It is engineered to provide continuous, high-accuracy measurement of axial shaft displacement, commonly referred to as thrust position, in critical rotating equipment such as large compressors, steam turbines, and gas turbines. By monitoring the relative position between the shaft and the thrust bearing, the module serves as a primary defense against catastrophic mechanical failure caused by bearing wear or excessive axial movement.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eContinuously monitors axial displacement with high-speed response times.\u003c\/li\u003e\n\u003cli\u003eProvides integrated Alert and Danger alarm logic for automated machine protection.\u003c\/li\u003e\n\u003cli\u003eIncludes proportional 4-20 mA outputs for integration with external DCS or PLC systems.\u003c\/li\u003e\n\u003cli\u003eFront-panel LED indicators provide real-time status updates for OK, Bypass, Alert, and Danger conditions.\u003c\/li\u003e\n\u003cli\u003eCompatible with standard Bently Nevada proximity probe (Proximitor) sensor inputs.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOrdering Information\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel Component\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eConfiguration\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e3300\/20\u003c\/td\u003e\n\u003ctd\u003eAxial Position Monitor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eXX\u003c\/td\u003e\n\u003ctd\u003eMeasurement Range Option\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e03\u003c\/td\u003e\n\u003ctd\u003eAgency Approval Option\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e01\u003c\/td\u003e\n\u003ctd\u003eProximity Probe Input\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e00\u003c\/td\u003e\n\u003ctd\u003eStandard Relay Outputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e00\u003c\/td\u003e\n\u003ctd\u003eStandard Input Barrier\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\u003e-30 degC to +65 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTypical Power Consumption\u003c\/td\u003e\n\u003ctd\u003e2 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Compatibility\u003c\/td\u003e\n\u003ctd\u003eProximitor sensor signals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Signals\u003c\/td\u003e\n\u003ctd\u003eDynamic position, 4-20 mA, Relay\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 monitor module to prevent electrical damage.\u003c\/li\u003e\n\u003cli\u003eVerify that all proximity probe wiring is correctly shielded and routed away from high-voltage AC cables to minimize EMI interference.\u003c\/li\u003e\n\u003cli\u003eHandle the module using proper ESD precautions to protect internal circuitry.\u003c\/li\u003e\n\u003cli\u003eEnsure the module is fully seated in the rack slot and that the front-panel locking mechanisms are engaged.\u003c\/li\u003e\n\u003cli\u003eCheck that the configuration jumpers and software setpoints match the specific machine requirements before commissioning.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch3\u003eWhat is the primary function of the 3300\/20 module?\u003c\/h3\u003e\u003cp\u003eThe 3300\/20 is designed to monitor the axial position of a machine shaft relative to its thrust bearing, providing critical data to detect bearing wear or shaft drift before damage occurs.\u003c\/p\u003e\u003ch3\u003eDoes this module include intrinsic safety barriers?\u003c\/h3\u003e\u003cp\u003eThe 00 suffix in the barrier position indicates this configuration does not include internal intrinsic safety barriers.
