Capacitive transducers are normally employed for both static and dynamic measurements.
A static measurement is a measurement of a quantity that does not change over time. For example, a capacitive transducer can be used to measure the level of a liquid in a tank. The level of the liquid will not change very much over time, so a capacitive transducer is a good choice for this type of measurement.
A dynamic measurement is a measurement of a quantity that changes over time. For example, a capacitive transducer can be used to measure the speed of a moving object. The speed of the object will change over time, so a capacitive transducer is a good choice for this type of measurement.
Capacitive transducers work by measuring the change in capacitance between two plates. The capacitance between two plates is proportional to the area of the plates and the distance between them. When the distance between the plates changes, the capacitance changes. This change in capacitance can be used to measure a variety of quantities, including level, speed, and position.
Capacitive transducers are a versatile type of transducer that can be used for a variety of measurements. They are relatively inexpensive and easy to use. They are also non-contact, which means they can be used to measure quantities without touching the object being measured.
