A moving-coil meter movement has a meter resistance rM = 200 ? , and full-scale deflection is caused by a meter current im = 10?A. The meter is to be used to display pressure, as measured by a sensor, up to a maximum of 100 kPa. Models of the meter and pressure sensor are shown in Figure P2.71 along with the relationship between measured pressure and the sensor output vT .
a. Devise a circuit that will produce the desired behavior of the meter, showing all appropriate connections between the terminals of the sensor and the meter.
b. Determine the value of each component in the circuit.
c. What is the linear range, that is, the minimum and maximum pressure that can accurately be measured?
