Static characteristics of the sensor
The static characteristics of the sensor are related to the static input signal, the output of the sensor and the input. Since the input and output are independent of time at this time, the relationship between them, that is, the static characteristics of the sensor, can be an algebraic equation without a time variable, or the input amount is used as the abscissa, and the corresponding output is made. The characteristic curve drawn on the ordinate is used to describe. The main parameters characterizing the static characteristics of the sensor are: linearity, sensitivity, resolution and hysteresis.
Sensor dynamics
The so-called dynamic characteristic refers to the characteristic of the output of the sensor when the input changes. In practice, the dynamic characteristics of a sensor are often expressed in terms of its response to certain standard input signals. This is because the sensor's response to a standard input signal is easily experimentally determined, and its relationship to the standard input signal has a certain relationship with its response to any input signal, and it is often known that the former can presume the latter. The most common standard input signals are step signals and sinusoidal signals, so the dynamic characteristics of the sensor are also commonly expressed by step response and frequency response.
