加速度、角速度、速度等物理量不能象测长度一样进行简单测量,为使测量尽可能精确和直接,通常总是借助电路和电路仪表完成这类物理测量,其原理是机械运动通过传感装置改变电路结构,引起电路特征量发生变化,电路特征量的变化又通过电表示数显示,只要加工电路结构,使待测物理量与某电路特征量之间成确定的函数关系,就可从电表直读待测量数值,这就是物理测量中常用的力电转换.
Physical quantities such as acceleration, angular velocity, velocity, etc. can not be measured simply as they are measured. To make the measurement as accurate and direct as possible, this type of physical measurement is usually done by means of circuitry and circuit instrumentation, the principle of which is mechanical movement through the sensing device Structure, causing changes in the characteristics of the circuit, the circuit characteristics of the amount of change and the number of electrical display, as long as the processing circuit structure, the physical quantity to be measured and a circuit between the characteristics of a definite functional relationship, you can direct reading from the meter Measuring values, which is commonly used in physical measurement of power conversion.
