Global PLC Spare HUB's Insight

• The 173687-01-50-12-05 is a specialized variant designed for high-seal integrity.
• The -12 FluidLoc cable is a deliberate choice for applications where the probe lead is exposed to high-pressure oil.
• This prevents fluid migration into connection housings, significantly improving safety in hazardous area zones.

Diagnostic Capabilities & Application Scope

• Signal Accuracy: Provides a linear scale factor of 7.87 V/mm (200 mV/mil) when properly gapped.
• Fault Detection: DC Gap Voltage monitoring allows for rapid identification of cable shorts or physical displacement errors.
• Suitable Equipment: Large steam turbines, centrifugal compressors, and high-speed gearboxes.
• Common Uses: Radial vibration monitoring and axial thrust position sensing.

Commercial & Logistics Terms

• Dispatch Window: Dispatched within 24-48 hours via FedEx, UPS, or DHL.
• Warranty: Includes a comprehensive 12-month factory-standard quality guarantee.
• Authenticity: Guaranteed genuine Made in U.S.A hardware in original packaging.

Professional FAQ & Selection Guidance

• Why choose the FluidLoc (-12) cable?
• It prevents process fluids from migrating through the cable core, maintaining the explosion-proof integrity of junction boxes.
• Is the 5.0m system length compatible with a 9.0m Proximitor?
• No. This probe is match-tuned for a 5-meter system; mixing lengths will cause Scale Factor errors.
• What is the benefit of the PPS tip?
• PPS is chemically resistant and thermally stable, ensuring the probe remains accurate in oily industrial environments.
• Can this probe be used in Zone 0?
• Yes, the -05 suffix indicates ATEX and IECEx approvals for hazardous locations.
• Does it require a separate O-ring for sealing?
• The 173687-01-50-12-05 comes with an integrated Viton O-ring for standard pressure sealing applications.
