between the probe tip and the shaft surface. Technicians must utilize a digital multimeter to monitor the DC output voltage at the Proximitor Sensor. For a standard 3300 XL 8mm system, the probe should be gapped to -10.0 VDC (the midpoint of the linear range), which typically equates to a physical distance of 1.27 mm (50 mils). Avoid over-tightening the probe within the mounting bracket; hand-tighten first, then secure with the locking nut to prevent case deformation. Ensure the coaxial cable maintains a minimum bend radius of 25.4 mm (1.0 inch) to protect the signal integrity of the high-frequency carrier wave.\u003c\/p\u003e\n\u003ch2\u003eOperational Durability and Integration\u003c\/h2\u003e\n\u003cp\u003eThe 330101-00-25-20-12-05 excels in extreme environments characterized by high thermal stress and corrosive lubricants. Its Polyphenylene Sulfide (PPS) tip resists chemical degradation, while the 304 stainless steel case ensures mechanical longevity within the bearing housing. This probe integrates seamlessly with Turbine Supervisory Instrumentation (TSI) suites and Honeywell Experion PKS, enabling advanced machinery diagnostics and automatic emergency shutdown (ESD) capabilities. By providing a stable, noise-immune signal, it reduces false-trip incidents and ensures that the protection system only intervenes during genuine mechanical hazards.\u003c\/p\u003e\n\u003ch2\u003eDelivery and Packaging Information\u003c\/h2\u003e\n\u003cp\u003eDelivery time: 3-5 days when payment finish, BY DHL\/FEDEX\/UPS.\u003c\/p\u003e\n\u003cp\u003eWe dispatch all Bently Nevada probes in factory-sealed, anti-static industrial packaging.

For a 9.0-meter system, pair it with a 7.0-meter extension cable.\u003c\/p\u003e\n\u003cp\u003eQ2: Does the \"12\" suffix provide extra protection against oil?\u003c\/p\u003e\n\u003cp\u003eA2: Yes, the \"12\" option includes the FluidLoc seal, which prevents lubrication oil from leaking through the cable's interior, a critical feature for high-pressure bearing applications.\u003c\/p\u003e\n\u003cp\u003eQ3: Can this probe be used with a target material other than 4140 Steel?\u003c\/p\u003e\n\u003cp\u003eA3: The probe is factory-calibrated for AISI 4140 steel. If your shaft uses a different alloy, you must apply a scale factor correction in your monitor configuration to account for differences in magnetic permeability.\u003c\/p\u003e\n\u003cp\u003eQ4: Is the click-lock connector moisture-proof?\u003c\/p\u003e\n\u003cp\u003eA4: While the connector provides a secure mechanical lock, we recommend using Fluorosilicone connector protectors or heat-shrink tubing in environments with high humidity or oil mist to ensure an airtight seal.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518913863853,"sku":"330101-00-25-20-12-05","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-330101-00-25-20-12-05-probes-jc2atv3xrbs.jpg?v=1766981511","url":"https:\/\/www.maxwellplc.com\/products\/bently-nevada-330101-00-25-20-12-05-3300-xl-8mm-proximity-probe","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
