Key Product Advantages & Selling Points

• The FluidLoc cable actively prevents oil migration into your machine.
• Hazardous area approvals (CSA/ATEX/IECEx) allow use in classified locations.
• The connector protector guards against physical damage during installation.
• A patented TipLoc molding process gives the tip superior bond strength.
• The 8mm thick body offers the best protection against accidental impacts.
• The CableLoc strain relief withstands over 75 pounds of pull force.

Expert FAQs for the 3300 XL Probe

• What is the main benefit of the FluidLoc cable option? It seals the cable core to stop lubricant or process fluid from wicking along it, preventing internal machine leaks and preserving signal integrity.
• Why does the probe have a minimum operating temperature of -34°C? Below this point, the elastomeric pressure seal (Viton® O-ring) can become brittle and may fail, compromising the probe's environmental sealing.
• Can I use this probe for axial (thrust) position measurement? Yes, you can use it for axial measurement. However, you must set the gap within the linear range and account for the system's calibration and setup for position monitoring.
• What does the "connector protector" option provide? This rigid sleeve threads onto the connector body, protecting the delicate coaxial pins from impact, dust, and moisture during handling and before final connection.
• How does the thicker 8mm design improve reliability? It allows for a thicker layer of protective PPS plastic over the sensing coil, significantly increasing its resistance to physical wear, abrasion, and mechanical impact compared to smaller probes.
