Let's begin with monarchy. Monarchy was the most common form of government until the 19th century. Monarchy is a form of government in which a single family rules from generation to generation. The power, or sovereignty, is personified in a single individual.
Uses of this type of sensor in the automotive industry include piezoelectric accelerometers, piezoelectric force sensors, and piezoelectric pressure sensors. FIGURE. Piezoelectric sensor circuit. The sensor is a voltage generator and has a resistor connected in series with it.
Often pressure can be converted to some intermediate form, such as displacement. The sensor then converts this displacement into an electrical output such as voltage or current. The three most universal types of pressure transducers of this form are the strain gage, variable capacitance, and piezoelectric.
