AS-Interface. Actuator Sensor Interface ( AS-Interface or ASi) is an industrial networking solution (physical layer, data access method and protocol) used in PLC, DCS and PC-based automation systems. It is designed for connecting simple field I/O devices (e.g. binary ON/OFF devices such as actuators, sensors, rotary encoders, analog inputs and ...
Valve actuator. Electric actuator (blue cylinder) on a valve in a power plant. A black handwheel is visible on the actuator, which allows manual positioning of the valve. The blue valve body is visible in-line with the pipe. The valve actuator opens or closes the butterfly disc of the valve based on electrical signals sent to the actuator.
DVD drive with leadscrew and stepper motor. Floppy disc drive with leadscrew and stepper motor. A linear actuator is an actuator that creates linear motion (i.e., in a straight line), in contrast to the circular motion of a conventional electric motor. Linear actuators are used in machine tools and industrial machinery, in computer peripherals ...
Actuator. An actuator is a component of a machine that produces force, torque, or displacement, usually in a controlled way, when an electrical, pneumatic or hydraulic input is supplied to it in a system (called an actuating system ). [ 1] An actuator converts such an input signal into the required form of mechanical energy.
Pneumatic rack and pinion actuators for valve controls of water pipes. A pneumatic actuator mainly consists of a piston or a diaphragm which develops the motive power. It keeps the air in the upper portion of the cylinder, allowing air pressure to force the diaphragm or piston to move the valve stem or rotate the valve control element.
An F-14 Tomcat descends to make an arresting gear landing on the flight deck of USS Theodore Roosevelt (CVN-71) in 2002. An arresting gear, or arrestor gear, is a mechanical system used to rapidly decelerate an aircraft as it lands. Arresting gear on aircraft carriers is an essential component of naval aviation, and it is most commonly used on ...
An electrical fusible link is a type of electrical fuse that is constructed simply with a short piece of wire typically four American wire gauge (AWG) sizes smaller than the wire that is being protected. For example, an AWG 16 fusible link might be used to protect AWG 12 wiring. Electrical fusible links are common in high-current automotive ...
In general, valves are designated as 2/2 DCV, 3/2 DCV, 5/2 DCV, 5/3 DCV etc., in which the first number indicates number of ports and second number indicates number of positions. To change the position, the valves are generally actuated by: Pedal operated; Push button operated; Spring operated; Solenoid operated; By using the pneumatic source ...
