5.2.1传感器的定义
· 国家标准GB7665-87X寸传感器下的定义是: “能感受规定的被测量并按照一定的规律转换成可用信号的器件或装置, 通常由敏感元件和转换元件组成
'
。
· 本书定义:将被测非电量信号转换为与之有确定对应关系电量输出的器件或装置叫做传感器,也叫变换器、 换能器或探测器。
. 传感器是一种检测装置,能感受到被测晕的信息,并能将检测感受到的信息, 按一定规律变换成为电信号或其他所需形式的信帜俞出,以满足信息的传输、 处理、 存储、 显示、 记录和控制等要求。 被测量的信息可以是光、 热、 运动、 湿气压力, 或许多其他环境现象中的任何一种。
. 举例:麦克风、 加速度计、 磁力计 、 温度计、 还有哪些常见的传感器
