Technical Specifications

• Brand: Bently Nevada
• Model: 330171-00-08-10-02-CN
• System Power: Requires -17.5 Vdc to -26 Vdc at 12 mA maximum consumption.
• Supply Sensitivity: Less than 2 mV output change per 1V input change.
• Output Resistance: 50 Ω
• Probe DC Resistance (1.0m length): 7.59 Ω ± 0.50 (center to outer conductor).
• Cable Type: 75 Ω triaxial, FEP insulated (lengths: 0.5, 1, 2, 5, or 9 meters).
• Probe Temperature Range: -35°C to +177°C (-31°F to +351°F).
• Below -34°C (-30°F): May cause premature pressure seal failure.
• 60 Hz Magnetic Field Immunity (300 Gauss): Probe + cable output ≤0.0045 mV pp/gauss at 90 mil gap.
• Tensile Strength: 222 N (50 lbf) from probe case to lead, and lead to extension cable.
• Connector Material: Gold-plated brass or gold-plated beryllium copper.

Shipping & FAQ

• Carriers: FedEx, UPS, DHL – worldwide express available.
• Q: Does this probe work with AISI 4140 steel targets?
  • A: Yes. The specifications use AISI 4140 steel at 1.27 mm (50 mils) gap.
• Q: What voltage range maintains full linear range?
  • A: Use -23.5 Vdc or more negative. A more positive voltage reduces linear range.
• Q: Can I replace the cable on the 330171 series?
  • A: No. The probe has an integrated 75 Ω triaxial cable.
• Q: Is this probe suitable for high magnetic fields?
  • A: Yes. The system tolerates up to 300 Gauss at 60 Hz with minimal noise.
• Q: What does the "CN" approval mean?
  • A: "CN" indicates country-specific approvals for China.
