        • IP66 / NEMA Type 4X Environmental Protection – High-strength PPS housing ensures dependable, sealed operation in outdoor, high-humidity, and salt-laden atmospheres typical of offshore platforms and coastal refineries.
        • SIL System Capability – When integrated into a properly configured, redundant Bently Nevada monitoring framework (such as a 2oo3 voting architecture), the transducer loop supports safety instrumented functions (SIF) up to SIL 2/3 compliance per IEC 61508.
        • Centrifugal & Axial Compressors – Installed directly into the machine casing to monitor radial shaft vibration and axial thrust position in hydrocarbon processing and gas transmission.
        • Steam & Gas Turbines – Used for differential expansion and case expansion monitoring, protecting blade tip clearances and rotor positioning during startup and load changes.
        • Large Industrial Pumps & Fans – Provides early warning of unbalance, misalignment, and bearing wear in critical service pumps, including boiler feed, pipeline, and cooling water pumps.
        • Hydroelectric & Wind Turbine Gearboxes – Suitable for low-speed shaft runout measurement and high-speed shaft proximity monitoring where contact sensors are not feasible.
        Description
        The Bently Nevada 330881-28-00-061-03-02 represents an advanced evolution in proximity monitoring. Unlike traditional probe systems that require separate probes, extension cables, and Proximitor sensors, this PROXPAC XL assembly combines the 3300 XL 8mm eddy current probe and its signal conditioner into one rugged, injection-molded Polyphenylene Sulfide (PPS) housing. This integration significantly reduces installation complexity and potential failure points, making the Bently Nevada 330881-28-00-061-03-02 ideal for new builds and retrofits on compressors, turbines, and pumps.

        Engineered for severe service environments, the Bently Nevada 330881-28-00-061-03-02 carries a Type 4X and IP66 rating, ensuring protection against hose-directed water, dust, and corrosive atmospheres. The housing incorporates conductive fibers for effective electrostatic charge dissipation. Featuring a 61mm probe penetration (C dimension), a 3/4-14 NPT conduit fitting option with an included 1/2-14 NPT reducer (D option), and a 3/4-14 NPT mounting thread, this specific Bently Nevada 330881-28-00-061-03-02 model provides flexible, secure installation directly into machine casings.

        Performance-wise, the Bently Nevada 330881-28-00-061-03-02 delivers a 2mm linear range (0.25mm to 2.3mm) with a standard scale factor of 7.87 V/mm (200 mV/mil). It supports field wiring lengths up to 305 meters without signal degradation below 10 kHz. The system operates with a probe tip rated from -51°C to +177°C and an electronics section from -51°C to +100°C. By integrating multiple hazardous area approvals (ATEX, IECEx, CSA), the Bently Nevada 330881-28-00-061-03-02 safely operates in Zone 0, Zone 1, and Division 1 classified locations.

        Technical notes
        Bently Nevada 330881-28-00-061-03-02 requires a stable -17.5 Vdc to -26 Vdc power supply for proper linear range operation; operation above -23.5 Vdc may reduce the 2mm linear range. Users should ensure that the 61mm probe penetration length (C dimension) and the 3/4-14 NPT mounting thread are compatible with the machine casing thickness to avoid side-view effects.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        What types of machinery is the Bently Nevada 330881-28-00-061-03-02 typically installed on?
        This transducer is designed for critical rotating machinery in hydrocarbon and power generation industries, including centrifugal and axial compressors, steam turbines, gas turbines, expanders, and large pumps. It measures radial vibration, axial (thrust) position, and differential expansion.
        Can the Bently Nevada 330881-28-00-061-03-02 be used in a safety instrumented system (SIS)?
        Yes. The 3300 XL technology is widely accepted for machine protection systems (overspeed, vibration trip). However, always verify the complete loop (transducer + monitor) complies with your required SIL level per IEC 61508 using official Bently Nevada safety manuals.
        What happens if the probe tip of Bently Nevada 330881-28-00-061-03-02 accidentally comes into contact with high-pressure steam or hot water?
        The PPS housing and probe tip are rated for brief contact (up to one week) with hot water at 95°C (203°F) and condensing steam without significant strength loss. However, prolonged exposure (6-8 weeks) may reduce housing strength to approximately 50% of initial value. Bently Nevada does not guarantee the pressure seal for all applications.
