The 21000, 24701, and 164818 Proximity Probe Housing Assemblies are available with Canadian Standards Association (CSA) approvals. They are rated explosion proof for hazardous areas. You can order hazardous area approved proximity probes with 21000 aluminum and 24701 stainless steel housings for intrinsically safe applications. Both housings are certified as CSA Type 4 enclosures and are fully compliant with the American Petroleum Institute's (API) 670 Standard for externally mounted proximity probe housings.

When using the 24701-34-05-00-043-03-02 aluminum housing assembly, the primary considerations are the safety of online adjustment and the integrity of the sealing system. First, given its 4.3-inch (109mm) penetration depth, it is crucial to accurately verify the bearing housing wall thickness before installation to prevent physical collision between the probe tip and the rotating shaft. When fine-tuning the gap during operation, monitor the bias voltage in real-time to lock it at the -10VDC linear center. Second, periodically inspect the elasticity and condition of the Viton O-rings to prevent lubricating oil leakage or the ingress of external moisture.Additionally, as this model features a 0.5-meter short cable, it must be paired with a correctly lengthened 3300 XL extension cable to meet the Proximitor's requirements.Finally, when used in hazardous areas, strict adherence to explosion-proof wiring and shielding/grounding protocols corresponding to its -34 multiple approvals is mandatory to ensure signal transmission remains undisturbed by on-site electromagnetic interference (EMI).
It is a Bently Nevada 24701 series aluminum proximity probe housing assembly.
How to use products like the 24701-34-05-00-043-03-02?
It is installed onto the bearing housing via the 3/4-14 NPT thread. Technicians can precisely set the gap voltage (typically -10VDC) between the probe and the shaft externally using the adjustment mechanism without disassembling the machine.
What are the main advantages of the 24701-34-05-00-043-03-02?
The core advantage is online maintainability. It complies with the API 670 standard, allowing for probe replacement or gap adjustment while the unit is running. The aluminum housing also effectively resists harsh outdoor weather.
Does the 24701-34-05-00-043-03-02 include a Proximitor?
No, it does not. It only includes the housing and the internal probe. You must separately configure a 3300 XL Proximitor and a 3300 XL extension cable with a matching total system length.
Can the 24701-34-05-00-043-03-02 be used in hazardous areas?
Yes. The -34 option indicates that the built-in probe carries multiple international agency approvals (such as CSA, ATEX, IECEx). It is suitable for explosive environments when used with the correct safety barriers.
