Description

21000-28-05-00-105-04-02 is a robust proximity probe housing assembly designed for industrial machinery protection and condition monitoring. This configuration includes a 3300 XL 8mm probe (Option 28) with selectable hazardous area approvals, providing precise eddy-current displacement measurement for critical rotating equipment. The housing assembly features an aluminum body with a 304 stainless steel sleeve, ensuring protection for the probe and cable interface in harsh operating environments. This specific unit is configured for a 0.5 m probe cable length (Option 05) and a 10.5-inch probe penetration depth (Option 105). It is supplied without a standoff adapter (Option 00) and includes a 3/4-14 NPT plug (Option 04) for standard conduit interface, with a 3/4-14 NPT mounting thread (Option 02).

Features

3300 XL 8mm Probe (Option 28): Provides industry-standard eddy-current shaft vibration and axial position measurement.
Hazardous Area Capability: Configured for selectable hazardous area approvals, suitable for demanding environments.
Aluminum Body Construction: Durable housing assembly with 304 stainless steel sleeve for corrosion resistance and mechanical protection.
Compact Integration: Designed to mount directly to the machine case, shielding the probe lead and connector.
Fittings (Option 04): Includes a 3/4-14 NPT plug for secure cable entry and conduit sealing.

Applications

Power generation equipment (turbines, generators)
Oil and gas processing (compressors, pumps)
Petrochemical and industrial rotating machinery
Critical machinery protection where API 670 standards apply

Installation Guidelines

Ensure the probe penetration length (Option D) is compatible with the machine case and required nominal gap.
For penetration lengths between 1.0 and 2.0 inches, counter-boring the machine case may be necessary to mitigate side-view effects.
If penetration length (C + D) exceeds 300 mm (12 in), additional sleeve support is required to prevent resonance.
Standard torque requirements apply for NPT conduit connections to maintain environmental seal.
