- Proximity Probe Housing Assemblies
- Aluminum body with 304 stainless steel sleeve
- 21000 and 24701 Proximity Probe Housing Assemblies
The 21000 and 24701 Proximity Probe Housing Assemblies are available with Canadian Standards Association (CSA) approvals. They are rated explosion proof for hazardous areas. Bently Nevada offers a probe support and oil seal (part number 37948-01) for long sleeves that must go through an inner bearing housing.
To externally mount proximity probes, use one of these allmetal Proximity Probe Housing Assemblies: 21000 aluminum probe housing assembly; 24701 stainless steel probe housing assembly The 21000 and 24701 Proximity Probe Housing Assemblies consist of the following parts:A dome cover that screws into the body of the housing; Threaded ports for conduit connections; A probe sleeve of optional length; 0-rings; A reverse mount proximity probe; A thread seal; Optional conduit fittings; An optional standoff adapter.
The 24701-34-05-20-018-03-02 Bently Nevada Proximity Probe Housing Assemblies may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Eddy current proximity sensor or system component, commonly used in the monitoring of industrial rotating machinery. Its working principle is based on high-frequency electromagnetic field coupling and the eddy current effect, and it is mainly used for non-contact measurement of shaft vibration, displacement, or axial motion.
This specific configuration is used when the measurement point is located on the machine shaft, requiring a certain distance between the probe housing and the machine surface.
Corrosive/Hazardous Environments: The 303 stainless steel housing is designed for environments such as offshore oil platforms, refineries, and chemical plants, where standard aluminum housings are prone to corrosion.
Spacing Requirements: A 2.0-inch spacing adapter is used to provide additional clearance between the housing and the machine housing, typically to accommodate insulation material (cladding) or to connect to a shaft with a visible recess.
Explosion-Proof Monitoring: CSA Type 4 certified housing suitable for monitoring vibration or speed of turbines and compressors in Class I Zone 1 and Zone 2 hazardous areas.
API 670 Compliant: Meets global standards for mechanical protection systems.
Efficient Maintenance: External clearance adjustments or probe replacements can be performed without disassembling the machine, reducing downtime.
High Temperature Resistance: Operates reliably in ambient temperatures ranging from -51°C to +177°C.
