To ensure accurate linearization over the 2.0 mm measuring range, the system necessitates precise gap voltage validation. The converter centers its output characteristic around a nominal target of -10 VDC, which represents the mid-point of the physical measurement gap. Maintenance of this -10 VDC baseline is mandatory during static commissioning; significant deviations indicate mechanical misalignment, transducer saturation, or degradation of the conductive target surface.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the CON021 converter be used with different Epro PR642x series probes?\u003c\/p\u003e\n\u003cp\u003eA: The converter is calibrated as part of a matched system. Replacing the transducer probe requires checking the calibration certificate to ensure that the Incremental Scale Factor (ISF) and linearity error specifications remain within system tolerances.\u003c\/p\u003e\n\u003cp\u003eQ: Is the IP66 rating maintained if the cable is cut or spliced during field installation?\u003c\/p\u003e\n\u003cp\u003eA: No. The IP66 rating applies to the factory-sealed sensor head and cable assembly. Any field splicing or modification compromises the environmental integrity of the seal, potentially allowing fluid ingress into the sensor tip.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the sensor in a rigid, vibration-isolated bracket to minimize extraneous mechanical noise and prevent housing fatigue.\u003c\/li\u003e\n\u003cli\u003eMaintain a minimum shaft diameter of 25 mm for the target area to ensure linear flux density and accurate readings.\u003c\/li\u003e\n\u003cli\u003eEnsure the initial air gap is set to 0.5 mm using a non-metallic feeler gauge to prevent contact-induced tip damage during operation.\u003c\/li\u003e\n\u003cli\u003eRoute the PTFE-insulated cable through grounded metallic conduit, keeping the lead away from high-current AC power lines to minimize induced electromagnetic interference.\u003c\/li\u003e\n\u003cli\u003eInspect all mechanical threads for burrs or contaminants prior to installation to ensure a flush mount against the housing, preventing resonance.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"EMERSON","offers":[{"title":"Default Title","offer_id":53009099325749,"sku":"CON021+PR6423\/002-030","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/CON010_PR6423010-120_8eb573e7-99f8-425a-8f69-8f272405e3de.png?v=1781683998","url":"https:\/\/www.5gplc.com\/products\/pr6423-002-030-con021-eddy-current-sensor-emerson-epro","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
