Equivalent Circuit of Vibration Meter Input
(3) Referring to Figure 2 and the preceding formula, if E is known to be
9.0 millivolts per degree per second and R1 is known to be 700 ohms, using the
equation for corrected sensitivity
gives the following sample calculation:
(4) When the manufacturer's specifications do not give the open circuit
voltage but state the voltage across some resistive load other than 10 kilohms, you
can calculate the corrected sensitivity as follows:
Designate E3 as the voltage known.
Designate R3 as the resistive load known.
Calculate E1, the corrected sensitivity.
With E3 known to be 105 millivolts per inch per second R3 to be 150
kilohms, and E1 to be 750 ohms, the following sample calculation is given:
