Bently Nevada 21000-16-05-30-026-04-02 Proximity Probe Housing Assembly

Description

The 21000-16-05-30-026-04-02 is a robust Proximity Probe Housing Assembly designed for industrial machinery vibration and position monitoring. This configuration utilizes a 3300 XL 8 mm proximity probe integrated into an aluminum body with a 304 stainless steel sleeve, meeting API 670 standards for externally mounted proximity probe housings. The assembly ensures critical sensor protection and accurate gap management in demanding environments.

This unit features a 0.5 m probe cable, a 3.0 inch standoff adapter, and a 2.6 inch probe penetration depth. The assembly is configured with a 3/4-14 NPT mounting thread and includes a 3/4-14 NPT plug fitting, providing a secure and sealed installation for the probe within the machine casing. It is engineered to prevent resonance and allow for precise alignment of the transducer tip relative to the target surface.

Installation Guidelines

Ensure the probe lead is longer than the sleeve to facilitate connection. For penetration lengths exceeding 300 mm (12 inches), install additional sleeve support to mitigate resonance. When installing the 3/4-14 NPT fittings, ensure proper thread sealing practices are followed to maintain environmental integrity. Verify nominal probe gap during installation as per the specific transducer system user guide (e.g., 141078 for 3300 XL 8 mm systems).
