Engineering Advantages

The 330104-00-08-50-12-00 solves specific mechanical and environmental challenges common in turbine and gearbox monitoring:

• Fluid Migration Prevention: The FluidLoc® cable design prevents oil or other process fluids from wicking through the inside of the cable. This protects the Proximitor® sensor and terminal housing from contamination in oil-saturated environments.

• Secure Signal Path: The ClickLoc™ connector features a robust locking mechanism that eliminates the risk of disconnection caused by machine-induced resonance or high-frequency vibration.

• Extended Reach: The 5.0-meter total length enables direct routing from the machine bearing to a local junction box, removing the need for an additional extension cable and reducing potential signal failure points.

• Precision Mounting: The 80mm fully threaded case allows for precise gap adjustments in thick-walled bearing housings, ensuring the probe tip resides perfectly within the linear measurement range.

FAQs

• What is the primary benefit of the FluidLoc® cable option?

  Standard cables can act as a "straw," allowing pressurized oil to migrate through the cable jacket into the Proximitor® housing. FluidLoc® technology seals the internal cable structure to block this migration path, significantly increasing system lifespan.

• Does this probe require a specific Proximitor®?

  Yes, this probe must pair with a 3300 XL Proximitor® calibrated for a 5.0-meter system. Using a 9.0-meter Proximitor will result in incorrect scale factor readings.

• How do I confirm the probe is properly gapped?

  Use a digital multimeter to monitor the DC voltage at the Proximitor output. Rotate the probe in the mounting thread until the voltage reads -10.0 Vdc (representing the center of the 80-mil linear range) before securing the locknut.

• Is this probe interchangeable with older 3300 series models?

  Yes. The 3300 XL 8mm probe maintains full physical and electrical backward compatibility with legacy 3300 series components, though we recommend the XL Proximitor for improved temperature stability.
