Product Specifications

Key Features

Patented TipLoc molding provides robust bond between probe tip and body. CableLoc design delivers 330 N (75 lbf) pull strength. Thicker PPS encapsulation of probe coil for enhanced ruggedness. Larger diameter probe body provides stronger, more durable case. Optional FluidLoc cable prevents oil leakage through cable interior. CN approval for country specific hazardous area requirements. 8mm design recommended for optimal robustness against physical abuse.

Installation Notes

Mount probe with 3/8-24 UNF thread. Set initial gap to -9 Vdc (approximately 1.27 mm / 50 mils) for radial vibration monitoring. Use 3-conductor shielded triad cable for field wiring (16-24 AWG). Maximum field wiring length 305 m (1,000 ft). Ensure temperature does not drop below -34°C (-30°F) to prevent pressure seal failure. For oil leak prevention, specify FluidLoc cable option.

Engineering Advantages

8mm probe design delivers thicker PPS encapsulation for superior durability in harsh environments. TipLoc and CableLoc technologies prevent common failure modes. Linear range from 0.25 to 2.3 mm (10-90 mils) provides broad measurement capability. 7.87 V/mm scale factor with ±5% interchangeability error ensures consistent performance. CN approval enables installation in country specific hazardous areas. Compatible with 3300 XL Proximitor Sensor and monitoring systems.

FAQs

Q1: What does the CN suffix indicate?
A1: CN denotes Country Specific Approval, certifying the probe for hazardous area installations in specific countries. Verify local approval requirements before ordering.

Q2: What is the recommended gap setting for radial vibration?
A2: Recommended gap is -9 Vdc, which corresponds to approximately 1.27 mm (50 mils) from the target surface.

Q3: Can this probe be used with extension cables?
A3: Yes, the 3300 XL system supports extension cables. Total system length (probe + extension cable) must be 5, 7, or 9 meters for standard configurations. Capacitance is 69.9 pF/m typical.
