The specification of a pressure sensor is shown below: Range ofmeasurement: 10 psi to 250 psi. Accuracy : ±0.2% of span. Transferfunction : 0.5?/psi. Transfer function accuracy: ±0.1% Sensoroutput resistance, R : 2k? - 20k?. Sensor time constant: 200 ms
. The resistance is then converted to a voltage with thetransfer function:
V= 10R/R+1000
1/Determine the uncertainty for measurement of 120psi. What isthe possible pressure?
2/Determine the possible range of the transfer function.Interpret the possible range that you have determine.
3/Determine the linear relationship between resistance andpressure. Draw a graph and explain briefly why it should be linearrelationship.
4/Determine the pressure result from a resistance of 10 k?.
5/At t = 0 s, the pressure change suddenly from 12 psi to 120psi. Determine the voltage output and its pressure at 0.24 s. Atwhat time the output reach 0.3V?
