Pressure sensor output signal selection
YD series pressure sensors are widely used in a wide range of industries, especially in the metallurgical industry, automotive industry, power equipment, chemical engineering, engineering machinery, paper industry, shipbuilding industry and machine tool manufacturing.
According to the pressure sensor pressure signal form:
(1) Analog: The sensor output is an analog voltage;
(2) Digital: The sensor output is digital, such as: encoder sensor.
The static characteristics of the sensor are related to the static input signal, the output of the sensor and the input. Because the input and output are independent of 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 can be used as the abscissa, and the corresponding output is 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.
The so-called dynamic characteristic refers to the characteristic of the output of the pressure sensor when the input changes. In practice, the dynamic characteristics of the sensor are often represented by its response to certain standard input signals. This is because the response of the sensor to the standard input signal is easily experimentally determined, and its response 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.
