Bently Nevada 24701-28-05-00-090-04-02 Proximity Probe Housing Assembly

Product Introduction

The Bently Nevada 24701-28-05-00-090-04-02 is a complete Proximity Probe Housing Assembly. It holds and protects a proximity probe in harsh machine environments. This model uses a 3300 XL 8mm probe with multiple agency approvals.

Additionally, the assembly features a 0.5 metre probe cable and 9-inch probe penetration. The 3/4-14 NPT mounting thread matches standard conduit openings. Therefore, installation is straightforward in most industrial applications.

Configuration Breakdown

The 24701-28-05-00-090-04-02 follows a clear suffix code structure:

• 24701 : Proximity Probe Housing Assemblies

• 28 : 3300 XL 8mm probe with approval option

• 05 : 20 inches (0.5 metre) probe cable length

• 00 : No standoff adapter

• 090 : 9 inches probe penetration (C dimension)

• 04 : One 3/4-14 NPT plug only

• 02 : 3/4-14 NPT mounting thread

Each component is factory selected. Consequently, the assembly arrives ready for immediate installation.

Mechanical Construction

The housing body uses 303 stainless steel. The sleeve is made from 304 stainless steel. These materials provide excellent corrosion resistance and mechanical strength.

Total assembly weight is 1.8 kg (4.1 lb) typical without fittings. The maximum combined penetration dimension (C + D) is 13.5 inches (343 mm).

The probe cable length is fixed at 0.5 metres (20 inches). Note that the probe part number and serial number are not visible when fully assembled.

Included Components

This Proximity Probe Housing Assembly includes the following parts:

• A dome cover that screws into the housing body

• Threaded ports for conduit connections

• A probe sleeve of optional length

• O-rings for sealing

• A reverse mount proximity probe (3300 XL 8mm)

• A thread seal

Optional fittings are not included in this configuration. The assembly comes with one 3/4-14 NPT plug only.

Mounting and Installation

The 24701-28-05-00-090-04-02 uses 3/4-14 NPT mounting threads. This is a standard size for industrial conduit fittings. The lack of a standoff adapter means the probe mounts directly to the housing.

For proper installation, ensure the probe penetration depth matches your machine’s requirements. The 9-inch penetration suits many large turbines and compressors. Apply thread sealant to prevent leaks through the NPT connection.

Environmental and Mechanical Ratings

The stainless steel construction provides robust protection in industrial environments. The dome cover seals against debris and moisture. O-rings help maintain a tight seal around the probe sleeve.

While specific IP ratings are not listed, the housing design follows Bently Nevada’s standards for reliability. The assembly withstands typical vibration and temperature conditions found in rotating machinery monitoring.

Packaging and Delivery

The shipment includes:
