Description

The 21000-28-05-00-080-03-02 is a Bently Nevada proximity probe housing assembly, specifically configured with a 3300 XL 8 mm probe (Option 28) and a 0.5 m (20 in) probe cable (Option 05). This assembly is designed to provide a secure and weather-tight environment for proximity probes, ensuring reliable performance in demanding industrial vibration and position monitoring applications. The housing is constructed with an aluminum body and a stainless steel sleeve, meeting API 670 standards for externally mounted proximity probe housings.

This specific configuration (Option 00) excludes a standoff adapter, providing a direct installation profile. The 8.0 in probe penetration depth (Option 080) and 3/4-14 NPT mounting thread (Option 02) facilitate precise integration into machine cases. The inclusion of a cable seal grip (Option 03) ensures protection against environmental contaminants. This unit is compatible with 3300 XL transducer systems, offering standard hazardous area approval capabilities aligned with the 3300 XL 8 mm probe series.

Installation Guidelines

• Ensure the probe cable length is sufficient for the sleeve length; the probe lead must be longer than the sleeve.
• For penetration lengths greater than 300 mm (12 in), additional sleeve support is required to prevent resonance.
• Utilize the provided cable seal grip to prevent moisture ingress at the conduit entry.
• When installing in hazardous areas, ensure the selected approvals meet local regulatory requirements and the system is installed per control drawing 140979.

Compliance and Certifications

• RoHS Directive 2011/65/EU
• CSA certified for explosion-proof applications (when ordered with appropriate housing and fittings)
