It integrates two distinct measurement channels: Channel 1 for eddy current sensors to capture relative shaft vibration and Channel 2 for seismic or piezoelectric sensors to monitor absolute bearing vibration. By calculating the differential signal between these channels, the monitor derives absolute shaft vibration, providing critical data for turbine protection and predictive maintenance systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eDual independent channels for versatile transducer compatibility\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eDifferential calculation for absolute shaft vibration measurement\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003ePhase shift compensation for accurate signal processing\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eConfigurable outputs for alarm, analysis, and fieldbus integration\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eContinuous diagnostics for sensor integrity and signal supervision\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eModel:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eMMS6140\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eManufacturer:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eEmerson (Epro MMS6000 Series)\u003cbr\u003e\u003cstrong\u003eProduct Type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eDual Channel Vibration Monitor\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMeasurement Inputs:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eTwo independent channels:\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eChannel 1: Eddy current sensors for shaft vibration\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eChannel 2: Seismic or piezoelectric sensors for bearing vibration\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli\u003e\n\u003cp\u003eDifferential, galvanically isolated inputs\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eOpen- and short-circuit proof\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eInput Signal Characteristics:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChannel 1 (Eddy Current):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eInput impedance: ≥ 100 kΩ\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eVoltage range: -1…-23 V\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSignal frequency range: 1\/5…50…2000 Hz\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSignal amplitude: 0–400 mVpp minimum, 0–2000 mVpp maximum\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eIndividual sensor supply: -26.7 V, 20–35 mA\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eChannel 2 (Seismic\/Piezoelectric):\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eInput impedance: ≥ 100 kΩ\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eVoltage range: -5…+15 V\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSignal frequency range: 5\/10…50…1000\/1600 Hz (VDI 2056 \/ DIN 45666 \/ ISO 3945)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSignal amplitude: 311–9500 mVpp, configurable\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSensor supply: 0–8 mA programmable, galvanically isolated\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eAccuracy: ±0.5% of full scale or set value\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eControl \u0026amp;
