Question

accelerometer can be used for different applications. The type of application is closely An related to the range, natural frequecy and damping characteristies of the accelerometers. difference is in the method of mass displacement mesurement. T iples that can be used for designing an accelerometer The here are several . Explain clearly the working principle of those transducer accelerometer below that is used to measure any motion or displacement. i) LVDT (Linear Variable Differential Transformer) ii) Variable Reluctance iii) Piezoelectric b. The reading for an accelerometer is V 1.427 mVims2. Based on Figure Q3b below: Ri R2 Va FIGURE Q3b i) Calculate the system Gain and inverting resistor ratio if the output signal is a i) Find the value of Ry and C if the signal output is a displacement of V, 0.2 [PO2-12 marks) velocity V, 0.3 V/ms V/mm
