While this remains under the critical 12-inch threshold that mandates internal dampening sleeves, installation geometry still matters. On a recent overhaul of a gas export compressor, high casing vibration was inducing side-view interference on un-counterbored casing holes. Ensuring a minimum 1.5-inch clearance around the probe tip eliminated signal noise and restored clean vibration voltage readings to the monitoring rack.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003ePackaging, Express Logistics \u0026amp; Warranty\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply Condition:\u003c\/strong\u003e Brand new, factory-sealed \u003cstrong\u003e\u003cspan style=\"color: #0056b3;\"\u003eBently Nevada\u003c\/span\u003e \u003cspan style=\"color: #d9534f;\"\u003e21000-16-10-20-083-03-02\u003c\/span\u003e\u003c\/strong\u003e housing assembly in original packaging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGlobal Logistics Express:\u003c\/strong\u003e Standard dispatch within 24–48 hours via FedEx, UPS, or DHL.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty Assurance:\u003c\/strong\u003e Fully covered by a 12-month factory replacement warranty from date of delivery.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eEngineering Selection \u0026amp; Mounting Checklist\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCasing Thickness Verification:\u003c\/strong\u003e Calculate casing depth to confirm an 8.3-inch penetration depth reaches the shaft target area.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Length Matching:\u003c\/strong\u003e Ensure the 1.0 m probe cable properly reaches the external junction box or extension cable connector.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConduit Reducer Setup:\u003c\/strong\u003e Utilize the supplied 3\/4 to 1\/2 NPT reducer to match existing site conduit runs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the purpose of the 20 option in this part number?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 20 code designates a 2.0-inch standoff adapter that spaces the housing away from the machine casing wall.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I adjust the penetration depth after mounting the housing?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, the housing sleeve allows an adjustment range of ±0.5 in (±13 mm) to set precise probe-to-shaft gap distances.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat indicates incorrect sleeve installation on deep casing mounts?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eExcessive noise or false vibration peaks on the monitor often signal sleeve resonance due to missing internal support.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this housing assembly certified for hazardous gas environments?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, it carries CSA explosion-proof ratings for Class I, Division 1 and 2, Groups C and D hazardous areas.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I select between 3\/4 NPT and other conduit fitting sizes?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe base mounting thread uses option 02 (3\/4-14 NPT), but the included fitting package provides a 1\/2-14 NPT reducer for flexibility.\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_007eb544-fd00-4b41-a22e-c953629fa721.png?v=1784785784\" alt=\"\"\u003e\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":45014025928886,"sku":"21000-16-10-20-083-03-02","price":227.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0722\/7863\/8774\/files\/21000-16-10-15-081-03-02.jpg?v=1786954714","url":"https:\/\/www.plcsparehub.com\/products\/21000-16-10-20-083-03-02-bently-nevada-proximity-probe-housing-assembly","provider":"Global PLC Spare Hub","version":"1.0","type":"link"}
