Key Technical Specifications

• Measurement Range : Optimized for AISI 4140 steel target, gapped at 1.27 mm (50 mils).
• Sensitivity & Linearity : Less than 2 mV change per volt change. System operates with -24 Vdc supply and 10 kΩ load.
• Electrical Power : 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 (1.0 m length) from center to outer conductor.
• Temperature Range : -35°C to +177°C (-31°F to +351°F). Avoid exposing below -34°C to protect pressure seal.
• Environmental Tolerance : Probe tip uses Polyphenylene sulfide (PPS). Case material is AISI 304 stainless steel.
• 60 Hz Magnetic Field Immunity : Output as low as 0.0004 mil pp/gauss (probe only) at 10 mil gap. System performance varies with gap.
• Tensile Strength : 222 N (50 lbf) for case-to-lead and lead-to-extension cable connectors.

Mechanical & Installation Details

• Thread Specification : 1/4-28 UNF. Maximum thread engagement is 0.375 in. Use a #3 or larger tap drill for mounting.
• Probe Case Torque : Recommended 5.1 N·m (45 in·lb). Maximum allowable torque is 7.3 N·m (65 in·lb).
• Connector-to-Connector Torque : Maximum 0.565 N·m (0.42 ft·lbf).
• Minimum Cable Bend Radius : 25.4 mm (1.0 in).
• Cable Type : 75 Ω triaxial, FEP insulated, available in lengths up to 9 meters.
• Connector Material : Gold-plated brass or beryllium copper for secure signal transmission.

Frequently Asked Questions (FAQ)

• What target material does the 330172 use?
  Factory calibrated for AISI 4140 steel. You can use other targets but linearity may vary.
• Can I use this probe with an extension cable?
  Yes, the ClickLoc connector (Option 01) mates directly with Bently Nevada extension cables. Maintain 75 Ω impedance.
• What is the maximum thread engagement length?
  Maximum engagement is 0.375 in. Do not exceed this to avoid damaging the probe case.
• Does this probe work with 3300 XL proximitors?
  Yes, the 330172-00-28-10-01-05 is designed for 5mm systems and works with XL series proximitors.
• What is the delivery time?
  We ship from stock via FedEx, UPS, or DHL. Most orders arrive within 3-5 business days.
