This heavy-duty eddy current sensor provides an extended linear measurement window compared to standard 8mm variants, making it the industry benchmark for monitoring substantial axial thrust movement, thermal shaft growth, and radial vibration parameters on large rotating components.\u003c\/p\u003e\n\u003cp\u003eReliability engineers deploy this 11mm probe system inside comprehensive Turbine Supervisory Instrumentation (TSI) layouts to protect high-capital utility assets, including massive steam and gas utility turbines, large scale process compressors, and heavy industrial generators. The internal coil structure delivers an ultra-stable analog raw waveform that resists cross-talk and side-viewing interference. This premium data streams directly to centralized monitoring backplanes and automated emergency shutdown circuits, driving split-second interlocks to trip operations instantly before catastrophic shaft movement destroys the main bearing assemblies.\u003c\/p\u003e\n\u003ch2\u003eStructural Suffix Blueprint Decoding\u003c\/h2\u003e\n\u003ch3\u003e330704 [3300 XL 11 mm Probe with 1\/2-20 UNF Imperial Thread]\u003c\/h3\u003e\n\u003cp\u003eIdentifies the core hardware block as an extended-range 11 mm tip diameter proximity probe utilizing standard 1\/2-20 UNF external casing threads for rugged mechanical installation.\u003c\/p\u003e\n\u003ch3\u003e-000 [Unthreaded Length Metric]\u003c\/h3\u003e\n\u003cp\u003eSpecifies a 0.0-inch unthreaded barrel profile, indicating that mounting threads cover the entire length of the stainless steel sleeve to deliver maximum depth positioning adjustments during field installation.\u003c\/p\u003e\n\u003ch3\u003e-040 [Overall Case Length Metric]\u003c\/h3\u003e\n\u003cp\u003eEstablishes the total threaded case length as 4.0 inches, providing the deep structural reach required to span heavy machinery housings or external bearing caps.\u003c\/p\u003e\n\u003ch3\u003e-10 [Total Integrated Cable Length]\u003c\/h3\u003e\n\u003cp\u003eDefines a 1.0-meter (3.3 feet) integrated coaxial lead line, measured precisely from the molded sensor head tip to the male miniature connection terminal.\u003c\/p\u003e\n\u003ch3\u003e-02 [Stainless Steel Armor Shielding]\u003c\/h3\u003e\n\u003cp\u003eEquips the integrated coaxial line with a flexible, fluid-tight stainless steel armor jacket over its entire physical length to shield the underlying dielectric layers from physical crushing, hot oil, or severe mechanical abrasion.\u003c\/p\u003e\n\u003ch3\u003e-05 [Global Safety Framework Authorization]\u003c\/h3\u003e\n\u003cp\u003eCarries comprehensive multi-agency international hazardous area certifications, including ATEX, IECEx, and North American safety standards, enabling continuous secure operation within intrinsically safe zones.\u003c\/p\u003e\n\u003ch2\u003eMechanical \u0026amp;

Geometric Alignment Manual\u003c\/h2\u003e\n\u003cp\u003eField instrumentation crews must establish the precise mechanical gap clearance using an accurate digital voltmeter during physical deployment. Due to the extended 4.0 mm linear tracking window of the 11mm sensor system, the calibrated midpoint voltage differs significantly from standard 8mm loops. Thread the probe into the machine casing port while monitoring the raw DC gap voltage at the remote 3300 XL 11mm Proximitor sensor test points. Adjust the probe depth until the meter displays approximately -10.0 VDC, securing the sensor face exactly at the mathematical center of the calibrated tracking band.\u003c\/p\u003e\n\u003cp\u003eMaintain a strict minimum bend radius of 25.4 mm (1.0 inch) along the armored coaxial line to prevent internal core kinking or structural signal attenuation. Route the armored line through dedicated, grounded instrument raceways to isolate the low-voltage analog signal from nearby high-voltage lines. Technicians must verify that the selected extension cable pairs correctly with this 1.0-meter probe to match the exact 5.0-meter or 9.0-meter total electrical loop length required by the remote Proximitor module.\u003c\/p\u003e\n\u003ch2\u003eMaterial Resilience \u0026amp; Distributed Automation Bridging\u003c\/h2\u003e\n\u003cp\u003eThe advanced engineering of the 3300 XL 11mm probe utilizes a specialized high-performance composite tip material, injection-molded over the internal wire coil to create an airtight seal.

Spreading the electrical modulation over double the physical distance naturally scales down the incremental sensitivity to 3.94 V\/mm (100 mV\/mil) to keep the final analog voltage output within standard industrial ranges.\u003c\/p\u003e\n\u003ch3\u003eQ2: Can I connect this 3300 XL 11mm probe directly to a standard 3300 XL 8mm Proximitor sensor?\u003c\/h3\u003e\n\u003cp\u003eA2: No. The internal electrical properties and target calibrations differ completely between 8mm and 11mm systems. Mixing an 11mm probe head with an 8mm Proximitor creates a major impedance mismatch, which de-calibrates the transducer path and yields completely invalid displacement telemetry. You must pair this probe with a dedicated 3300 XL 11mm Proximitor sensor module.\u003c\/p\u003e\n\u003ch3\u003eQ3: What installation issue does the -02 stainless steel armor option solve over unarmored lines?\u003c\/h3\u003e\n\u003cp\u003eA3: The -02 stainless steel armor option provides a rugged physical defense system that protects the coaxial core from getting pinched, cut, or crushed along exposed machinery runs. It eliminates the risk of signal drops or open-circuit faults caused by physical impacts or high-pressure spray washes during routine plant maintenance.\u003c\/p\u003e\n\u003ch3\u003eQ4: What action should I take if the monitoring loop reads a constant 0 VDC terminal voltage?\u003c\/h3\u003e\n\u003cp\u003eA4: A 0 VDC output from the proximity loop indicates a short circuit to ground. Inspect the armored coaxial line along its run for physical pinholes or internal pinches where the inner conductor might touch the outer shield. Check inside the ClickLoc connector for fluid or metal dust ingress, and dry or clean the terminal faces to restore the proper isolation barrier.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45518883946669,"sku":"330704-000-040-10-02-05","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/bently-nevada-330704-000-040-10-02-05-3300-xl-11-mm-proximity-probes-t2ty3wm3flm.jpg?v=1766980990","url":"https:\/\/www.maxwellplc.com\/products\/bently-nevada-330704-000-040-10-02-05-3300-xl-11mm-proximity-displacement-probe","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
