Core Technical Specifications

• Measurement Range : Factory calibrated for AISI 4140 steel target at 1.27 mm (50 mils) gap.
• Sensitivity & Linearity : Less than 2 mV change per volt of supply variation. System uses -24 Vdc supply with 10 kΩ load.
• Power Requirements : Requires -17.5 Vdc to -26 Vdc at 12 mA maximum consumption. 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 protect 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.
• Unthreaded Length : 1.2 inches (suffix 12) provides flexibility for different mounting configurations.
• 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 with protector (Option 01) for reliable connections in harsh environments.
• 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).
• Connector Material : Gold-plated brass or beryllium copper for corrosion-resistant signal transfer.

Frequently Asked Questions (FAQ)

• What does the "12" unthreaded length option mean?
  Suffix 12 provides 1.2 inches of smooth shaft before the threaded portion, allowing you to adjust insertion depth without engaging threads.
• Can I use the 330172-12-23-10-01-05 with existing 3300 extension cables?
  Yes, the ClickLoc interface (Option 01) mates directly with standard Bently Nevada 3300 series extension cables.
• What approvals does suffix 05 include?
  Suffix 05 provides Multiple Approvals including ATEX, IECEx, and CSA for use in hazardous locations. Refer to certificate for specific gas groups.
• 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.
