Features:

  • Interface Between the Proximity Probe and External Machinery Mounting Surface
  • Combines Capability of Probe Protection with Explosion-Proof Hazardous Area Certification
  • Operates in Conjunction with the 3300 XL 8mm Probe Series and Standard Bently Nevada Monitoring Systems
The Bently Nevada 21000-16-10-00-077-03-02 Proximity Probe Housing Assembly serves as the external mounting solution for proximity probes in industrial machinery monitoring applications, providing secure mechanical installation and environmental protection for the internal probe components. It continuously houses the reverse mount proximity probe with a penetration depth of 7.7 inches and maintains sealed integrity through O-rings and thread seals to protect the probe against harsh industrial conditions. Seamless integration with standard conduit systems is standard with the 21000-16-10-00-077-03-02, however using the included cable seal grip with grommets will allow proper cable management for varying cable sizes from 1/8 to 3/8 inches in the event of different installation requirements. The 21000-16-10-00-077-03-02 has made improvements in several areas over previous housing designs in addition to incorporating CSA explosion-proof certification for hazardous area operation within industrial facilities.

The 21000-16-10-00-077-03-02 provides essential protection functions common to the entire proximity measurement path, and is a critical component of the vibration monitoring system, directly affecting the proper, normal operation of the overall machinery condition monitoring system. One 21000-16-10-00-077-03-02 housing assembly is required per probe installation depending on the desired mounting configuration. The 21000-16-10-00-077-03-02 occupies the external mounting position on machinery casings and is always located at the measurement point (designated penetration location, the dedicated probe housing position).

For Dual Cable Size applications, the 21000-16-10-00-077-03-02 system accommodates multiple cable diameters through the included grommet set installed in the cable seal grip. In addition to standard single cable size operation, the grommet configuration also performs proper sealing. The 21000-16-10-00-077-03-02 cable sealing system executes protection using the internal grommet sizing specified in the fitting options. Using this method, the cable seal system continually maintains environmental isolation for the probe cable. If the system detects that the cable seal is no longer providing proper fit (outside configured grommet size ranges), it will automatically require grommet replacement and ensure continued protection of the internal probe components.

The 21000-16-10-00-077-03-02 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).
