Description：

The Bently Nevada 24701-28-05-00-038-04-02 is a Proximity Probe Housing Assembly developed to provide a secure and service-friendly mounting solution for proximity probes used in rotating machinery monitoring systems. It enables reliable installation of shaft vibration and position probes while allowing convenient access for inspection, probe adjustment, and replacement without dismantling the machine.

The housing is widely used in applications where radially mounted proximity probes are required to monitor shaft vibration, shaft position, or Keyphasor® reference signals. By creating a stable mounting interface through the machine casing, the assembly helps maintain consistent probe positioning and contributes to accurate, long-term measurement performance.

For installations with limited mounting space, the 24701-28-05-00-038-04-02 can be incorporated into compact monitoring arrangements similar to those used with Bently Nevada compact probe housing configurations. These solutions are suitable for machinery where conventional probe housings cannot be accommodated because of restricted clearance around the bearing housing or machine frame.
