It conditions signals from proximity probes to output a proportional 4-20 mA current loop, representing total radial vibration or axial thrust measurement.\u003c\/p\u003e\n\u003cp\u003eThis transmitter interfaces directly with a non-contacting eddy current probe system to log dynamic shaft displacement. The hardware conversion architecture extracts the peak-to-peak or static position trends without requiring an intermediate machinery monitoring rack, making it suitable for standard control loops. It maintains full system compatibility with specific proximity probe sub-assemblies and calibrated cable lengths to ensure accurate scale-factor linear output.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStandard 4-20 mA current loop output proportional to machinery vibration\u003c\/li\u003e\n\u003cli\u003eDirect interface capability with 3300 NSv proximity probe systems\u003c\/li\u003e\n\u003cli\u003eIntegrated signal conditioning inside a compact, field-mountable enclosure\u003c\/li\u003e\n\u003cli\u003eBulkhead screw mounting hardware for rigid installation on machine housings\u003c\/li\u003e\n\u003cli\u003eWide input voltage range to accommodate varying loop load requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRadial vibration monitoring on small centrifugal pumps and compressors\u003c\/li\u003e\n\u003cli\u003eAxial shaft displacement measurements on industrial fans and blowers\u003c\/li\u003e\n\u003cli\u003eElectric motor and generator bearing housing vibration tracking\u003c\/li\u003e\n\u003cli\u003eAuxiliary rotating machinery protection loops in petrochemical facilities\u003c\/li\u003e\n\u003cli\u003eBalance-of-plant equipment integration into factory control architectures\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\u003e50\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSystem Length Option: 5.0 metres (16.4 feet)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e02\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMounting Option: Bulkhead screws\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003e00\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAgency Approval Option: Not required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eTechnical 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\u003eValue\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eBently Nevada\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct No.\u003c\/td\u003e\n\u003ctd\u003e990-05-50-02-00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003e990 Vibration Transmitter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eU.S.A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFull-scale Option\u003c\/td\u003e\n\u003ctd\u003e0-5 mils pp (0-125 um pp)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Length\u003c\/td\u003e\n\u003ctd\u003e5.0 metres (16.4 feet)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput\u003c\/td\u003e\n\u003ctd\u003eAccepts 1 non-contacting 3300 NSv Proximity Probe and extension cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower\u003c\/td\u003e\n\u003ctd\u003e+12 to +35 Vdc input at the transmitter terminal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-35 Celsius to +85 Celsius (-31 Fahrenheit to +185 Fahrenheit)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-51 Celsius to +100 Celsius (-60 Fahrenheit to +212 Fahrenheit)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e1.5 Kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Configuration:\u003c\/strong\u003e Mount the transmitter base securely onto a flat bulkhead surface using the pre-selected bulkhead screw hardware option.
