Once the housing is threaded into the machine, use the internal adjustment sleeve to set the probe gap. Typically, the probe is gapped to -10.0 VDC (center of the 80-mil linear range). Ensure the standoff adapter is tightly sealed with industrial-grade thread sealant to maintain the explosion-proof rating of the enclosure.\u003c\/p\u003e\n\u003ch3\u003eCable Sealing\u003c\/h3\u003e\n\u003cp\u003eThis assembly includes a cable seal grip (Option 03). You must select the correct grommet size corresponding to your extension cable diameter. This seal prevents the passage of explosive gases through the conduit system. Tighten the compression nut until the grommet fully encompasses the cable, ensuring no voids are present.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eEngineering Advantages\u003c\/h2\u003e\n\u003cp\u003eThe CA24701 assembly eliminates the need for internal probe brackets, which can be difficult to service. By moving the probe mounting point to the exterior of the machine, it allows for \"hot-swapping\" or adjusting sensors while the machine remains in a safe standby state, provided the area is non-hazardous during the specific maintenance window.\u003c\/p\u003e\n\u003cp\u003eThe 303 Stainless Steel construction offers superior longevity compared to aluminum housings, particularly in coastal or offshore environments where salt spray causes rapid oxidation. Furthermore, the inclusion of the 3300 XL 8mm probe ensures the highest level of signal stability and resistance to \"glitch,\" providing the reliable data required by Bently Nevada 3500 series machinery protection systems.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eTechnical FAQs\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ1: Why is the Mounting Thread (Option 02) mandatory for this configuration?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA1: Because this model includes a 2.0-inch standoff adapter, a 3\/4-14 NPT mounting thread is required to mechanically couple the adapter to the machine casing while maintaining the flameproof path.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Can I replace the internal probe without buying a whole new housing?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA2: Yes. The internal 3300 XL 8mm probe is a modular component. However, the replacement probe must match the 0.5-meter cable length to fit properly within the housing's internal dimensions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: What happens if my cable is slightly larger than the provided grommets?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA3: Do not force the cable. The Option 03 kit provides three different grommet ranges. If your cable falls outside the 1\/8\" to 3\/8\" range, you must source a compatible NPT cable gland to maintain the explosion-proof integrity of the assembly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: Is this housing suitable for underwater applications?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA4: While the housing is highly water-resistant (IP66\/IP67 rated with proper seals), it is designed for explosion-proof atmospheric protection, not continuous subaquatic immersion.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":52668325331307,"sku":"CA24701-28-05-20-034-03-02","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/3227\/0443\/files\/ca24701-28-05-20-034-03-02-i34ttqwlzxl_1b641b46-dee5-43d6-b016-707f0f7098d8.jpg?v=1765521292","url":"https:\/\/www.plcprotech.com\/products\/ca24701-28-05-20-034-03-02-bently-nevada-explosion-proof-housing-assembly","provider":"PLC ProTech Ltd.","version":"1.0","type":"link"}
