• DC resistance (RPROBE): 5.9 ± 0.5 Ω (center to outer conductor)

Diagnostics & Calibration

Diagnostic capability: Built-in coil resistance check validates probe integrity. Use with Bently Nevada proximity systems for real-time gap voltage monitoring.

Calibration: Factory calibrated per ISA standards. Re-calibration recommended every 12 months or after severe mechanical shock.

Compatibility & Certification

• Compatible systems: Bently Nevada 3500, 1900, and 2300 monitoring systems
• Approvals: Multiple approvals (option 05) – ATEX, IECEx, CSA, and more
• Temperature classifications (EPL Ga/Gc): T1 to T5 (-55°C to +232°C)
• EPL Dc: T280°C @ Ta (-55°C to +232°C) … T90°C @ Ta (-55°C to +40°C)

Maintenance & Service Friendly

Simple connector-to-connector torque (finger tight) reduces installation time. The PPS tip resists chemical attack. FEP cable insulation offers excellent dielectric strength. Accessible for in-situ gap adjustment.

Frequently Asked Questions (FAQ)

• Q: Can this probe operate in high-pressure environments?
  A: Yes, the Viton O-ring seals differential pressure. Contact us for pressure seal testing.
• Q: What is the minimum bend radius for the cable?
  A: 25.4 mm (1.0 in) – even with stainless steel armor.
• Q: Is the probe compatible with 3300 XL extension cables?
  A: Yes, it uses standard 75 Ω triaxial cables with ClickLoc connectors.
• Q: How do I verify the probe health?
  A: Measure DC resistance between center and outer conductor – nominal 5.9 Ω ±0.5.
• Q: What temperature classification for hazardous areas?
  A: Multiple T-classes available, see technical data above.
