Core Technical Specifications

• Measurement Range : Optimized for AISI 4140 steel target, with standard factory gap at 1.27 mm (50 mils).
• Sensitivity & Linearity : Less than 2 mV change per volt of supply variation. System uses -24 Vdc supply with 10 kΩ load.
• Power Requirements : Operates on -17.5 Vdc to -26 Vdc at 12 mA maximum. Operation above -23.5 Vdc may reduce linear range.
• Probe DC Resistance : 7.59 Ω ± 0.50 (for 1.0 m length) between center and outer conductor.
• Temperature Range : -35°C to +177°C (-31°F to +351°F). Avoid below -34°C to maintain pressure seal integrity.
• Materials : Tip uses Polyphenylene sulfide (PPS). Case is AISI 304 stainless steel (SST).
• Magnetic Field Immunity : At 50 mil gap, probe generates only 0.0014 mil pp/gauss in 60 Hz fields up to 300 Gauss.
• Tensile Strength : 222 N (50 lbf) for case-to-lead and connector joints.

Mechanical & Installation Details

• Thread Data : 1/4-28 UNF. Maximum thread engagement is 0.375 in. Use #3 or larger tap drill for mounting holes.
• Overall Case Length : 9.4 inches (suffix 94) – ideal for reaching measurement points through thick machine casings or insulation.
• Unthreaded Length : 0 inches (suffix 00) – threads start immediately at the probe tip.
• Probe Case Torque : Recommended 5.1 N·m (45 in·lb). Maximum allowable is 7.3 N·m (65 in·lb).
• Connector Torque : Do not exceed 0.565 N·m (0.42 ft·lbf) when mating ClickLoc connectors.
• Connector Type : Miniature coaxial ClickLoc (Option 02) without protector for standard installations.
• Cable Specifications : 75 Ω triaxial, FEP insulated. Minimum bend radius is 25.4 mm (1.0 in).
• Available Cable Lengths : 0.5, 1, 2, 5, or 9 meters (1.6 to 29.5 feet).

Frequently Asked Questions (FAQ)

• What is the benefit of the 9.4-inch case length?
  Suffix 94 provides an extra-long 9.4-inch case, allowing you to reach measurement points through thick machine walls, insulation, or standoff brackets.
• Can I use the 330172-00-94-10-02-00 with standard extension cables?
  Yes, the ClickLoc interface (Option 02) mates directly with all Bently Nevada 3300 series extension cables.
• What does "Agency Approval Option 00" mean?
  It means this probe ships without hazardous location certifications, making it ideal for general-purpose monitoring where approvals are not required.
• Is the probe tip field-replaceable?
  No, the PPS tip is integrally molded to the stainless steel case for maximum durability and reliability.
• How soon can Ubest Automation ship this item?
  We maintain stock and ship within 24 hours via FedEx, UPS, or DHL.
