330171-08-24-10-02-00 Bently Nevada 5mm Probe Proximity Sensor

Bently Nevada 330171-08-24-10-02-00 5mm Probe Overview

Key Electrical & System Specifications

• Power requirement: Requires a -17.5 Vdc to -26 Vdc supply at 12 mA maximum. Operation above -23.5 Vdc reduces linear range.
• Sensitivity to supply variation: Less than 2 mV output change per volt of input change. This ensures stable readings.
• Output resistance: 50 Ω for standard load compatibility. Works with a 10 kΩ load during specified tests.
• Probe DC resistance: For 1.0 meter length, center to outer conductor resistance is 7.59 ± 0.50 Ω.
• Cable type: 75 Ω triaxial with fluoroethylene propylene (FEP) insulation. Standard cable length is 1.0 metre (3.3 feet).
• Connector option: Miniature coaxial ClickLoc connector (code 02) on standard cable.

Mechanical Dimensions & Thread Details

• Unthreaded length option: 0.8 inch (code 08). Allows proper gap adjustment.
• Overall case length option: 2.4 inches (code 24). Provides robust housing.
• Total length option: 1.0 metre (3.3 feet) – code 10. Flexible for many installations.
• Probe case thread: 1/4-28 UNF. Maximum thread engagement length is 0.375 inch.
• Recommended tap drill: #3 or larger for mounting hole. Follow this to avoid damage.
• Probe case torque: Recommended 5.1 N·m (45 in·lb). Maximum 7.3 N·m (65 in·lb).
• Connector-to-connector torque: Recommended max 0.565 N·m (0.42 ft·lbf). Prevents over-tightening.
• Minimum cable bend radius: 25.4 mm (1.0 inch). Protects the FEP insulation.

Material Composition & Environmental Tolerance

• Probe tip material: Polyphenylene sulfide (PPS). Excellent chemical and heat resistance.
• Probe case material: AISI 304 stainless steel (SST). Withstands corrosion and mechanical stress.
• Connector material: Gold-plated brass or gold-plated beryllium copper. Ensures low contact resistance.
• Temperature range (probe only): -35°C to +177°C (-31°F to +351°F). Avoid below –34°C to protect pressure seal.
• Agency approval option: Code 00 for standard approvals. Meets industrial safety standards.
• Temperature classification T1 to T5: Ambient from -55°C up to +232°C depending on class. Refer to temperature schedule.
• For EPL Dc: Ratings like T280°C @ Ta up to +232°C. Flexible for hazardous areas.

Magnetic Field Immunity & Performance Data

• 60 Hz magnetic field effect: Up to 300 Gauss (5m system). Output voltage in mil pp/gauss varies by gap.
• At 10 mil gap: XL Proximitor Sensor shows 0.0119; Probe shows 0.0004; XL Ext. Cable shows 0.0004.
• At 50 mil gap: XL Proximitor Sensor 0.0131; Probe 0.0014; Ext. Cable 0.0014. Excellent noise rejection.
• At 90 mil gap: XL Proximitor Sensor 0.0133; Probe 0.0045; Ext. Cable 0.0045. Maintains low interference.
• This 330171-08-24-10-02-00 probe shows reliable output even near strong magnetic fields.

Frequently Asked Questions (FAQ)

• Q: Is this 330171-08-24-10-02-00 a new original Bently Nevada probe?
  A: Yes, absolutely. We supply only brand new, factory-sealed units. No used or third-party copies.
• Q: What is the exact unthreaded length of this model?
  A: The unthreaded length option 08 equals 0.8 inch. This allows proper gap setting without thread interference.
• Q: Can I use this probe at temperatures below -30°F?
  A: The probe works from -35°C to +177°C. However, exposing it below –34°C (-30°F) may cause premature pressure seal failure. Follow the temperature schedule carefully.
• Q: What is the recommended torque for mounting?
  A: Recommended torque is 5.1 N·m (45 in·lb). Maximum allowed torque is 7.3 N·m (65 in·lb). Exceeding this damages the probe case.
• Q: How long does shipping take?
  A: We dispatch within 5 days. Express shipping via FedEx, UPS, or DHL usually takes 3-7 business days depending on destination.
• Q: Do you offer returns?
  A: Yes, we support 30-day returns for unused items. Contact us first for return authorization.
• Q: What power supply works best with this proximity probe?
  A: Use a -24 Vdc supply at 12 mA maximum. Operation more positive than -23.5 Vdc reduces linear range, so maintain -17.5 to -26 Vdc.
• Q: What is the agency approval option for this product?
  A: Code 00 means standard agency approval. Suitable for many industrial and hazardous locations based on temperature classification.
• Q: Can I extend the cable length?
  A: Bently Nevada offers extension cables; this probe has a 1.0 meter fixed cable. Use compatible 75Ω triaxial extension with proper connectors.
• Q: What is the thread size and maximum engagement?
  A: Thread is 1/4-28 UNF. Maximum length of thread engagement is 0.375 inch (9.5 mm). Always respect this limit.
