Core Technical Parameters & Performance Data

• Electrical Output: The system provides a precise −7.87 V/mm (−200 mV/mil) scale factor.
• Frequency Response: 0 to 10 kHz for capturing both slow rolls and high-speed events.
• Linear Range: Typically 0.25 to 2.3 mm (10 to 90 mils) from the probe tip.
• Probe Gap Voltage: A stable −10 V DC bias with a −2 to −18 V measurement range.
• Temperature Stability: Operates from -51°C to +177°C without signal drift.
• Electrical Resistance (5m): 7.2 ± 0.8 ohms from center conductor to outer conductor.
• Shield & Insulation: 75 Ω triaxial design with FEP insulation for superior noise immunity.

Robust Construction & Key Product Advantages

• Armored Defense: Stainless steel cable armor protects against abrasion and crushing.
• Extended Reach: The 5-meter length allows flexible routing on large turbines and motors.
• Environmental Seal: A Viton O-ring keeps contaminants away from sensitive electronics.
• Corrosion Resistance: The entire case uses durable AISI 304 stainless steel.
• Secure Connection: The ClickLoc connector ensures a vibration-proof, positive lock.
• Note: This Bently Nevada 330707-00-15-50-01-CN requires a matching 5-meter Proximitor sensor.

Expert Answers to Common Questions

• Q: Why does this 5-meter probe require a specific Proximitor? A: The cable length affects system calibration. The 5-meter Proximitor contains matching compensation circuits for accurate readings.
• Q: What is the primary benefit of the armored cable? A: The armor provides exceptional physical protection in high-risk areas with moving parts or debris.
• Q: Can I cut the cable to a shorter length if needed? A: No. Cutting the cable will destroy its calibration and electrical characteristics. Always order the correct length.
• Q: How does the "Country Specific Approval" suffix affect use? A: This means the probe meets particular regional safety and EMC standards, which is crucial for compliant installations.
• Q: What maintenance does the probe's pressure seal require? A: The Viton O-ring is maintenance-free but inspect it during routine checks for any signs of hardening or damage.
