A pressure-measurement system uses a sensor that converts pressure into voltage according to the transfer functions, Vp = .5â p . This voltage is then converted into a current. As pressure varies from 0 to 100 psi, the current varies from 4 to 20 mA. a. Find the transfer function equation for the conversion of voltage to current. b. What pressure change, Î

Unformatted text preview: p, will cause the current to change by 1 mA from 19 mA to 20 mA. c. What pressure change, &Icirc; p, will cause the current to change by 1 mA from 4 mA to 5 mA? Why is the pressure change not the same as in the previous case, even though the current changed by 1 mA in both cases? d. Is the relationship of current versus pressure linear or nonlinear?...
