Bently Nevada 21000-16-05-40-049-04-02 Proximity Probe Housing Assemblies

Description

The 21000-16-05-40-049-04-02 is a robust proximity probe housing assembly designed for industrial machinery vibration and position monitoring. This specific configuration features a 3300 XL 8 mm proximity probe (Option 16) with a 0.5 meter probe cable (Option 05), integrated into a housing assembly with a 4.0-inch standoff adapter (Option 40) and 4.9-inch probe penetration (Option 049). The assembly is equipped with a 3/4-14 NPT plug (Option 04) and utilizes a standard 3/4-14 NPT mounting thread (Option 02) for installation. This housing assembly protects the probe and its cable connection while facilitating precise gap adjustment, ensuring reliable operation in demanding environments. The 21000 series is engineered to meet API 670 standards, providing a secure, weather-resistant enclosure for critical sensing components. The design allows for the adjustment of the probe position through the standoff adapter, providing flexibility during commissioning and long-term asset management.

Installation Guidelines

• Verify that the mounting location allows for the required probe penetration and standoff adapter length.
• Ensure the machine case threads match the 3/4-14 NPT specification of this assembly.
• Use appropriate sealant on NPT threads to maintain the integrity of the housing environment.
• For probe penetration lengths greater than 300 mm (12 in), auxiliary sleeve support is required to mitigate vibration.
• Ensure that the probe cable is properly routed and protected within the conduit/housing system.
• During installation, avoid over-tightening fittings to prevent damage to the stainless steel sleeve or cable seals.
