• External Thread: 1/2-14 NPT
• Overall Length: 38.1 mm (1.50 in)
• Material: 304 Stainless Steel
• Measurement Range: Depends on probe type; adapter supports standard proximity probes.
• Frequency Response: Limited by probe; adapter introduces minimal mechanical resonance.
• Sensitivity: No electrical signal degradation; full probe sensitivity retained.
• Linearity: Mechanical alignment ensures < 0.1% deviation.
• Resolution: Mechanical fit does not affect probe resolution.
• Temperature Range: -30 °C to +120 °C (continuous operation).
• Environmental Tolerance: IP67-rated when properly installed.
• Immunity: No electrical interference; passive mechanical part.

Installation Guide

• Clean both adapter threads and machine ports before installation.
• Apply thread sealant (not included) to 1/4-18 NPT side.
• Hand-tighten adapter into junction box, then torque to 20 N·m.
• Attach proximity probe to the 1/2-14 NPT external thread.
• Verify probe gap and secure locking nut.

Debugging & Maintenance

• Inspect threads for debris or damage every 6 months.
• Recalibrate probe after any adapter reinstallation.

• Gearbox and motor proximity sensing.
• Retrofit for legacy Bently Nevada systems.

FAQ

• Can I use this adapter with a non-Bently probe?
  Yes, as long as the probe has 1/2-14 NPT thread. Check probe dimensions.
• Is the adapter field-repairable?
  No. Replace if threads are damaged. It is a single-piece stainless part.
• Does it include a gasket?
  No, but an O-ring is included in the package for a tight seal.
• What torque should I apply?
  20 N·m for initial installation. Re-torque after 24 hours of operation.
• Can I paint or coat the adapter?
  Avoid coatings that may alter thread dimensions. Use as-is.

Selection Guide

• For high-temperature zones (>100 °C), choose 4190-01 (standard).
• For offshore/chlorine environments, 304 SS provides excellent corrosion resistance.
• If your junction box has British threads, request a custom variant.
• Always measure your existing probe thread before ordering.
