  • Unthreaded Length: 0.0 inches (Option 00).
  • Overall Case Length: 2.0 inches (Option 20).
  • Total Probe Length: 5.0 meters (16.4 feet, Option 50). Note: Five meter probes work only with the five meter Proximitor Sensor.
  • Connector Type: Miniature coaxial ClickLoc connector, FluidLoc cable (Option 12).
  • Agency Approval: Not required (Option 00).
  • Probe Tip Material: Polyphenylene sulfide (PPS).
  • Probe Case Material: AISI 304 stainless steel (SST).
  • Cable Specification: 75 Ω triaxial cable with FEP insulation. Available total lengths: 1, 5, or 9 meters.
  • Operating & Storage Temperature: -51°C to +177°C (-60°F to +351°F).
  • Probe Pressure Seal: Viton O-ring design. It seals differential pressure between tip and case.
  • DC Resistance (Probe length 5.0m): 7.2 ± 0.8 ohms from center conductor to outer conductor.
  • Case Thread Engagement Max Length (1/2-20): 0.750 inch.
  • Recommended Probe Case Torque: 15.2 N•m (133 in•lb). Maximum rated torque: 45.2 N•m (400 in•lb).
  • Connector Torque: Finger tight recommended; Maximum 0.565 N•m (5 in•lb).
  • Minimum Bend Radius (with or without SST armor): 25.4 mm (1.0 inch).
  • Temperature Warning: Exposing the probe below -34°C (30°F) may cause premature pressure seal failure.
  • Temperature Schedule for EPL Ga/Gc: T1 up to 232°C, T2 up to 177°C, T3 up to 120°C, T4 up to 80°C, T5 up to 40°C.
  • Temperature Classification for EPL Dc: T280°C, T225°C, T170°C, T130°C, T105°C, T90°C at respective Ta.
  • Shipping Weight: 0.17 Kg.

Installation & Handling Guidelines

  • Do not exceed maximum torque 45.2 N•m on the 1/2-20 probe case.
  • Apply recommended torque of 15.2 N•m (133 in•lb) for safe mounting.
  • Use maximum thread engagement of 0.750 inch for 1/2-20 UNF threads.
  • Keep minimum bend radius at 25.4 mm to avoid cable damage.
  • Only finger-tighten the ClickLoc connector; do not exceed 0.565 N•m torque.
  • This 5.0 meter probe requires a compatible five meter Proximitor Sensor.
  • Avoid operating below -34°C to protect the Viton pressure seal.

Environmental & Mechanical Durability

  • Armored construction: Provides extra mechanical protection for harsh industrial environments.
  • Wide temperature range: -51°C to +177°C for reliable use in extreme conditions.
  • FluidLoc cable (Option 12): Offers enhanced fluid resistance against oil and coolant exposure.
  • Probe cable with FEP insulation: Provides excellent chemical and thermal resistance.
  • Stainless steel case (AISI 304): Resists corrosion and mechanical stress.
  • Triaxial 75 Ω cable design: Improves signal integrity and reduces external interference.
  • Viton O-ring seal: Maintains differential pressure integrity.

Frequently Asked Questions (FAQ)

  • Is the 330707-00-20-50-12-00 a genuine Bently Nevada probe?
