Installation Guidelines for 3300 XL 50 mm Probe

• Probe uses two #2-56 UNC mounting holes on the rear side.
• Center-to-center spacing equals 0.75 inch (19 mm) for secure mounting.
• Recommended thread torque range: 7–10 in-lb (0.8–1.1 N·m).
• Do not exceed the torque value to prevent thread damage.
• Maintain a cable bend radius no less than 25 mm (1 inch).
• Use proper grounding for the triaxial cable to ensure signal integrity.
• Always verify clearance before tightening the mounting screws.

Environmental Tolerance & Noise Immunity

• The 330876-01-50-00-CN probe withstands high humidity and oil exposure.
• FluidLoc cable resists fluid ingress and abrasion in severe zones.
• Triaxial design provides excellent common-mode noise rejection.
• Operating temperature range covers most steam turbines and generators.
• Short-term 250°C capability handles occasional thermal spikes.
• PPS tip resists many chemicals and offers stable thermal performance.
