Four strain gauges, with specification given below, are available to measure the torque on a cylindrical shaft 4 cm in diameter connecting a motor and load. (a) Draw clearly labelled….
What is the minimum response time required by the sensor?
The output of an analog ultrasonic sensor that produces 4 to 20 mA of current will be mA when the target is located halfway between the minimum and the maximum calibrated sensing distance. Calculate the values of the resistor and the capacitor in a snubber circuit when the voltage across the contacts is 200 volts and the holding current is 100 mA. Suppose the diameter of a target is 2 inches, the light beam width is 1⁄2 inch, and the speed of the object is 5 inches per second. What is the minimum response time required by the sensor?
