Channel 1 operates with eddy current sensors and channel 2 with seismic or piezoelectric sensors. Each measuring channel can operate separately or the results of both channels may be used to calculate the difference. By means of calculating the difference of these signals, the absolute shaft vibration results. At the MMS 6140 monitor the relative shaft vibration is measured with an eddy current sensor and the absolute bearing vibration with a seismic or piezo-electric sensor. The phase shift between the signals, caused by the different measuring principles, is compensated by the electronics. In the following, the bearing vibration signal is subtracted from the shaft vibration signal. The time signal arising thereof is then processed like a normal vibration signal, converted to a characteristically value according to the configuration parameters, output as current signal and supervised on limit exceedings.\u003c\/p\u003e\n\u003cp\u003eThe measurement of absolute shaft vibrations serves the construction of turbine protection systems. They provide signals for analysis and diagnosis systems to be further processed in field bus systems and networks. Such cards of the MMS 6000 family are suitable to build up systems for increasing performance, efficiency and safety of operation and to extend the machines' life times. Application fields of the epro measuring amplifiers are steam, gas and water turbines, compressors, fans, centrifuges and other turbo machinery.\u003c\/p\u003e\n\u003ch3\u003e\n\u003cstrong\u003eTechnical Data:\u003c\/strong\u003e\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\nOpen circuit and closed circuit mode\n\u003c\/li\u003e\n\u003cli\u003e\nChannel or module inhibit\n\u003c\/li\u003e\n\u003cli\u003e\nMeasuring range multiplier to modify the alarm limits during run-up or run-down; adjustable within 1.000 to 4.999; 24 V logic.\n\u003c\/li\u003e\n\u003cli\u003e\nInput resistance: ≥ 30 kΩ\n\u003c\/li\u003e\n\u003cli\u003e\nKey pulse input: 1 pulse per revolution for analysis purposes of the system: 24 V Logic\n\u003c\/li\u003e\n\u003cli\u003e\nInput resistance: \u0026gt; 30 kΩ\n\u003c\/li\u003e\n\u003cli\u003e\nPulse duration: min. 10µs (edge-triggered)\n\u003c\/li\u003e\n\u003cli\u003e\nVoltage inputs: 0…10 V; (Two, one for each channel)\n\u003c\/li\u003e\n\u003cli\u003e\nInput impedance: \u0026gt; 100 kΩ\n\u003c\/li\u003e\n\u003cli\u003e\nResolution: 10 bit\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\n\u003cstrong\u003eSensor Inputs:\u003c\/strong\u003e\n\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\nTwo independent sensor inputs.
