Bently Nevada 21000-28-05-00-133-04-02 Proximity Probe Housing Assemblies

Description

The Bently Nevada 21000-28-05-00-133-04-02 is a 21000 Series proximity probe housing assembly designed for the external mounting and protection of proximity probes used in shaft vibration and position monitoring applications. The housing provides convenient external access to the proximity probe and its extension cable, allowing probe gap adjustment or replacement without disassembling the machine, thereby reducing maintenance time and improving equipment availability. The assembly features an aluminum housing with a 304 stainless steel probe sleeve and complies with API 670 requirements for externally mounted proximity probe housings. This configuration includes a 3300 XL 8 mm proximity probe with selectable hazardous area approvals, a 0.5 m (20 in) probe cable, no standoff adapter, a 13.3 in probe penetration length, one 3/4-14 NPT plug, and a 3/4-14 NPT mounting thread.
