Features:
- Interface Between the Proximity Probe and Industrial Monitoring Equipment
- Combines Capability of Probe Sensing with Connector Protection
- Operates in Conjunction with the 3300 XL Series and Selectable Hazardous Area Approvals
The 21000-34-05-15-029-04-02 operates as the Proximity Probe Housing Assembly, providing reliable proximity sensing for critical rotating machinery monitoring systems. It continuously delivers accurate displacement and measurement through the 3300 XL 8mm probe with 0.5 m (20 in) probe cable length and 2.9 in probe penetration capability. Seamless integration is standard with the 21000-34-05-15-029-04-02, however using the optional standoff adapter with minimum 1.5 in (38 mm) length will allow flexible mounting configurations in various industrial applications. The 21000-34-05-15-029-04-02 has made improvements in several areas over previous probe housing designs in addition to incorporating selectable hazardous area approvals and connector protector features within the assembly.
The 21000-34-05-15-029-04-02 provides essential proximity sensing functions common to the entire monitoring system, and is a critical component of the measurement path, directly affecting the proper, normal operation of the overall machinery protection system. One 21000-34-05-15-029-04-02 probe housing assembly is required per monitoring point depending on the desired measurement configuration. The 21000-34-05-15-029-04-02 occupies a dedicated mounting position with 3/4-14 NPT mounting thread and one 3/4-14 NPT plug fitting included, and is always located at the machinery access point (the dedicated probe installation position).
For applications requiring standoff extension, the monitoring system requires the 21000-34-05-15-029-04-02 standoff adapter option with minimum 1.5 in (38 mm) length installed in the assembly.In addition to standard direct mounting operation, the standoff configuration also performs penetration depth adjustment. The 21000-34-05-15-029-04-02 dual configuration executes measurement optimization using the internal probe positioning specified in the housing options. Using this method, the standoff system continually monitors the probe penetration depth relative to the target surface. If the system detects that the probe is no longer providing stable signal output (outside configured proximity/tolerance levels), it will automatically require verification of the 21000-34-05-15-029-04-02 installation and and place an event in the System Event List.
The 21000-34-05-15-029-04-02 Proximity Probe Housing Assembly may still be available for purchase and support from authorized distributors beyond standard manufacturer lead times.

- Physical Connection: The housing uses threaded ports (3/4-14 NPT) for conduit connections to protect the internal wiring.
- Signal Interface: It houses a reverse mount proximity probe that connects via an extension cable to a Proximitor Sensor, which then outputs a signal to monitoring systems like the Bently Nevada 3500.
- Maintenance Access: Designed to allow external access for gap adjustment or probe replacement without machine disassembly.
- Hazardous Area Ratings: Certified for Explosion Proof applications by the Canadian Standards Association (CSA).
- North America: Class 1, Divisions 1 & 2 (Groups C and D); Class 2, Divisions 1 & 2 (Groups E, F, and G).
- Europe: Complies with the CE mark and BASEEFA/CENELEC standards for Zones 0, 1, and 2 (Groups I, IIA, IIB, and IIC) when used with approved barriers.
- Enclosure Rating: Certified as CSA Type 4 (weatherproof/dust-tight).
- Industry Standard: Fully compliant with API 670 for externally mounted proximity probe housings.
- Vibration & Position Monitoring: Primarily used to mount probes that monitor shaft vibration, axial position, and speed on critical rotating machinery like turbines, compressors, and pumps.
- Hostile Environments: Used in oil and gas, power generation, and chemical processing where protection against explosive gases or harsh weather is required.
- Retrofitting: Often used in applications where internal mounting is not possible or where frequent probe access is necessary for calibration.
