Description

Protecting critical vibration and position transducers in demanding industrial environments requires robust physical shielding. The 21000-28-05-00-040-04-02 is a heavy-duty, aluminum Proximity Probe Housing Assembly engineered by Bently Nevada to house and safeguard proximity probes, such as the 3300 XL series. This housing facilitates the external adjustment of the probe's relative position (gap) without requiring disassembly of the machine casing, streamlining maintenance and calibration procedures.

By enclosing the probe-to-extension cable connection, the 21000-28-05-00-040-04-02 prevents environmental ingress from moisture, oil, dust, and corrosive process agents. It is designed to withstand the severe vibrations and mechanical stresses typical of large rotating machinery casings, ensuring continuous, high-fidelity signal transmission to monitoring systems like the Bently Nevada 3500 Series.

Features

Aluminum Construction: Provides high structural strength and corrosion resistance while keeping the assembly lightweight.
External Gap Adjustment: Allows technicians to adjust probe depth and gap externally without dismantling the machine housing.
Environmental Protection: Seals the sensitive probe-to-cable connection from moisture, dust, lubricants, and contaminants.
Standard Conduit Interfaces: Designed with dedicated fitting ports to interface with protective conduit systems.

Applications

Steam and gas turbine generator sets
Centrifugal and axial compressors
Large industrial pumps and fans
Hydroelectric power generation units
Petrochemical and oil refinery rotating equipment

Installation Guidelines

Ensure the mating threads on the machine casing are clean, free of debris, and match the housing specifications before installation.
Apply thread sealant to the conduit entry ports to maintain environmental seal integrity and prevent fluid ingress.
Do not overtighten the probe locknut; adhere to the torque specifications provided in the Bently Nevada system manual to avoid damage to the probe sleeve.
Verify that the flexible conduit routing allows sufficient bend radius to prevent strain on the internal extension cables.
