Bently Nevada 24701-34-05-00-031-04-02 Proximity Probe Housing Assembly

Product Introduction

The Bently Nevada 24701-34-05-00-031-04-02 arrives as a factory-assembled unit that protects and houses a reverse-mount proximity probe. This assembly simplifies installation and maintenance for critical turbomachinery. Specifically, this model supports the 3300 XL 8 mm probe system. The housing features a 303 stainless steel body with a 304 stainless steel sleeve, which ensures excellent corrosion resistance. Additionally, selectable hazardous area approvals make this unit versatile for various plant environments.

Technical Specifications

The 24701 series offers many configurable options to address specific application needs. Suffix code 34 identifies the probe option for this particular model. Specifically, it specifies a 3300 XL 8 mm probe that comes with a connector protector. Furthermore, this code includes hazardous area approvals for enhanced safety compliance.

The probe cable length uses suffix code 05, which indicates a 0.5-meter (20-inch) cable. This compact length works ideally for installations where the signal conditioner sits close to the probe. Code 00 shows the absence of a standoff adapter, which provides a direct mounting solution.

For the 24701-34-05-00-031-04-02, code 031 sets the probe penetration depth at 3.1 inches. This precise dimension plays a crucial role in correct probe positioning. Code 04 denotes the fittings option, which includes one 3/4-14 NPT plug. Moreover, code 02 indicates the mounting thread option, also featuring a 3/4-14 NPT thread standard. The maximum combined dimension (C) + (D) for this assembly measures 13.5 inches (34.3 cm).

Mechanical and Environmental Features

The housing construction uses a robust 303 stainless steel body combined with a 304 stainless steel sleeve. This material choice provides high strength and resistance to oxidation. Therefore, this Bently Nevada 24701 housing performs well in harsh industrial conditions. Without fittings, the assembly typically weighs about 1.8 kg (4.1 lb). With packaging, the gross weight reaches approximately 2.22 kg.

This design incorporates several key components. A dome cover screws securely into the body. Threaded ports facilitate conduit connections. Additionally, the assembly includes a probe sleeve of the specified length, O-rings, and a thread seal. An optional standoff adapter remains available, though this configuration does not include it.

Installation Guidelines

Installing the 24701-34-05-00-031-04-02 requires careful attention to the specified dimensions. First, clean the mounting surface and properly prepare the 3/4-14 NPT threaded hole. Use the included NPT plug to seal any unused ports. This practice helps maintain the housing's environmental integrity.

Next, insert the probe to achieve the correct penetration depth. The 3.1 in setting comes factory-specified for this model. The total distance from the mounting surface to the probe tip significantly affects measurement accuracy. Remember, the maximum (C)+(D) dimension measures 13.5 inches. Always verify this measurement during installation to avoid probe damage. For specific wiring, consult the manual regarding hazardous area compliance where applicable.
