It conditions raw proximity probe signals into a linear, proportional 4-20 mA current loop that represents total radial vibration or shaft dynamic displacement.\u003c\/p\u003e\n\u003cp\u003eThis transmitter interfaces directly with a non-contacting eddy current probe system, executing signal conversion locally without the requirement of an intermediate machinery monitoring rack. The hardware manages the high-frequency probe drive and demodulates the return signal to extract peak-to-peak displacement trends. It maintains full architectural compatibility with specific proximity transducers and calibrated extension cables to deliver accurate, stable scale factors under varying industrial conditions.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStandard 4-20 mA current loop output proportional to peak-to-peak machinery vibration\u003c\/li\u003e\n\u003cli\u003eDirect interface capability with 3300 NSv proximity probe systems\u003c\/li\u003e\n\u003cli\u003eIntegrated signal conditioning electronics contained in a rugged, field-mountable housing\u003c\/li\u003e\n\u003cli\u003e35 mm DIN rail mounting hardware for high-density control cabinet installations\u003c\/li\u003e\n\u003cli\u003eWide input voltage tolerance to accommodate industrial loop resistance variations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRadial shaft vibration monitoring on high-speed pumps and centrifugal compressors\u003c\/li\u003e\n\u003cli\u003eStructural and bearing housing vibration tracking on industrial fans and blowers\u003c\/li\u003e\n\u003cli\u003eElectric motor, generator, and auxiliary rotating machinery protection loops\u003c\/li\u003e\n\u003cli\u003eBalance-of-plant equipment integration into standard factory control systems\u003c\/li\u003e\n\u003cli\u003ePredictive maintenance loop logging in petrochemical, oil, gas, and power facilities\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eModel Option Block\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eConfiguration Specification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e05\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFull-scale Option: 0-5 mils pp (0-125 um pp)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e70\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSystem Length Option: 7.0 metres (23.0 feet)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e01\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMounting Option: 35 mm DIN rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e05\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAgency Approval Option: CSA, ATEX, IECEx intrinsically safe \u0026amp;
