Engineering Advantages

• Superior Mechanical Armor: The integrated stainless steel armor protects the coaxial cable from crushing, abrasion, and accidental cutting. This ensures signal continuity in high-traffic maintenance areas where standard cables often suffer damage.

• Connector Protector Integration: The "Option 11" configuration includes a specialized connector protector. This prevents moisture, oil, and dust from entering the coaxial connection point, which is a common cause of signal "spikes" and measurement drift in humid or oily turbine environments.

• Global Explosion-Proof Compliance: The "-05" multi-approval rating covers CSA, ATEX, and IECEx standards. This allows engineers to standardize on a single probe model for global fleets, ensuring safety compliance across different regional regulatory jurisdictions.

• ClickLoc™ Interconnect Security: The gold-plated ClickLoc™ system employs a self-locking mechanism. It prevents the cable from backing out due to high-frequency machine vibration, maintaining a gas-tight, low-resistance electrical path essential for accurate 200 mV/mil sensitivity.

• High-Density Metric Mounting: The 50mm fully threaded case offers maximum gapping flexibility. This allows for precise positioning in varying machine casing thicknesses, ensuring the probe tip resides at the exact electrical center of the linear range.

FAQs

Q: Why does this probe only have a 0.5-meter total length?

A: This "short-lead" design minimizes the cable length inside the machine casing. You must connect this probe to a 3300 XL Extension Cable outside the casing to reach your Proximitor® Sensor. The total system length (typically 5.0m or 9.0m) must match the Proximitor's calibration.

Q: Can I use this probe with an older 7200 series Proximitor?

A: No. To maintain 3300 XL performance and 200 mV/mil scale factor accuracy, you must pair this probe with a 3300 XL Proximitor Sensor and a 3300 XL Extension Cable.

Q: What is the primary benefit of the connector protector?

A: In oily or humid environments, contaminants can bridge the coaxial signal. The connector protector acts as a physical barrier, ensuring the gold-plated ClickLoc™ connection remains dry and uncontaminated, which prevents false vibration trips.

Q: Does the armor affect the minimum bend radius of the cable?

A: While the armor increases durability, it does make the cable stiffer than non-armored versions. We recommend a minimum bend radius of 25.4 mm (1.0 inch) to ensure the internal coaxial core remains undamaged during routing through conduit.
