n the packaging industry, assume that a strain gauge sensor is used to measure the weight of a food package. The strain gauge changes its output DC voltage value whenever some force/weight is applied on it. The food packs weigh between 0.5LB and 15LB. The sensor is calibrated in such a way that it outputs 0V at 1LB applied force/weight. After the calibration, the sensor transfer function is given as 100mv/0.5LB. What is the sensor output DC voltage value if the measured weight is 3 LB? A. 0.2V B. -0.2V C. 0.4V D. -0.4V In the above question, assume that the sensor can measure from 0LB to 21 LB with an accuracy of Full-scale error.
