• Temperature Stability: Maintains accuracy across wide operating temperatures per API 670 requirements.

• Corrosion Protection: Gold-plated connectors resist corrosion and ensure reliable signal transmission.

• Vibration Resistance: ClickLoc connectors feature a locking mechanism that prevents loosening under machinery vibration.

• Fluid Sealing: FluidLoc cable option prevents oil migration through the cable interior.

• No Special Tools: SpringLoc terminals and ClickLoc connectors enable installation and removal without specialized tooling.

• Interchangeable Components: Fully interchangeable probes, cables, and sensors reduce field inventory complexity.

Specific Application

• Continuous radial vibration monitoring inside thick machine casings where the mounting path requires bypassing outer housing elements.
• Axial displacement tracking loops on industrial pumps that utilize custom probe sleeves or mid-depth bracket arrangements.
• Hazardous processing zones needing localized safety approval parameters paired with defensive stainless steel cable shielding.

System Compatibility & Alternatives

• System Compatibility:
  Fully compatible with the Bently Nevada 3300 XL Proximitor Sensor and 3300 XL standard extension cables. It delivers complete physical and electrical interchangeability with legacy, non-XL 3300 series metric 5mm and 8mm transducer elements in compliance with API 670 standard specifications.
• Alternative Model & Differences:
  The corresponding unarmored alternative configuration within the same metric product block is catalog number 330103-07-14-05-01-05.
• The Difference: The 330104-07-14-05-01-05 features a flexible AISI 302 or 304 stainless steel armor sleeve with an outer FEP protective jacket surrounding its triaxial cable, providing maximum defense against cutting, crushing, or abrasion on open machinery. The 330103 alternative is constructed completely "without armor," featuring a smooth FEP triaxial insulation line intended solely for clean routing paths inside rigid internal conduits.

Installation & Troubleshooting FAQ

Q1: What are the torque limits and tool profiles for fastening this 140mm metric case?

A: The maximum rated installation torque for this M10x1 metric threaded forward-mounted probe case is 33.9 N•m (300 in•lbf), and the standard engineering recommended torque is 11.2 N•m (100 in•lbf). If the machine bracket geometry restricts thread mounting down to the first three threads of the hole, the safety ceiling drops to 22.6 N•m (200 in•lbf). The probe casing incorporates 8mm wrench flats and is supplied with a matching locknut containing safety wire holes.

Q2: Why must the unthreaded length be strictly verified against the overall case length during setup?

A: The 70mm unthreaded section enables the field engineer to slide the long probe deep into thick-walled bearing blocks before thread engagement begins, avoiding unnecessary thread binding. Per Bently Nevada engineering rules, the unthreaded length option must always be ordered in 10mm increments and must remain at least 20mm shorter than the total case length parameter to maintain mechanical structural integrity.

Q3: How does the installed '01' connector type option benefit this specific short-cable configuration?

A: The '01' designation signifies that the miniature gold-plated brass coaxial ClickLoc connector is supplied from the factory with a pre-installed fluorosilicone connector protector adapter. This configuration facilitates routing through restrictive spaces, and once the 0.5-meter leading line latches onto the extension cable with an audible "click," the protector slides over the joint to seal out oil mist without requiring manual silicone tape wraps.

Q4: My system reports an unstable voltage output when tracing a small shaft target area. What is the cause?

A: For optimal performance, the minimum recommended shaft diameter for an 8mm probe tip is 76.2 mm (3.0 inches), with an absolute hardware lower limit of 50.8 mm (2.0 inches). Running the sensor over target faces narrower than these thresholds introduces severe target edge errors and shifts the calibrated incremental scale factor away from the standard 7.87 V/mm (200 mV/mil) rating.
