Bently Nevada 24701-28-05-00-070-00-02 Proximity Probe Housing Assembly
Product Overview and Core Function
This official Bently Nevada 24701-28-05-00-070-00-02 provides a complete housing solution for proximity probes. As a result, it effectively protects the probe in harsh industrial environments. The device belongs to the 24701 Series for turbomachinery monitoring applications. Specifically, this assembly includes a 3300 XL 8mm probe with approval options. Consequently, you get reliable shaft vibration and position measurement in one robust package.

Key Technical Parameters and Configuration
The Bently Nevada 24701-28-05-00-070-00-02 features a 303 stainless steel body with a 304 stainless steel sleeve. For instance, the probe cable length is 0.5 metre (20 inches). The probe penetration measures 0.7 inches (070 code) with no standoff adapter. The maximum (C) + (D) dimension with visible probe is not applicable for this model. Similarly, the maximum total (C) + (D) dimension reaches 13.5 inches (34.3 mm).

Materials and Mechanical Construction
The housing body uses 303 stainless steel for excellent corrosion resistance. Its sleeve features 304 stainless steel for additional durability. In addition, the assembly includes a dome cover that screws into the housing body. Threaded ports allow for easy conduit connections. Specifically, the probe sleeve comes in an optional length as configured. O-rings and a thread seal provide proper environmental protection accordingly.

Fittings and Mounting Specifications
This model includes no fittings with Option 00. For example, you get no NPT plugs, no reducers, and no cable seal grips. Therefore, users must supply all necessary conduit fittings separately. The mounting thread is 3/4-14 NPT (Option 02). Consequently, this thread matches standard industrial conduit fittings perfectly. As a result, you have complete flexibility to choose your own cable sealing solution.

Physical and Environmental Ratings
The typical weight is 1.8 kg (4.1 lb) without fittings. The probe operates reliably in demanding conditions. Housing materials resist UV damage and provide mechanical strength. Specifically, the 303 and 304 stainless steel construction offers excellent durability. As a result, this assembly withstands vibration and harsh industrial environments.

Component Breakdown: Housing and Sealing Parts
The Bently Nevada 24701-28-05-00-070-00-02 assembly consists of several key parts. For instance, a dome cover screws directly into the housing body. Consequently, this cover provides easy access for probe installation. Threaded ports provide conduit connection points for field wiring. A probe sleeve of optional length holds the probe securely in position. Similarly, O-rings and a thread seal prevent contamination and moisture ingress.

Component Breakdown: Probe and Fittings
A reverse mount proximity probe is included as part of this assembly. Therefore, you do not need to purchase a separate probe. This model includes an approved 3300 XL 8mm probe with certification. Optional conduit fittings are not included in this specific configuration. Similarly, an optional standoff adapter is not provided with model 24701-28-05-00-070-00-02. The fittings option is set to 00, meaning no fittings come with the housing.

Installation Guide
Mount the housing using the 3/4-14 NPT mounting thread. First, install the probe sleeve at the desired length. Next, insert the 3300 XL 8mm approved probe into the sleeve. Use the provided O-rings and thread seal to prevent leakage. Then, connect your own conduit and fittings to the threaded ports. Install appropriate cable seals for your field wiring. Finally, screw the dome cover onto the housing body. Always verify that the probe does not contact rotating machinery.
