Question

tied vdel Plpsil ADCort 12. For a differential pressure transducer you collect the static calibration data in the table with a data acquisition system that has a 10 bit analog to digital converter (ADC) and voltage input range of 0-5 volts10 Write down the calibration function needed to display the pressure in a LabVIEW indicator 2.2 2. 12 (S pt) a. Ans/ (2 pt) b. What is the counts to volts conversion factor? And In the table write down the ADC count you would expect for each measurement. Ans/ (3 pt) c.With this system would you be able to monitor a system pressure of 50 Psi? Explain. Ans/

Explanation / Answer

Answer:

a. Calibration function to display pressure: (Cfs/Vex)*(Vmeas/CF)

where,

Cfs = Full capacity - maximum pressure received by transducer

Ves = Excitation voltage - recommended input voltage

Vmeas = Measured voltage - raw voltage from the sensor

CF = Calibration factor - output of transducer

b. ADC input voltage and output code are related as :

Vin = (Output code)*(LSB size)

LSB size = FSR/2^n

where, FSR = full-scale input range of ADC

n = no. of bits in ADC output code

2^n = total no. of ADC codes

c. Yes, we would be able to monitor a system pressure of 50 psi with this system.
