They must also have excellent dynamic response to provide the control system with real-time feedback of rapidly moving components. Camshaft position sensors, or CAM sensors, help adjust engine timing for optimum fuel efficiency and power. The LVDT (see Figure 3.1) is a position-to-electrical sensor whose output is proportional to the position of a movable magnetic core. Position sensors measure either absolute or incremental displacement, and are made with a variety of different materials. plications. 2. Also, when the sensor’s power fails, some retain the measured position data, and other types lose the information. It helps to first think of tilt as the change of direction of the force of gravity (g). A sensor is part of a larger system that contains other detectors, memory devices, data recorders, actuators, signal conditioners and signal processors. The core moves linearly inside a transformer consisting of a center primary coil and two outer secondary coils wound on a cylindrical form. Allow, together with appropriate velocity information, to integrate movement to a position estimate.
