  • Sources of vibration excitation The steam turbine

    Vibration excitation can arise from a variety of sources but principally involves the following categories: (a) Nonuniform pressures velocity or changes in the angle of steam flow resulting in a periodic fluctuating force on the rotating blades.

    Excitation Source Accurate measurements depend on a stable regulated and lownoise excitation source voltage. A regulated source is necessary because the output voltage of a strain gage is also proportional to the excitation voltage. Therefore fluctuations in the excitation voltage produce inaccurate output voltages. An ideal data acquisition system provides an excitation source for each

  • Overview of Sensor Signal Paths Tutorial Maxim

    Accurate and stable voltage or current sources with lowtemperature drift are generally used for sensor excitation. The sensor output is ratiometric (usually expressed in mV V) to the excitation source. Consequently the design typically has a common reference for both the analogtodigital converter (ADC) and the excitation circuitry or it uses the excitation voltage as the reference for the
