Acceleration Transducers : One of the method is to use strain guage along with a opamp differentiator to measure acceleration . ( strain guage and opamp differentiator already discussed in class) Differentiating displacement twice gives you acceleration Strain gauge acceleration transducers convert the acceleration of running vehicle or the vibration of car body or machinery into minute voltage to enable accurate measurement of acceleration or vibration with various measuring instruments. Each model is compact and lightweight, and ensures superior static and dynamic characteristics. Various rated capacities cover a wide scope of applications. In addition, triaxial models are available for simultaneous detection of accelerations in three directions: X, Y and Z. Features Compact and lightweight design results in minimal effects on the vibration mode of the measuring objects to which the transducer is mounted. Wide frequency response range enables faithful detection of impact-initiated acceleration. Fatigue life is 10 million times or more. Principle of Acceleration Transducers With the basic configuration shown below, acceleration initiates inertia force to the weight and deforms the leaf spring The strain gauge adhered to the leaf spring detects the displacement of the leaf spring as a strain quantity proportional to the acceleration. The strain gauge signal is amplified to enable acceleration measurement

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
