It works with non-contact eddy current probe systems to capture micro-inch shaft displacement, translating it into a linear 4-20 mA analog loop signal. Featuring country-specific CN agency certification, this unit integrates directly into standard DCS, PLC, or SCADA frameworks without intermediate monitor racks, protecting capital assets like turbines and compressors from catastrophic thrust failures.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Configuration\u003c\/h2\u003e\n\u003ch3\u003eCore Technical Advantages\u003c\/h3\u003e\n\u003cp\u003eThe 991-01-XX-01-CN transmitter integrates local Proximitor signal conditioning networks into a single space-saving housing, minimizing enclosure footprints and field cabling runs. Its heavy-duty circuitry features a quick response time to capture sudden step changes in axial displacement immediately. The rugged IP65-rated housing provides excellent ingress protection against dust and moisture, while the 35 mm DIN rail design and standard 24V DC loop-power interface streamline high-density panel integration.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin-top: 15px;\"\u003e\n  \u003ctbody\u003e\n    \u003ctr style=\"background-color: #f2f7fc;\"\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; font-weight: bold; padding: 10px; width: 35%;\"\u003eModel Designation\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; padding: 10px;\"\u003e991-01-XX-01-CN\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; font-weight: bold; padding: 10px;\"\u003eMeasurement Configuration\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; padding: 10px;\"\u003eThrust \/ Axial Position \/ Displacement\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f2f7fc;\"\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; font-weight: bold; padding: 10px;\"\u003eFull-Scale Range\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; padding: 10px;\"\u003e0.1 - 0 - 0.1 mm (symmetric axial displacement)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; font-weight: bold; padding: 10px;\"\u003ePrimary Analog Output\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; padding: 10px;\"\u003eStandard 4-20 mA current loop\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f2f7fc;\"\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; font-weight: bold; padding: 10px;\"\u003ePower Supply Requirement\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; padding: 10px;\"\u003e24 VDC (loop powered)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; font-weight: bold; padding: 10px;\"\u003eFrequency Response\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; padding: 10px;\"\u003eUp to 300 Hz\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f2f7fc;\"\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; font-weight: bold; padding: 10px;\"\u003eIngress Protection Rating\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; padding: 10px;\"\u003eIP65\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; font-weight: bold; padding: 10px;\"\u003eAgency Approvals\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; padding: 10px;\"\u003eCN (Country Specific certified\/Ex-compliant variants)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f2f7fc;\"\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; font-weight: bold; padding: 10px;\"\u003eMounting Base\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; padding: 10px;\"\u003e35 mm standard DIN rail clips\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; font-weight: bold; padding: 10px;\"\u003eNet Weight\u003c\/td\u003e\n      \u003ctd style=\"border: 1px solid #a9bccc; padding: 10px;\"\u003e0.43 kg\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eInstallation Guide\u003c\/h2\u003e\n\u003ch3\u003eMechanical Mounting and Clearance\u003c\/h3\u003e\n\u003cp\u003eSnap the transmitter securely onto a clean 35 mm DIN rail within a local protective panel enclosure.
