Do not attempt to modify the probe sleeve length in the field, as this will void your hazardous area certification.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use this with non-Bently probes?\u003c\/strong\u003e\u003cbr\u003eA: We strongly advise against mixing components. The system accuracy, particularly in API 670 compliant machinery, relies on the matched impedance of Bently Nevada probes and housings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the benefit of the NPT plug included in this configuration?\u003c\/strong\u003e\u003cbr\u003eA: The NPT plug seals unused conduit ports, which is a mandatory safety requirement for maintaining the explosion-proof integrity of Class I, Division 1 enclosures.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0722\/7863\/8774\/files\/21000_CA21000_Proximity_Probe_Housing_Assembly_6e858fd0-30b5-48e6-858e-63405295fa24.png?v=1777369254\" alt=\"\"\u003e\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45014034383030,"sku":"21000-28-05-20-066-04-02","price":217.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7863\/8774\/files\/21000-16-10-00-066-03-02_22ff3cd7-bd8b-4bcd-b72c-62a0579dd3d3.jpg?v=1780910205","url":"https:\/\/www.plcsparehub.com\/products\/bently-nevada-21000-28-05-20-066-04-02-proximity-probe-housing","provider":"Global PLC Spare Hub","version":"1.0","type":"link"}
