Features:

  • Direct-mounted design without standoff adapter for simplified probe installation and stable positioning.
  • CSA Type 4 certified enclosure with API 670 compliance for hazardous area applications.
  • Flexible installation support including long sleeve guidance and optional probe support solutions.
The Bently Nevada 21000-16-05-00-090-04-02 Proximity Probe Housing Assembly is designed for external mounting of 3300 XL 8 mm probes in industrial monitoring systems. It provides a stable mechanical structure for probe installation and positioning. The Bently Nevada 21000-16-05-00-090-04-02 is configured for standard industrial applications where fixed installation is required. Its design supports consistent measurement alignment. It is suitable for monitoring environments with strict installation requirements.

The Bently Nevada 21000-16-05-00-090-04-02 includes a probe cable length of 0.5 m (20 in) and a probe penetration of 9.0 in. It uses a 3/4-14 NPT mounting thread for secure mechanical connection. The Bently Nevada 21000-16-05-00-090-04-02 is supplied with one 3/4-14 NPT plug as its fitting component. The absence of a standoff adapter results in a more direct installation structure. This configuration supports straightforward integration into industrial systems.

The Bently Nevada 21000-16-05-00-090-04-02 is certified as a CSA Type 4 enclosure and is suitable for intrinsically safe applications. It complies with API 670 standards for externally mounted proximity probe housings. Compared with the 164818 Compact Proximity Probe Housing, the Bently Nevada 21000-16-05-00-090-04-02 is intended for standard installations rather than compact space-limited environments. For extended sleeve applications, additional support is required when exceeding 304 mm (12 inches). Bently Nevada also provides dedicated support accessories such as part number 37948-01 and custom solutions.

The 21000-16-05-00-090-04-02 Bently Nevada Proximity Probe Housing Assembly may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • System Collaboration: As front-end hardware, it perfectly matches 3500 or 2300 monitoring systems, ensuring seamless data transmission from the physical layer to the monitoring layer.
  • Probe Adaptation: The flexible internal space design of the housing can accommodate eddy current probes of different diameters and frequencies, adapting to various measurement accuracy requirements.
  • Standardized Interface: Adopting universal industrial-grade threads and connector standards, it facilitates direct connection with existing field wiring conduits or explosion-proof flexible conduits.
  • Architectural Integration: Supports easy integration into the factory's existing offline inspection or online remote monitoring network through different brackets and adapters.
  • Offline Calibration: Supports pre-locking of the probe's zero position externally, significantly reducing on-site installation and debugging time.
  • Quick Access: The specially designed cover structure allows technicians to quickly access the sensor, enabling maintenance without disassembling large mechanical parts.
  • Gap Control: Through the housing's built-in adjustment mechanism, micron-level precise control of the gap between the probe and the axial surface can be achieved, ensuring the signal remains within the optimal linear range.
  • Flexible Layout: The compact design allows for multi-angle installation within the confined space of the bearing housing, accommodating both radial and axial bidirectional monitoring.
  • Marine Propulsion: Installed in the main propulsion shaft system of large ocean-going vessels to monitor the vibration trajectory of the shafting during deep-sea navigation.
  • Mining Equipment: Used in the transmission systems of heavy-duty ball mills or crushers to protect core sensors in environments with strong vibration and high dust levels.
  • Paper Machinery: Deployed on the bearings of high-speed drying cylinders in paper machines to monitor stability under high humidity and high-temperature cyclic conditions.
  • Pharmaceutical Centrifuges: In high-speed separation equipment in biopharmaceuticals, ensuring precise displacement control of the rotor in a clean and high-speed operating environment.
Description
Designed for use with 3300 XL 8 mm proximity probes, the Bently Nevada 21000-16-05-00-090-04-02 Proximity Probe Housing Assembly supports stable external installation in industrial systems. It is configured without a standoff adapter, allowing a direct mounting structure. The Bently Nevada 21000-16-05-00-090-04-02 is suitable for applications requiring fixed probe positioning and standardized installation.

Installation parameters include a probe cable length of 0.5 m (20 in) and a probe penetration depth of 9.0 in. The housing uses a 3/4-14 NPT mounting thread for mechanical connection. With only one 3/4-14 NPT plug included as fittings, the Bently Nevada 21000-16-05-00-090-04-02 maintains a simplified structural configuration.

Hazardous area suitability is supported through CSA Type 4 enclosure certification. Both 21000 aluminum and 24701 stainless steel housings are available for intrinsically safe applications and comply with API 670 standards for externally mounted probe housings. Compared with the 164818 Compact Proximity Probe Housing, the Bently Nevada 21000-16-05-00-090-04-02 is more suited for standard installations rather than space-restricted configurations.

For long sleeve applications, sleeve length must be matched to installation location, and probe lead length must exceed sleeve length. When sleeve lengths exceed 304 mm (12 inches), additional sleeve support is required to reduce vibration. Bently Nevada also provides probe support and oil seal part number 37948-01, along with custom sleeve support solutions.
