To maintain measurement linearity, system calibration relies on a baseline target of AISI 4140 steel. During static commissioning, gap voltage validation (-10 VDC targets) must be verified using a digital multimeter at the Proximitor output terminal. This negative DC voltage corresponds to the physical center of the linear range. Proper spatial separation between adjacent 11 mm tips must be maintained to achieve cross-talk suppression, preventing mutual electromagnetic interference from corrupting the dynamic vibration waveform.\u003c\/p\u003e\n\u003ch3\u003eKit Composition\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Bently Nevada 330703-000-100-10-11-00 11 mm Proximity Probe\u003c\/li\u003e\n\u003cli\u003e1 x Integrated FluidLoc coaxial connector with factory-fitted connector protector\u003c\/li\u003e\n\u003cli\u003e2 x Hexagonal mounting nuts (3\/8-24 thread)\u003c\/li\u003e\n\u003cli\u003e1 x Technical installation leaflet containing material certification data\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMechanical Mounting \u0026amp; Cable Routing\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMaintain a minimum target material width of three times the probe tip diameter (33 mm) to ensure full eddy-current field development.\u003c\/li\u003e\n\u003cli\u003eIsolate the coaxial extension cable from structural components using non-conductive conduit to prevent capacitive grounding paths.\u003c\/li\u003e\n\u003cli\u003eTorque the case locknuts to a maximum limit of 11.2 N-m (100 in-lb) into the housing structure to prevent mechanical deformation of the probe barrel.\u003c\/li\u003e\n\u003cli\u003eAvoid sharp bends in the coaxial lead; ensure the minimum bend radius does not drop below 25.4 mm (1.0 in).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eLogistics \u0026amp; Handling Protocol\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDispatch timeframe: 2-7 days when payment finish.\u003c\/li\u003e\n\u003cli\u003eConsignment shipped globally via premium couriers including DHL, FEDEX, or UPS.\u003c\/li\u003e\n\u003cli\u003eAll items are enclosed within anti-static industrial packaging to negate static discharge risks and withstand heavy shock impacts during transit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eStructural Performance FAQ\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eWhat limits the hot-swap capability of this hardware component within an active TSI loop?\u003c\/p\u003e\n\u003cp\u003eThe probe itself is a passive sensor and contains no active electronic components, allowing physical replacement without turning off the system. However, disconnecting the probe alters the total impedance of the transducer circuit, which immediately triggers a NOT OK fault condition on the associated 3500 monitor channel.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the external backplane current consumption profile for this specific probe?\u003c\/p\u003e\n\u003cp\u003eThe hardware consumes zero current directly from any processing backplane because it functions as a passive inductive load. All operational excitation current and high-frequency RF signals are supplied to the probe via the external 3300 XL Proximitor Sensor, which regulates the power envelope.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow does mismatching cable lengths affect the system calibration scale factor?\u003c\/p\u003e\n\u003cp\u003eThe total electrical length of the system must equal exactly 5.0 m or 9.0 m based on the Proximitor calibration. Connecting a 1.0 m probe directly to a Proximitor designed for a 9.0 m system without the correct extension cable shifts the resonance frequency and alters the 3.94 V\/mm scale factor.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the signal transmission latency over the maximum allowed cable distance?\u003c\/p\u003e\n\u003cp\u003eThe transmission latency through the coaxial media is negligible, operating at a fraction of a microsecond across the total physical length of the extension cable. The phase shift induced by the physical cable line does not impact standard rotor vibration analysis within normal operational frequencies.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow is electrical isolation maintained between the probe case and internal signaling?\u003c\/p\u003e\n\u003cp\u003eThe coaxial signal lines are physically and electrically isolated from the external stainless steel probe case. The internal structure uses high-temperature material layers to ensure the insulation resistance between the outer shield of the connector and the threaded case exceeds 500 megohms at 500 VDC.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat are the firmware flash compatibility requirements for this proximity probe?\u003c\/p\u003e\n\u003cp\u003eThis hardware is a purely analog physical sensor and does not contain any firmware, microprocessors, or digital logic arrays. It requires no software configuration or flashing, ensuring total backwards compatibility across all legacy and current generations of analog Bently Nevada monitors.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eHow does temperature variance impact the linear measurement accuracy of the tip?\u003c\/p\u003e\n\u003cp\u003eTemperature changes cause slight thermal expansion in the coil and case, altering system impedance. The 3300 XL 11 mm design compensates for this across its operational range, keeping the total thermal scale factor error under plus or minus 15 percent over the entire temperature spectrum.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eWhat is the maximum pressure limit for the FluidLoc connector interface?\u003c\/p\u003e\n\u003cp\u003eThe FluidLoc coaxial connector option features an internal seal designed to block moisture and oil migration along the cable core. It prevents process fluids from leaking through the cable under low-pressure exposures, but it must not be used as a primary high-pressure process seal.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518845771949,"sku":"330703-000-100-10-11-00","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-330703-000-100-10-11-00-3300-xl-11-mm-proximity-probes-4pbevj3yrvm.jpg?v=1766980296","url":"https:\/\/www.maxwellplc.com\/products\/330703-000-100-10-11-00-bently-nevada-3300-xl-11-mm-proximity-probes","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
