      Information

      Overview Manuals Application suggestions Core functionality
      The Bently Nevada 21000-16-10-00-046-04-02 belongs to the 21000 series aluminum eddy current probe protective cover assembly. It is an external installation solution designed specifically for industrial rotating machinery such as turbines, compressors, pumps, and fans, compliant with API 670 standards, used to protect and accommodate eddy current probes for monitoring shaft vibration, shaft displacement, or speed.
        • Aluminum construction
        • Explosion-proof and CSA Type 4 rated
        • Compliant with API 670
      The 21000, 24701, and 164818 Proximity Probe HousingAssemblies are available with Canadian StandardsAssociation (CSA) approvals. They are rated explosion prooffor hazardous areas.

      Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. 
      Bently Nevada 21000-16-10-00-046-04-02 Proximity Probe Housing Assemblies Manuals, Datasheets, Drivers, Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description.
      Maintenance convenience: This component utilizes an external dome cover design, and technicians only need to unscrew the top cover to access the probe and extension cable, greatly simplifying the gap adjustment process. Spare parts selection: If your application environment does not require explosion-proof, manufacturers usually recommend using the updated 31000/32000 series, which has more flexible installation methods and better environmental resistance.Sealing inspection: Early failure of the probe pressure seal may occur at extreme low temperatures below -34 ° C, and attention should be paid to environmental temperature monitoring.
      This component enables external installation and online adjustability, allowing technicians to calibrate or replace probes without shutting down equipment, significantly reducing downtime. Its aluminum housing provides CSA Type 4 protection against dust, moisture, oil, and corrosive gases, while the stainless steel sleeve ensures mechanical isolation from physical damage. The unit features a reliable pressure-sealing structure to prevent leakage and meets explosion-proof standards for hazardous environments. Additionally, the metal enclosure offers EMI shielding and stable threaded mounting, ensuring accurate and reliable signal transmission in industrial vibration monitoring applications.

      FAQ View All FAQ

      • What is 21000-16-10-00-046-04-02?
        21000-16-10-00-046-04-02 is a Proximity Probe Housing Assembly
      • Can the internal probe be replaced separately if the 21000-16-10-00-046-04-02 probe is damaged?
        Okay. The original design intention of this component is to facilitate replacement. According to the model number -16-10, you need to order a 3300 XL 8mm probe with a cable length of 1.0 meter. When replacing, simply unscrew the top cover of the protective cover without disassembling the entire protective cover body or stopping the machine.
      • What does the length of 21000-16-10-00-046-04-02
        It refers to the probe penetration length. It refers to the distance from the sealing surface of the protective cover installation thread (3/4-14 NPT) to the probe tip. During installation, it is necessary to ensure that this length allows the probe to accurately align with the surface of the measured axis.
      • Does this 21000-16-10-00-046-04-02 model come with explosion-proof certification?
        Without it. The -16 option in the model represents a standard probe and does not have multiple approvals. If your site belongs to a hazardous area (such as a chemical plant, oil and gas zone), you usually need to choose -26 (3300 XL 8mm probe with multiple certifications) or other explosion-proof options.
      • Can this 21000-16-10-00-046-04-02 model be used in high-temperature environments?
        Okay. The working temperature range of this aluminum casing is typically -51 ° C to+177 ° C (-60 ° F to+350 ° F). However, it should be noted that if there are highly corrosive gases on site, it is usually recommended to choose the 24701 series (stainless steel material) instead
      • What is the difference between this aluminum shell (21000) and stainless steel shell (24701)?
        21000 series: Made of aluminum body, lightweight (about 1.1kg), cost-effective, suitable for most standard industrial environments (such as electricity, water treatment). 24701 series: Made of stainless steel body, highly corrosion-resistant. If your device is in a highly corrosive environment (such as offshore platforms, chemical plants with high acidity or alkalinity), it is recommended to replace the 21000 with the 24701 series.
      • What does the 21000-16-10-00-046-04-02
        There are multiple outlet holes on the protective cover body. -04 means that the manufacturer will provide you with a 3/4-14 NPT metal plug at the factory to block unused outlet holes, ensuring a protection level (usually IP66 or higher). If you need to connect a conduit, you usually remove this plug.
