Question

Once the signal goes into the box, it passes through a pre-amp, which will change it. Look on the pre-amp or in the table in the appendix; by what factor will it change the signal? Double it? Cut it in half? Multiply by five? Some other value? When the signal comes out of the pre- amp, what voltage will correspond to one kilopascal of pressure? .Given the signal that comes out of the pre-amp, what gain factor do you need to multiply so that one kilopascal (or another pressure unit you chose to use) corresponds to a value of one in Lab Assistant?

Explanation / Answer

The range of the CI-6534A Low Pressure Sensor is between 0 and 10 kiloPascals. The output voltage from the sensor is +1.00 Volts when the pressure is 1 kiloPascal (kPa), and the output voltage is linear[double it, cut it by half or multiply by 5 the input, the same convesrion factor should be corrected at output]. The resolution of the sensor is 0.005 kiloPascals . Therefore, the output voltage should be +10.00 Volts at the top of the range (10 kPa).
