• Measurement type: Center conductor to outer conductor resistance.
• Cable impedance: 75 Ω coaxial for system matching.
• Linear range: 2 mm (80 mils) standard 3300 XL performance.
• Sensitivity: 7.87 V/mm (200 mV/mil) at nominal gap.
• Frequency response: 0 to 10 kHz DC coupled.

Temperature Specifications

• Standard operating range: -52°C to +177°C (-62°F to +350°F).

Frequently Asked Questions

• Q: What makes the 330192-00-60-10-00 different from shorter or longer probes?
  A: This probe has 6.0 inch case length with zero unthreaded section. It fits medium thickness casings where 5 inch is too short and 8 inch is excessive. The 1.0 meter cable suits proximitors mounted near the machine.
• Q: Is zero unthreaded length acceptable for this probe?
  A: Yes. The rule requires unthreaded length to be at least 0.8 inches less than case length. With 6.0 inch case and 0.0 inch unthreaded, the threaded portion is 6.0 inches. This far exceeds the 0.8 inch requirement.
• Q: What does the 1.0 meter cable mean for installation?
  A: The 1.0 meter built-in cable connects directly from probe to proximitor. For longer distances, add a 3300 XL extension cable. Total system length (probe cable + extension) must match the proximitor calibration label.
• Q: What temperature class ratings apply to this probe?
  A: For gas environments (EPL Ga/Gc), ratings range from T1 (-55°C to +232°C) down to T5 (-55°C to +40°C). For dust environments (EPL Dc), surface temperatures vary from 280°C down to 90°C depending on ambient temperature range.
• Q: Can I use the 330192-00-60-10-00 in freezing conditions?
  A: The probe operates down to -52°C, but Bently Nevada warns that exposure below -34°C may cause premature pressure seal failure. For sustained cold operation below -34°C, contact Bently about special sealing options or extended temperature range probes.
