By monitoring shaft displacement during slow-roll operation, this module detects rotor bow and potential misalignment issues before they escalate into mechanical failure. It integrates seamlessly into the 3300 Monitoring System, providing real-time data for predictive maintenance and operational safety.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDesigned for continuous monitoring of peak-to-peak eccentricity.\u003c\/li\u003e\n\u003cli\u003eAccepts inputs from standard proximity probe systems via Proximitor sensors.\u003c\/li\u003e\n\u003cli\u003eProvides dedicated Alert and Danger alarm setpoints for automated machine protection.\u003c\/li\u003e\n\u003cli\u003eIncludes front-panel LED indicators for system status, including OK, Bypass, Alert, and Danger conditions.\u003c\/li\u003e\n\u003cli\u003eConfigurable sensitivity settings to accommodate various probe types.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOrdering Information\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e3300\/40-12-01-01-00-00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement\u003c\/td\u003e\n\u003ctd\u003eEccentricity (Slow-roll\/Shaft bow)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAgency Approval\u003c\/td\u003e\n\u003ctd\u003eStandard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTransducer Input\u003c\/td\u003e\n\u003ctd\u003eProximity Probe\/Proximitor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelay Output\u003c\/td\u003e\n\u003ctd\u003eStandard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBarrier Option\u003c\/td\u003e\n\u003ctd\u003eStandard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRange\u003c\/td\u003e\n\u003ctd\u003eDefault\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 60 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e1.5 W (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensitivity\u003c\/td\u003e\n\u003ctd\u003eUser-programmable (200 mV\/mil or 100 mV\/mil)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Accuracy\u003c\/td\u003e\n\u003ctd\u003e±0.33% typical (±1% max at 25 degC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Outputs\u003c\/td\u003e\n\u003ctd\u003e+4 to +20 mA, +1 to +5 VDC, 0 to -10 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the 3300 rack is powered down before inserting or removing the module to prevent electrical damage.\u003c\/li\u003e\n\u003cli\u003eThe module must be seated firmly in the rack slot to ensure proper backplane connection.\u003c\/li\u003e\n\u003cli\u003eUse shielded cabling for all transducer inputs to minimize electromagnetic interference (EMI).\u003c\/li\u003e\n\u003cli\u003eMaintain adequate ventilation around the 3300 rack to keep ambient temperatures within the 0 to 60 degC specification.\u003c\/li\u003e\n\u003cli\u003eVerify that all proximity probe wiring is routed away from high-voltage power lines.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the primary function of the 3300\/40 module?\u003c\/h3\u003e\u003cp\u003eThe 3300\/40 is designed to monitor shaft eccentricity, which is the displacement of the shaft centerline during slow-roll conditions.
