Description

The 21000-16-10-00-120-03-02 is a specialized proximity probe housing assembly designed to protect and position Bently Nevada transducers in industrial machinery. This configuration features an aluminum body with a 304 stainless steel sleeve, configured with a 3300 XL 8 mm probe (Option 16), a 1.0 m probe cable (Option 10), and no standoff adapter (Option 00). The assembly provides a 12.0 in probe penetration (Option 120) and includes two 3/4-14 NPT explosion-proof fittings (Option 03) along with a 3/4-14 NPT mounting thread (Option 02). This housing assembly ensures consistent, stable mounting for vibration monitoring and axial position measurement, aligning with API 670 standards for externally mounted proximity probe housings. The 21000 series is constructed for durability in harsh environments, utilizing high-quality materials to maintain the integrity of the sensing chain while allowing for adjustable penetration depths to suit specific machine installation requirements.

Installation Guidelines

Ensure the housing is installed using appropriate thread sealant for the 3/4-14 NPT connections. For probe penetration depths greater than 300 mm (12 in), auxiliary sleeve support is required to minimize potential resonance. Verify that the probe cable length is sufficient for the intended standoff distance. If counter-boring the machine case, ensure no metal components interfere with the probe's side-view or rear-view sensitivity zone.
