执行器
现场的传感器(Sensor)与执行器(Actuator)又称为现场终 端,传感器(包括变送器)是用来对物理量(如温度、湿度、压 力、压差、位移、速度、电压、电流以及化学物质的浓度...
执行机构
...体沿阀杆泄漏,起密封作用的各零件组合, 包括填料压板,填料压盖,填料,填料垫, 填料弹簧,密封环等 执行机构 ( Actuator ):将控制信号转换成相 应的动作以控制阀内件的位置或其他调节机 构的位置,信号或驱动力可为气动、电动、 液动。
致动器
光学读取头的致动器(Actuator)是光驱组件中精密定位组件,文章结合生产实际验证了改变四弦型致动器MCK模型中的要素对致动器动态特性的影响。
An actuator is a type of motor that is responsible for moving or controlling a mechanism or system.It is operated by a source of energy, typically electric current, hydraulic fluid pressure, or pneumatic pressure, and converts that energy into motion. An actuator is the mechanism by which a control system acts upon an environment. The control system can be simple (a fixed mechanical or electronic system), software-based (e.g. a printer driver, robot control system), a human, or any other input.
