• Extended Temp Range: Tip: Up to +218°C (+425°F); Cable: Up to +260°C (+500°F).
• Relative Humidity: <3% ASF change at 93% humidity per IEC 68-2-3.
• Intrinsic Safety: Available (AEx/Ex ia IIC) with appropriate barriers.

Installation & Wiring Guidelines

• Use 3-conductor shielded triad cable with tinned wiring (0.2 to 1.5 mm² / 16-24 AWG).
• Maximum field wiring distance: 305 meters (1,000 feet) between sensor and monitor.
• Maximum thread engagement for 3/8-24 UNF case is 0.563 inches.
• Avoid exposing probes to temperatures below -34°C (-30°F) to protect the pressure seal.

Frequently Asked Questions (FAQ)

• Q: Can I use a 5-meter cable with any monitor?
  A: No. 5-meter probes pair only with the 5-meter Proximitor sensor.
• Q: What is the default probe gap setting?
  A: Set the gap to achieve -9 Vdc, which is roughly 1.27 mm from the target.
• Q: Are these probes pressure tested?
  A: No. For pressure seal validation, please contact Bently Nevada's custom design department.
