Ideal for critical rotating machinery such as turbines and compressors, this sensor utilizes electromagnetic induction to track surface variances with micron-level precision. The reverse-mount design is a vital feature for engineers, allowing for external installation and adjustment in confined spaces where traditional front-mount sensors cannot be easily serviced.\u003c\/p\u003e\n\n\u003ch2 id=\"technical-configuration\"\u003eTechnical Configuration\u003c\/h2\u003e\n\u003cp\u003eThis model integrates a robust sensing head with an onboard transmitter that converts displacement data into a standard 4-20mA analog signal. The \"305-000\" configuration is optimized for long-distance signal transmission, minimizing interference over the integrated cable runs of up to 10 meters. This hardware architecture eliminates the need for external proximitor modules in many setups, directly interfacing with PLCs and DCS systems to monitor shaft stability in real-time.\u003c\/p\u003e\n\n\u003ch2 id=\"technical-specifications\"\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0;\"\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth style=\"border: 1px solid #dddddd; padding: 8px; text-align: left;\"\u003eParameter\u003c\/th\u003e\n      \u003cth style=\"border: 1px solid #dddddd; padding: 8px; text-align: left;\"\u003eSpecification\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eMeasurement Range\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e2.0 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eAccuracy (Resolution)\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e±1 µm\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eOutput Signal\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e4 - 20 mA\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eSupply Voltage\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e18 - 30 VDC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eOperating Temperature\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003e-20 to +120 °C\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eMounting Type\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eReverse Mount\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2 id=\"installation-maintenance-guide\"\u003eInstallation \u0026amp; Maintenance Guide\u003c\/h2\u003e\n\u003cp\u003eTo deploy the \u003cstrong\u003ePR9268\/305-000\u003c\/strong\u003e, thread the sensor into the mounting port until the tip reaches the required gap distance from the shaft. Using a multimeter, verify the 4-20mA loop current to ensure the sensor is positioned within its linear range—typically aiming for a 12mA midpoint for neutral displacement. Ensure the mounting area is free of magnetic debris and that the cable is secured with proper strain relief to prevent signal drift caused by mechanical vibration.\u003c\/p\u003e\n\n\u003ch2 id=\"engineering-advantages\"\u003eEngineering Advantages\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003ePR9268\/305-000\u003c\/strong\u003e provides superior thermal stability, maintaining ±1 micron accuracy even as machinery temperatures fluctuate during startup. Its reverse-mount body is specifically designed to withstand the high-pressure environments of steam and gas turbines. By utilizing a current-loop output (4-20mA), this sensor overcomes the voltage drop issues associated with long cable runs, making it the preferred choice for large-scale industrial plants where sensors are located far from the control room.\u003c\/p\u003e\n\n\u003ch2 id=\"technical-faqs\"\u003eTechnical FAQs\u003c\/h2\u003e\n\u003cp\u003eQ1: Does this sensor require an external driver or proximitor?\u003cbr\u003e\nA1: No, the \u003cstrong\u003ePR9268\/305-000\u003c\/strong\u003e is an integrated unit that provides a direct 4-20mA output, simplifying the wiring architecture compared to traditional 3-wire voltage systems.\u003c\/p\u003e\n\u003cp\u003eQ2: Can this sensor be used for water-submerged applications?\u003cbr\u003e\nA2: While the sensor head is highly resistant to oil and moisture, it is rated for industrial atmospheric conditions up to 120 °C. For fully submerged applications, please consult our team for specific sealing requirements.\u003c\/p\u003e\n\u003cp\u003eQ3: How do I troubleshoot a 4mA constant reading?\u003cbr\u003e\nA3: A 4mA reading typically indicates the sensor is at the very beginning of its measuring range or the shaft is too far away. Adjust the mounting depth to bring the target within the 2mm linear window.\u003c\/p\u003e","brand":"Emerson","offers":[{"title":"Default Title","offer_id":51050854285444,"sku":"PR9268\/305-000","price":214.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/PR9268_305-000.jpg?v=1777885222","url":"https:\/\/www.etowonauto.com\/ha\/products\/pr9268-305-000-epro-reverse-mount-eddy-current-sensor","provider":"Etowon Auto","version":"1.0","type":"link"}
