Key Features and Configuration
This specific configuration belongs to the widely utilized 21000 Aluminum series. The modular design allows for precise probe positioning relative to the target shaft. Furthermore, the assembly includes a specialized conduit for cable protection. This prevents mechanical damage and interference from external electrical noise. The -15-030-04-02 suffix determines the specific sleeve length and thread options for the installation site. Consequently, this unit offers a tailored fit for various bearing housing thicknesses.
Functional Characteristics
The housing acts as a protective barrier against moisture, oil, and debris. It significantly simplifies the calibration process of proximity sensors. Since the probe is accessible from the exterior, downtime during maintenance is greatly reduced. Additionally, the aluminum body provides excellent thermal dissipation. This feature helps maintain sensor accuracy during fluctuating machine temperatures. The assembly also supports a wide range of Bently Nevada 3300 XL 8mm proximity probes.
