Quick Detail

Description

21000-34-05-15-029-04-02 Proximity Probe Housing Assemblies are designed for external mounting of proximity probes in industrial automation and machinery protection systems. The 21000-34-05-15-029-04-02 housing integrates a 3300 XL 8 mm proximity probe with connector protector and supports selectable hazardous area approvals, making 21000-34-05-15-029-04-02 suitable for turbine, compressor, and pump monitoring installations.

The 21000-34-05-15-029-04-02 Proximity Probe Housing Assembly features a 0.5 m (20 in) probe cable, a 1.5 in standoff adapter (Option C), and a 2.9 in probe penetration depth (Option D). The mounting interface uses a 3/4-14 NPT thread with one 3/4-14 NPT plug, allowing direct connection to conduit systems commonly used in automation cabinets and field junction boxes. The aluminum housing body with a 304 stainless steel sleeve provides mechanical protection for the probe, while the typical mass of 21000-34-05-15-029-04-02 is 1.1 kg without fittings.

Each 21000-34-05-15-029-04-02 Proximity Probe Housing Assembly includes a dome cover, threaded conduit ports, probe sleeve, O-rings, thread seal, and optional conduit fittings. The 21000-34-05-15-029-04-02 is CSA approved, rated explosion-proof, and compliant with API 670 requirements for externally mounted proximity probe housings in automated monitoring systems.

Applications

External Mounting of 3300 XL 8 mm Proximity Probes
21000-34-05-15-029-04-02 is used to externally mount 3300 XL 8 mm proximity probes on turbines, compressors, and large pumps where internal mounting is not possible. With a probe penetration of 2.9 in and a 1.5 in standoff adapter, 21000-34-05-15-029-04-02 allows accurate shaft position and vibration measurement while maintaining correct probe-to-target distance in automated monitoring systems.

Hazardous Area Machinery Protection
21000-34-05-15-029-04-02 is applied in hazardous industrial areas such as oil and gas processing units and power generation plants. The aluminum body, CSA approval, and explosion-proof rating enable 21000-34-05-15-029-04-02 to support intrinsically safe proximity probe installations connected to machinery protection racks and DCS systems.

Conduit-Based Field Installation
With a 3/4-14 NPT mounting thread and one 3/4-14 NPT plug, 21000-34-05-15-029-04-02 is used in automation projects requiring rigid conduit wiring. The 0.5 m probe cable supports direct routing to junction boxes or signal conditioners without additional adapters.

Specifications

Competitive Advantage

Defined Probe Position Control
21000-34-05-15-029-04-02 combines a fixed sleeve length, 2.9 in probe penetration, and controlled standoff distance to help technicians set precise probe positioning during installation, reducing repeated adjustments in the field.

Mechanical Protection in Harsh Environments
The aluminum housing with a 304 stainless steel sleeve allows 21000-34-05-15-029-04-02 to shield the probe from oil spray, dust, and mechanical contact. The typical weight of 1.1 kg supports rigid mounting without adding excessive load to machine casings.

Standardized Installation for Automation Projects
21000-34-05-15-029-04-02 follows API 670 requirements for externally mounted proximity probe housings, enabling direct use in automation and machinery protection projects where standardized components are required across multiple machines.
