Instrumentation quick question - nonlinearity error

AI Thread Summary
The discussion revolves around calculating the nonlinearity error of a non-linear pressure sensor with a specified input and output range. The output voltage at 4 bar is given as 2.2V, while the expected output based on a linear model is 2V. The difference of 0.2V is noted, and participants are prompted to determine this difference as a percentage of the full scale. The conversation emphasizes the need to express the nonlinearity error in terms of percentage relative to the sensor's full scale. The calculation of this percentage is crucial for understanding the sensor's performance.

Homework Statement


A non-linear oressure sensor has an input range of 0 to 10 bar and an output range of 0 to 5V. The output voltage at 4 bar is 2.2V. The nonlinearity as a percentage of psan is?

Homework Equations


none


The Attempt at a Solution



Drew a straight line using the data given with equation y=1/2x. (0-10 on x-axis;0-5v on y-axis). Therefore at x=4, y=2. 2.2-2=0.2?

Looks good so far. So what is that as a percentage of full scale?
