        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • No Onboard Firmware: The Bently Nevada 21000-16-05-00-033-04-02 is a purely passive mechanical assembly. It contains no electronics, memory, or firmware. Therefore, it never requires firmware updates, patching, or configuration via software.
        • System-Level Updates Apply to Monitoring Rack: Although the housing itself has no firmware, the overall monitoring performance can be enhanced by updating the firmware in the connected Bently Nevada monitoring system (e.g., a 3500 rack) or the proximitor’s signal conditioning algorithms.
        • Probe Calibration Remains Stable: The 3300 XL probe’s sensitivity and linearity are factory-calibrated and fixed. No field updates or recalibration are needed under normal conditions, simplifying long-term maintenance and reliability.
        • Obsolescence Management: As a mechanical housing with a proven probe technology, this assembly is field-replaceable and backward-compatible. Future updates from Bently Nevada would involve new probe or housing versions (e.g., 3300 XL vs. 3300 NSv), not firmware patches, ensuring a stable supply chain for critical spares.
        • Direct Conduit Connection: The 3/4-14 NPT fitting option (E:04) with a single plug provides a simple, sealed entry point for rigid or flexible metallic conduit, protecting the probe cable from mechanical damage and oil contamination.
        • Standard Coaxial Extension Interface: The 3300 XL 8mm probe terminates in a miniature coaxial ClickLoc connector, allowing it to connect seamlessly to standard Bently Nevada extension cables (such as 3300 XL 8mm extension cables) and then to a proximitor.
        • Passive Analog Signal Chain: This housing contains no active electronics; it mechanically positions the probe. The resulting eddy current signal is a high-frequency analog voltage change (gap voltage), which is transmitted via coaxial cable to a remotely mounted proximitor for demodulation into a DC signal proportional to position.
        • API 670 Compliant Mounting: The mechanical interface (mounting thread and housing dimensions) is fully compliant with API 670 requirements for externally mounted proximity probe housings, ensuring interoperability with standard machine case mounting pads and retrofit scenarios.
        • Continuous Shaft Vibration Monitoring: Ideal for non-contact radial vibration measurement on high-speed rotating machinery such as centrifugal and axial compressors, helping detect unbalance, misalignment, and bearing wear.
        • Axial Thrust Position Measurement: Used on steam and gas turbines to monitor rotor axial displacement, preventing catastrophic thrust bearing failure and rotor-stator rub.
        • Shaft Eccentricity & Differential Expansion: Essential during turbine startup and shutdown to measure bowing of the rotor or differential thermal growth between rotor and casing, avoiding costly contact damage.
        • General-Purpose Machinery Protection: Cost-effective solution for monitoring pumps, fans, and blowers in non-hazardous industrial environments where performance and API standards are required but explosion-proofing is not.

        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
        In which specific applications should I use the Bently Nevada 21000-16-05-00-033-04-02?
        This assembly is best suited for non-hazardous, general-purpose areas where external mounting of a proximity probe is required for continuous shaft monitoring. Common applications include radial vibration monitoring on centrifugal compressors, axial thrust position measurement on steam turbines, shaft eccentricity monitoring on gas turbines during startup, and differential expansion measurements on large industrial fans or pumps where API 670 compliance is desired but explosion-proof ratings are not mandated.
        What happens if the ambient temperature around the Bently Nevada 21000-16-05-00-033-04-02 drops below -34°C (-30°F)?
        According to Bently Nevada's technical datasheet, exposing the 3300 XL probe inside this assembly to temperatures below -34°C can cause the internal pressure seal to fail prematurely. This could lead to loss of probe gap voltage, erratic readings, or complete sensor failure. If your installation site experiences such low temperatures, you must either provide local heating or select a different probe type specifically rated for cryogenic service.
        Doesthe Bently Nevada 21000-16-05-00-033-04-02require any additional support for the probe sleeve during operation?
        No. For this specific configuration (standoff adapter C=00 and probe penetration D=033 = 3.3 inches), the total exposed sleeve length is only 3.3 inches (83.8 mm). Bently Nevada specifies that additional sleeve support (e.g., part number 37948-01) is required only when the total penetration length (C + D) exceeds 12 inches (304 mm). This assembly is well within the safe, unsupported limit.
        Can I use the Bently Nevada 21000-16-05-00-033-04-02 in a Div 1 hazardous area?
        No. This standard 21000 model (non-CA version) is not certified as explosion-proof. For Class I, Division 1 or 2 hazardous locations requiring CSA explosion-proof ratings, you would need to order the CA21000 version of the housing. This standard assembly is intended for general-purpose (safe area) use or installations where the housing itself is located in a non-hazardous environment.
        Is the Bently Nevada 21000-16-05-00-033-04-02 compatible with older Bently Nevada monitoring systems?
        Yes, the 3300 XL 8mm probe used in this assembly is backward-compatible with many older 3300 and 7200 series proximity monitoring systems, provided the correct extension cable and proximitor are used. However, for full API 670 compliance and best performance, pairing it with a modern 3500 monitoring system or a compatible rack such as the Trendmaster or 1900 series is recommended. Always verify system impedance matching (typically 10 m coaxial cable).
