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.
Absolute pressure sensor; This sensor measures the pressure relative to perfect vacuum. Gauge pressure sensor; This sensor measures the pressure relative to atmospheric pressure. A tire pressure gauge is an example of gauge pressure measurement; when it indicates zero, then the pressure it is measuring is the same as the ambient pressure. Vacuum pressure sensor; This term can cause confusion.
