Features:

  • Provides Durable Stainless Steel Construction For Industrial Environments
  • Supports Flexible Probe Penetration And Standoff Adapter Options
  • Includes Comprehensive Fittings And O-Ring Seals For Reliable Mounting
The Bently Nevada 24701-28-05-65-105-03-02 Proximity Probe Housing Assembly is designed for secure external installation of 3300 XL 8mm proximity probes. Its 303 stainless steel body and 304 stainless steel sleeve offer superior corrosion resistance compared with aluminum assemblies like the 21000, ensuring long-term reliability under demanding industrial conditions.

This housing assembly accommodates a 20 in (0.5 m) probe cable, a 6.5 in standoff adapter (Option C), and a 10.5 in probe penetration (Option D), allowing precise positioning of probes for various machinery layouts. It features multiple fittings, including a 3/4-14 NPT plug, a 3/4-14 to 1/2-14 NPT reducer, and cable seal grips suitable for cable sizes from 1/8 to 3/8 inches, providing enhanced flexibility over comparable 164818 and 21000 assemblies.

Included components such as O-rings, a threaded dome cover, reverse mount probe, thread seal, and optional conduit fittings make installation straightforward and secure. When compared to the 21000 aluminum or 164818 stainless steel housing assemblies, the 24701-28-05-65-105-03-02 offers a stronger structure and more adaptable probe mounting options, reducing maintenance needs and optimizing probe performance in industrial monitoring applications.

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

  • Physical Protection: Provides a CSA Type 4 seal, protecting the internal probe from industrial environments (water, dust, chemicals).
  • Gap Adjustment: Allows operators to adjust the gap between the probe and the measured axis via the rear of the housing without disassembling the machine.
  • API 670 Compliance: Designed to meet the American Petroleum Institute (API) 670 standard, it is a standard accessory for industrial-grade vibration monitoring systems.
  • Signal Transmission: The probe connects to an external extension cable via an internal 0.5-meter cable, ultimately connecting to the Proximitor sensor. The sensor converts impedance changes into a standard voltage signal, which is input to monitoring frames such as the 3500 Series.
  • Cable Connection: Typically uses a gold-coaxial connector internally, with NPT threaded holes on the housing for connecting to a conduit cable.
  • Explosion-Proof Certification: Supports explosion-proof installation, suitable for hazardous areas in North America, Class I, Div 1 & 2.
  • Steam turbines and gas turbines: Monitoring shaft vibration, shaft displacement, and rotational speed.
  • Large compressors and pumps: Providing enhanced corrosion resistance in corrosive environments or outdoor applications using stainless steel.
  • Hazardous area monitoring: Monitoring points for rotating equipment requiring explosion-proof certification in oil refineries and chemical plants.
Description
The Bently Nevada 24701-28-05-65-105-03-02 Proximity Probe Housing Assembly is engineered for reliable external mounting of 3300 XL 8mm proximity probes, delivering superior durability and precise installation compared with the aluminum 21000 probe housing assembly. Its 303 stainless steel body and 304 stainless steel sleeve resist corrosion while ensuring long-term operational stability in industrial environments.

This assembly accommodates a 20 in (0.5 m) probe cable length and features a standoff adapter of 6.5 in (Option C) and a probe penetration of 10.5 in (Option D), offering flexible installation depths that adapt to various machinery layouts. Compared with the 21000 housing, the 24701-28-05-65-105-03-02 provides enhanced strength and expanded fitting options, including a 3/4-14 NPT plug, a 3/4-14 to 1/2-14 NPT reducer, and multiple cable seal grips for cable diameters ranging from 1/8 to 3/8 inches.

Mounting is secured via 3/4-14 NPT threading, compatible with common industrial setups. The assembly includes O-rings, a dome cover, threaded ports for conduit, a reverse mount probe, thread seal, optional conduit fittings, and an optional standoff adapter, integrating all essential components for a complete installation. When compared to the 164818 Proximity Probe Housing Assembly, the 24701-28-05-65-105-03-02 offers improved stainless steel durability and customizable probe penetration options.

Designed for industrial reliability, the Bently Nevada 24701-28-05-65-105-03-02 ensures precise probe alignment and robust sealing, reducing maintenance cycles and enhancing probe life. Its compatibility with all-metal assemblies like the 21000 and 164818 series allows users to select the housing type that best fits operational requirements while maintaining consistent performance and protection for the 3300 XL 8mm probes.
