The 8 mm PPS tip generates an RF field to achieve eddy-current probe scaling over a 2.0 mm linear range. Operational accuracy depends on gap voltage validation during local mechanical installation. Field personnel must adjust the threaded mounting sleeve depth until the static output across the matching Proximitor reads the defined -10 VDC targets. This alignment registers the target surface inside the optimal sector of the scale factor loop, ensuring precise capture of rotor dynamics while maintaining cross-talk suppression against adjacent radial or axial transducers inside the same bearing housing.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the short 0.5 metre total probe length affect matching extension cables and Proximitor tuning?\u003c\/p\u003e\n\u003cp\u003eA: The proximity transducer system requires a fixed electrical length of either 5.0 metres or 9.0 metres. A 0.5 metre probe must be paired exclusively with a matching extension cable (such as a 4.5 metre or 8.5 metre model) to satisfy total network impedance and prevent errors in eddy-current probe scaling.\u003c\/p\u003e\n\u003cp\u003eQ: What are the consequences of letting fluid contaminants access the ClickLoc coaxial connector?\u003c\/p\u003e\n\u003cp\u003eA: Moisture or oil ingress at the coaxial junction degrades the insulation resistance of the 75 Ohm line. This causes drift during gap voltage validation and distorts higher frequency components critical for assessing complex rotor dynamics.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eReverse Housing Mechanical Fit\u003c\/strong\u003e: Install the probe through the rear entry bore or housing block. Thread the casing into position by hand to prevent thread binding on the AISI 303\/304 stainless steel barrel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStatic Gap Verification\u003c\/strong\u003e: Connect the 0.5 metre lead to the matched extension cable linked to an active Proximitor Sensor.

Keep the voltmeter monitored during this step to verify that the tightening torque does not shift the probe head away from its target baseline.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoaxial Routing and Ground Isolation\u003c\/strong\u003e: Route the flexible lead through oil-resistant conduit. Ensure the cable maintains a static bend radius greater than 25.4 mm, and secure the ClickLoc connection within an insulated terminal box to prevent grounding against the machine frame.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":43605144207450,"sku":"330105-02-12-05-02-00","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/330101-00-16-10-02-00_b3c892a2-e7de-4a84-8d2f-83fcea898aa8.png?v=1783326292","url":"https:\/\/www.spareoil.com\/es\/products\/bently-nevada-330105-02-12-05-02-00-3300-xl-series-proximity-sensors","provider":"SpareOil Automation","version":"1.0","type":"link"}
