The vibrating wire sensors are very robust and have a high sensitivity, they are widely used in civil construction for monitoring structures, and hence an accurate measurement of these instruments is highly recommended. However, these sensors must be stimulated before being measure, and then it will transmit a response signal. Thus this study aims to compare the different methods that can be used for excitation to this type of sensor to indicate what their differences and characteristics, consequently proposing one that provides a better response signal.
Keywords: Electromechanical sensors, signal processing, measurement, frequency response, electrical stimu-lation, vibrating wire.
