Description: 具有桥式结构的传感器很多，如利用应变原理、磁电阻原理和其他变电阻原理的传感器，可以实现对压力、位移、加速度、磁场等物理量的测试。这种结构的差分输出可以增加灵敏度，也有一定抵消外加干扰的能力。而且有的虽不是差分输出，比如电阻分压式的输出，可以认为是“半桥”，我们还可以人为的加上另一半，即加上一对精密电阻和一个电位器组成另一个分压电路，形成差分输出。每次调节电位器使差分输出为0，抵消零磁电压。-Bridge structure with many sensors, such as the use of contingency theory, the principle of magneto-resistance and other variable resistance sensor principle can be achieved on the pressure, displacement, acceleration, magnetic field, such as physical tests. The structure of the differential output can increase sensitivity, but also have some ability to offset the additional interference. And some is not a differential output, such as pressure resistance of the output type, you can think is Platform: |

Description: 光电编码器，是一种通过光电转换将输出轴上的机械几何位移量转换成脉冲或数字量的传感器。
这是目前应用最多的传感器，光电编码器是由光栅盘和光电检测装置组成。光栅盘是在一定直径的圆板上等分地开通若干个长方形孔。由于光电码盘与电动机同轴，电动机旋转时，光栅盘与电动机同速旋转，经发光二极管等电子元件组成的检测装置检测输出若干脉冲信号-Photoelectric encoder, a photoelectric conversion to the output shaft of the mechanical geometry of displacement into a pulse or digital sensors. This is currently the most widely used sensors, optical encoder is determined by the grating disk and photoelectric detection device component. Grating disc is a circular plate in such a diameter of several rectangular holes partially opened. Because coaxial photoelectric encoder and the motor, the motor rotates, the grating disk rotates with the same speed motor, the light-emitting diodes and other electronic components of the detection device detects certain pulse signal output Platform: |

Description: A/D转换器是用来通过一定的电路将模拟量转变为数字量。
模拟量可以是电压、电流等电信号，也可以是压力、温度、湿度、位移、声音等非电信号。但在A/D转换前，输入到A/D转换器的输入信号必须经各种传感器把各种物理量转换成电压信号。-A/D converter is used by certain circuit analog into digital quantity.
The analog voltage, current can be other signals, also can be pressure, temperature, humidity, displacement, sound and other non electrical signal. But before A/D transition, input signal to the A/D converter must be approved by the various sensors to various physical quantity into voltage signal. Platform: |
