A ________ is paired with a scale that encodes position
____ _____ is the quantification of of bulk fluid movement
An _______ is a fail-safe control switch or circuit that, when de-energized, will stop the operation of associated equipment and will shut off all potential hazards outside the main power enclosure
A _____ stop function is a controlled stop with power left available to the machine actuators
A ______ is a device that converts a physical stimulus or output variable (such as temperature, force, pressure, or displacement) into amore convenient form (usually an electrical signal) for the purpose of measuring the output
a ______ is a sensor that detects the presence of an object by changes in light
______ are sensors that detect position and speed by converting rotational mechanical displacements into electrical signals and processing those signals
A _____ stop function is a controlled stop with power to the machine actuators available to achieve the stop then power is removed when the stop is achieved.
in a _______ control system, the output of the process (controlled variable) is monitored by a sensor
the double slit in a decoder helps determine ______
A sensor is a ________, which is a device that converts a physical variable of one form into another form
- A time-driven sequence is _______ (no feed-back)- An event-driven task is ________ because a feedback signal is required to specify when the task is finished
An ______ is a feature that makes the state of two mechanisms or functions mutually dependent
A _______ stop function is an uncontrolled stop by immediately removing power to the machine actuators
______ are temperature sensors that contain a resistor that changes resistance value as its temperature changes
in a discrete control system _____ are changes that are executed by the controller when either at a specific moment or after a certain lapse of time
a ______ is a switch operated by the motion of a machine part or presence of an objectthey have _____ or contact closure
a _____ sends ultrasonic waves from an emitter toward a sensing object, then receives the reflected waves with a detector. The Sensor uses the resulting information to determine the presence of an object, or to measure the distance to the object
