The 3\/4-14 NPT mounting thread ensures secure installation in standard conduit ports. The included fitting kit provides flexibility for cable entry, accommodating multiple cable diameters. Weighing only 1.1 kg (2.4 lb), this housing is lightweight yet robust, reducing stress on mounting points.\u003c\/p\u003e\u003ch2\u003eApplications and Use Cases\u003c\/h2\u003e\u003cp\u003eThis Bently Nevada 21000-34-00-20-039-03-02 is ideal for externally mounted proximity probes in turbo-machinery, pumps, compressors, and generators. In a refinery setting, the housing's CSA Type 4 rating and compliance with API 670 make it suitable for hazardous areas. The 1.0 m probe cable length simplifies routing to the monitor, while the visible probe identification (P\/N and S\/N) aids in maintenance tracking.\u003c\/p\u003e\u003ch2\u003eInstallation and Setup\u003c\/h2\u003e\u003cp\u003eWhen installing the 21000-34-00-20-039-03-02, ensure the mounting thread (3\/4-14 NPT) is clean and properly sealed. Use the provided cable seal grip to secure the probe cable, choosing the appropriate grommet for your cable diameter. The standoff adapter must be correctly oriented to achieve the desired probe penetration. Verify that the probe tip is at the recommended gap for optimal performance.\u003c\/p\u003e\u003ch2\u003eMaintenance and Reliability\u003c\/h2\u003e\u003cp\u003eRegular inspection of the housing's O-rings and thread seal prevents moisture ingress, extending the life of the internal probe. The aluminum body resists corrosion, while the stainless steel sleeve protects the probe from wear. Periodic checks of the cable connections ensure signal integrity. This housing is designed for long-term reliability, reducing unplanned downtime and maintenance costs.\u003c\/p\u003e\u003ch2\u003eCompatibility and Integration\u003c\/h2\u003e\u003cp\u003eThe 21000-34-00-20-039-03-02 is compatible with Bently Nevada 3300 XL proximity probe systems. It integrates seamlessly with Bently Nevada monitors and diagnostic equipment. The housing's aluminum and stainless steel construction makes it suitable for intrinsically safe applications when used with approved barriers.\u003c\/p\u003e\u003ch2\u003eSelection Guide and Purchasing Advice\u003c\/h2\u003e\u003cp\u003eBefore ordering, confirm the probe cable length (1.0 m) and the fitting options meet your installation requirements. Verify the mounting thread size (3\/4-14 NPT) matches your existing conduit. For additional support, PLC Source PRO offers genuine Bently Nevada parts with a 12-month warranty.
