The 32 mm sensor head detects dynamic changes in distance to an electrically conductive steel target across a 0 Hz to high-frequency spectrum. By outputting raw high-frequency electromagnetic field responses to an external signal converter module, the transducer captures radial shaft vibration, axial position, and rotor eccentricity in rotating machinery assemblies without mechanical wear.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003ePR6426\/000-030\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eEmerson (EPRO)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eGermany\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eNot specified (Standard probe head assembly)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eFlange: 80 x 40 x 8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-35 to +180 deg C (short term to +200 deg C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003ePowered via connected CON series signal converter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor Type\u003c\/td\u003e\n\u003ctd\u003e32 mm Eddy Current Displacement Transducer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Air Gap\u003c\/td\u003e\n\u003ctd\u003e5.5 mm (0.22 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Range\u003c\/td\u003e\n\u003ctd\u003eStatic +\/- 4.0 mm (+\/- 0.16 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncremental Scale Factor\u003c\/td\u003e\n\u003ctd\u003e2 V\/mm (50.8 mV\/mil)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTarget Material\u003c\/td\u003e\n\u003ctd\u003eElectrically conducting steel (recommended shaft dia \u0026gt;= 200 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLinearity Error\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; +\/- 1.5% after calibration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure Resistance\u003c\/td\u003e\n\u003ctd\u003eSensor head: 6500 hPa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eCON 011\/91, CON 021\/91, CON 041\/91 signal converters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProbe Calibration \u0026amp; Rotor Dynamic Tracking\u003c\/h3\u003e\n\u003cp\u003eThe transducer relies on eddy-current probe scaling tuned to an Incremental Scale Factor (ISF) of 2 V\/mm. When installed, engineers perform gap voltage validation to position the probe tip within its linear measurement region around the 5.5 mm nominal gap center. This setup ensures optimized signal linearity (\u0026lt; +\/- 1.5%) for tracking rotor dynamics on shafts with peripheral speeds reaching 2500 m\/s. The physical setup reduces cross-talk suppression issues when probe heads maintain proper center-to-center spacing on target surfaces, preventing electromagnetic field overlap across adjacent sensor channels.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the PR6426\/000-030 probe be connected directly to a PLC analog input module?\u003c\/p\u003e\n\u003cp\u003eA: No, the sensor outputting high-frequency signals must connect to a compatible signal converter, such as the CON 021\/91 or CON 011\/91, which converts the eddy current response into standard voltage or 4-20 mA signals.\u003c\/p\u003e\n\u003cp\u003eQ: What physical installation limits apply to the target shaft diameter?\u003c\/p\u003e\n\u003cp\u003eA: The recommended target shaft diameter is \u0026gt;= 200 mm for optimal performance, though a minimum diameter of 60 mm is required to avoid field distortion and accuracy degradation.\u003c\/p\u003e\n\u003cp\u003eQ: How does the cable length affect system calibration?\u003c\/p\u003e\n\u003cp\u003eA: The probe includes an integral 3 m cable. Because system calibration depends on total circuit inductance and capacitance, extending or altering the cable length without matching converter tuning distorts the 2 V\/mm scale factor.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMount the sensor flange securely using proper torque specifications onto rigid brackets to eliminate mechanical probe resonance under industrial vibration limits (4-5 g at 60 Hz).\u003c\/li\u003e\n\u003cli\u003eRoute the integral sensor cable through dedicated grounded metal conduits, keeping field wiring separated from high-voltage AC motor drives to minimize noise coupling.\u003c\/li\u003e\n\u003cli\u003eMaintain a single-point connection to the main instrument grounding bar for cable shielding, ensuring no ground loops exist between the probe body and signal processing racks.\u003c\/li\u003e\n\u003cli\u003eConfirm that the target shaft material matches the conductive steel calibration standard before finalizing mechanical gap voltage adjustments.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EPRO","offers":[{"title":"Default Title","offer_id":51221903343928,"sku":"PR6426\/000-030","price":256.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0893\/1616\/3896\/files\/256.jpg?v=1788252239","url":"https:\/\/www.automodulexpert.com\/products\/emerson-pr6426-000-030-pr6426-eddy-current-sensor-probe","provider":"AutoModuleXpert Ltd.","version":"1.0","type":"link"}
