  • 21000 and 24701 Proximity Probe Housing Assemblies
The 21000 and 24701 Proximity Probe Housing Assemblies are available with Canadian Standards Association (CSA) approvals. They are rated explosion proof for hazardous areas. Bently Nevada offers a probe support and oil seal (part number 37948-01) for long sleeves that must go through an inner bearing housing.

To externally mount proximity probes, use one of these allmetal Proximity Probe Housing Assemblies: 21000 aluminum probe housing assembly; 24701 stainless steel probe housing assembly The 21000 and 24701 Proximity Probe Housing Assemblies consist of the following parts:A dome cover that screws into the body of the housing; Threaded ports for conduit connections; A probe sleeve of optional length; 0-rings; A reverse mount proximity probe; A thread seal; Optional conduit fittings; An optional standoff adapter.

The 24701-28-05-65-105-03-02 Bently Nevada Proximity Probe Housing Assemblies may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Eddy current proximity sensor or system component, commonly used in the monitoring of industrial rotating machinery. Its working principle is based on high-frequency electromagnetic field coupling and the eddy current effect, and it is mainly used for non-contact measurement of shaft vibration, displacement, or axial motion.
1. Compliance: Fully compliant with American Petroleum Institute (API) 670 standard, suitable for external proximity probe housings.
2. Materials: Constructed with a 303 stainless steel body and a 304 stainless steel sheath, ensuring high durability in corrosive environments.
3. Protection Rating: Meets CSA Type 4 protection standards; suitable for explosion-proof applications if relevant certifications are required at the time of ordering.

Ask our team:

  • In which specific high-speed fluid environments is the 24701-28-05-65-105-03-02 designed to maintain structural and signal stability?
    The 24701-28-05-65-105-03-02 is designed for environments with steam or extreme temperature differences, such as steam turbines and high-temperature gas turbines. Due to its special ceramic cap tip and gold-plated internal components, the 24701-28-05-65-105-03-02 maintains a tight seal even when standard probes are susceptible to moisture or thermal expansion.
  • How does the "28-05" configuration in the name 24701-28-05-65-105-03-02 reflect its mechanical structure?
    The numerical combination in 24701-28-05-65-105-03-02 represents the precise physical dimensions required for embedded installation. Specifically, "28" indicates an untapping length of 2.8 inches, and "05" indicates a total housing length of 5.0 inches. This ensures that the 24701-28-05-65-105-03-02 can pass through the heavy mechanical housing to reach the target axis without mechanical interference.
  • How does the 24701-28-05-65-105-03-02 mitigate the impact of extreme thermal cycling on eddy current linearity?
    The 24701-28-05-65-105-03-02 employs an advanced temperature-compensated coil. Because the resistance of the probe coil changes with temperature, the 24701-28-05-65-105-03-02 is calibrated for use with the 3300 XL proximity sensor to ensure that the average scaling factor (ASF) remains within tight tolerances even when the probe tip temperature reaches 260°C (500°F).
  • How much dielectric strength does the FEP outer sheath of the 24701-28-05-65-105-03-02 provide in a chemically corrosive sump?
    The fluorinated ethylene propylene (FEP) cable used in the 24701-28-05-65-105-03-02 exhibits excellent resistance to corrosive lubricants and chemical solvents. This ensures that insulation breakdown will not occur in the 24701-28-05-65-105-03-02, which would otherwise lead to grounding loops or signal attenuation in the vibration monitoring circuitry.
  • Why is the 24701-28-05-65-105-03-02 critical for mechanical protection systems compliant with API 670 standards?
    As an 8mm probe system, the 24701-28-05-65-105-03-02 provides a standardized 200 mV/mil (7.87 V/mm) output required for industry-standard vibration monitoring. The 24701-28-05-65-105-03-02 facilitates high-fidelity data acquisition, enabling the detection of the “phase” and “track” characteristics of rotating shafts, which is crucial for meeting the safety requirements of the American Petroleum Institute (API).
