Case Length and Unthreaded Length Rules

• Case length: 8.0 inches (203.2 mm) from mounting shoulder to tip.
• Unthreaded length: 1.0 inch (25.4 mm).
• Critical rule: Unthreaded length must be 0.8 inches less than case length.
• Verification: 8.0 inch case - 1.0 inch unthreaded = 7.0 inch difference.
• Requirement met: 7.0 inches exceeds required 0.8 inches by large margin.
• Threaded portion: 7.0 inches available for mounting through thick walls.

Long Reach Design Benefits

• 8.0 inch case: Reaches through very thick machine casings.
• 1.0 inch unthreaded: Provides tip clearance from mounting threads.
• 9.0 meter cable: Spans long distance from probe to proximitor.
• Typical application: Large turbines with thick insulation layers.
• Deep recessed ports: Reaches probe tips below mounting surface.
• No extension rod needed: One-piece design eliminates connection points.

Frequently Asked Questions

• Q: What applications need the 8.0 inch case 330192-10-80-90-CN probe?
  A: Use this long case probe for very thick machine casings, typically over 6 inches thick. Common applications include large steam turbines, gas compressors with insulation, and deep recessed mounting ports where standard probes cannot reach the shaft.
• Q: Is the 1.0 inch unthreaded length correct for this 8.0 inch case?
  A: Yes. The rule requires unthreaded length to be at least 0.8 inches less than case length. With 8.0 inch case and 1.0 inch unthreaded, the threaded portion is 7.0 inches. This provides plenty of thread engagement for thick wall mounting.
• Q: What does the 9.0 meter cable length mean for system configuration?
  A: The 9.0 meter cable allows the proximitor to mount far from the probe. Total system length (probe cable + extension cable) must match the proximitor calibration. With 9.0 meter built-in cable, you may not need an external extension cable.
• Q: What are the temperature class ratings for 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 330192-10-80-90-CN below -34°C (-30°F)?
  A: Bently Nevada warns that exposure below -34°C may cause premature pressure seal failure. For cold environments, consider the extended temperature range probe option or contact Bently about special sealing materials for low temperature operation.
