WIDTH MEASUREMENT: Sensor WIDTH MEASUREMENT: Sensor measures the distance between itself measures the distance between itself and the box (one measures distance A and the box (one measures distance A and the other, distance B). This and the other, distance B). This information is transmitted to a PLC, information is transmitted to a PLC, which calculates the width W by which calculates the width W by subtracting A and B from the total subtracting A and B from the total distance between the sensors.distance between the sensors.
