Expert Review & Manager’s Insight

The 330191-00-08-50-CN is specifically engineered for 5 meter Proximitor systems. The 0.8in short case fits tight installations while the 5.0m cable reaches remote monitors. CN approval makes it ideal for China projects. Critical note: This probe must ONLY be used with 5 meter Proximitors – mismatching lengths causes calibration errors. For shallow mounting with long cable reach, this is our recommended choice.

Applications & Compatible Devices

• Compressors with shallow case depths (0.8in)
• Turbines needing 5m remote monitoring
• Machinery with 5 meter Proximitor systems
• China-based projects requiring CN approval
• Any installation requiring 5.0m cable with short case

Frequently Asked Questions (FAQ)

• What is special about this 5.0m probe?This probe is designed EXCLUSIVELY for 5 meter Proximitor sensors. Using it with other proximitors will give incorrect readings. Check your system compatibility.
• What is the DC resistance for this model?8.73 Ω ± 0.50 from center to outer conductor. This matches 5 meter system calibration requirements.
• Why choose 0.8in case length (Option 08)?0.8in is the shortest case available. Perfect for thin machine casings or where space is limited behind the mounting hole.
• Difference between 330191-00-08-50-CN and 330191-00-70-90-00?-00-08-50-CN: 0.8in case, 5.0m cable, CN approval.
  -00-70-90-00: 7.0in case, 9.0m cable, no approval. Choose based on case depth, cable length, and certification needs.
• Can I use this probe with armored cable?Armor is optional and must be ordered separately. This standard version has FEP insulation without armor.
