business days.

Field Performance & Application Notes
Having integrated dozens of these sensors across heavy industrial turbine decks, this specific probe configuration—featuring a long 6.0-inch unthreaded section—is designed for deep-well mounting sleeves where a long smooth section is required to pass through outer bracket flanges before the threads engage.
However, do not attempt to force the armored section of the cable through tight bends during installation. The flexible stainless steel armor has a strict minimum bend radius of 25.4 mm (1.0 inch). Kinking the armor can crush the underlying coaxial line, resulting in erratic voltage drops that mimic true shaft vibration on your monitoring rack.
Strategic Pros & Cons
- Pro: Built-in stainless steel armor provides robust mechanical protection without requiring extra external conduit runs.
- Pro: ClickLoc coaxial connector features gold-plated contacts that resist corrosion from hot oil mist.
- Con: Deep 9.6-inch case length is highly application-specific and cannot easily be used as a universal spare for short-well applications.
- Con: The -CN regional approval code may restrict immediate global cross-site sharing if other plants operate strictly under standard CSA/FM guidelines.
Quick Conclusions
- Ideal for deep-well sensor ports requiring robust mechanical shielding.
- Eliminates the need to run separate flexible conduit inside the machine housing.
- The -CN option provides verified compliance with Chinese NEPSI hazardous area standards.
FAQ
- Can I use this 1.0-meter probe with a standard 9-meter extension cable? No. To achieve a calibrated total system length, this 1.0-meter probe must be paired with an 8.0-meter extension cable (or a 4.0-meter extension cable if utilizing a 5-meter Proximitor sensor).
- Does the armor run the entire length of the cable? The stainless steel armor extends from the back of the probe case to within approximately 100 mm (4.0 inches) of the ClickLoc connector, leaving a short flexible section for final connection.
- Can the probe tip withstand high-pressure steam leaks? The PPS probe tip is hermetically sealed against the stainless steel case, but it is not intended to serve as a high-pressure pressure barrier. Verify your system’s pressure limits with the OEM datasheet prior to installation.
