Features:

  • Through-Case Mounting Solution for 3300 XL 8 mm Proximity Probe with Connector
  • PPS Housing Construction with Corrosion-Resistant Stainless Steel Fitting Assembly
  • Compatible with Radial Vibration, Keyphasor, and Intrinsically Safe Monitoring Applications
The 31000-16-05-00-071-03-02 operates as the Proximity Probe Housing Assembly in rotating machinery protection systems, providing secure through-case mounting and continuous environmental protection for the installed 3300 XL 8 mm probe with connector. It maintains probe positioning and 0.5 m (20 in) cable integrity while enabling external access for gap adjustment or probe replacement without machine disassembly. Seamless maintenance access is standard with the 31000-16-05-00-071-03-02, however ensuring the machine casing is affixed to the bearing allows accurate relative vibration signal acquisition for radial measurements. The 31000-16-05-00-071-03-02 has made improvements in chemical resistance and structural durability over previous housing designs in addition to incorporating universal cable sealing compatibility within the probe installation.

The 31000-16-05-00-071-03-02 provides essential protection and mounting functions common to the entire transducer path, and is a critical component of the measurement chain, directly affecting the proper, normal operation of the overall monitoring system. One 31000-16-05-00-071-03-02 housing assembly is required per probe location depending on the measurement point requirement. The 31000-16-05-00-071-03-02 occupies a single installation position through the machine case with no standoff adapter and is always configured with 7.1 inches probe penetration depth to reach the target surface using the 3/4-14 NPT mounting thread.

For dual proximity probe applications measuring shaft axial position, the 31000-16-05-00-071-03-02 should not be used; housing 21022 should be selected instead. In addition to standard radial vibration monitoring, the 31000-16-05-00-071-03-02 configuration also performs reliable environmental sealing using the supplied fittings. The 31000-16-05-00-071-03-02 fitting assembly executes cable protection using two plugs, one 3/4-14 NPT fitting, one 3/4-14 to 1/2-14 NPT SST reducer, and the cable seal grip with grommets specified in the housing options. Using this method, the sealing system continually accommodates the specified cable ranges. If the installation requires cable diameters from 1/8 to 3/16 inches, 1/4 to 5/16 inches, or 5/16 to 3/8 inches, it will automatically form a proper seal and maintain environmental isolation for the probe and extension cable.

The 31000-16-05-00-071-03-02 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).
