  HYDAC贺德克传感器的静态特性是指对静态的输入信号,HYDAC传感器的输出量与输入量之间所具有相互关系。因为这时输入量和输出量都和时间无关,所以它们之间的关系,即传感器的静态特性可用一个不含时间变量的代数方程,或以输入量作横坐标,把与其对应的输出量作纵坐标而画出的特性曲线来描述。表征传感器静态特性的主要参数有:线性度、灵敏度、迟滞、重复性、漂移等。

1、线性度:指传感器输出量与输入量之间的实际关系曲线偏离拟合直线的程度。定义为在全量程范围内实际特性曲线与拟合直线之间的zui大偏差值与满量程输出值之比。
2、灵敏度:灵敏度是传感器静态特性的一个重要指标。其定义为输出量的增量与引起该增量的相应输入量增量之比。用S表示灵敏度。
3、迟滞:传感器在输入量由小到大(正行程)及输入量由大到小(反行程)变化期间其输入输出特性曲线不重合的现象成为迟滞。对于同一大小的输入信号,传感器的正反行程输出信号大小不相等,这个差值称为迟滞差值。
4、重复性:重复性是指传感器在输入量按同一方向作全量程连续多次变化时,所得特性曲线不*的程度。
5、漂移:传感器的漂移是指在输入量不变的情况下,传感器输出量随着时间变化,此现象称为漂移。产生漂移的原因有两个方面:一是传感器自身结构参数;二是周围环境(如温度、湿度等)。
6、分辨力:当传感器的输入从非零值缓慢增加时,在超过某一增量后输出发生可观测的变化,这个输入增量称传感器的分辨力,即zui小输入增量。
7、阈值:当传感器的输入从零值开始缓慢增加时,在达到某一值后输出发生可观测的变化,这个输入值称传感器的阈值电压。

hydac Germany HYDAC sensor principle and application of the dynamic characteristics of the sensor HYDAC Germany
The so-called dynamic characteristics, when the input means is changed, it is characteristic of the sensor output. In practice, the dynamic characteristics of the sensor HYDAC its response to some common standard input signal to represent. This is because the sensor's response to the standard input signal is easily determined experimentally, and in response to its standard input signal the presence of a certain relationship between its response to any input signal, often can be presumed to know the former to the latter. The most commonly used standard input signal and sine signal two kinds of step signal, so the dynamic characteristics of the sensor is also used HYDAC step response and frequency response is represented.
Linearity Germany HYDAC HYDAC sensors
Under normal circumstances, the actual output of the sensor is static characteristic curves rather than straight lines. In practice, the instrument has a uniform scale readings, commonly fit a straight line approximation to represent the actual characteristic curve linearity (nonlinear error) is the degree of approximation of a performance. Fitting a straight line to select a variety of methods. As the theory of linear zero input and full scale output points connected as fitting a straight line; or the square of the deviation of each point on the curve and the smallest theoretical straight line as fitting a straight line, this is called the linear least squares fitting quasi co-linear.
