?   is the set of values over which measurements can be made by a device without changing the device's sensitivity.

The   ?   is the variable for which supply and demand must be balanced. It is a physical or chemical change of matter and/or conversion of energy.

A   ?   is information in the form of a pneumatic pressure, an electric current, or mechanical position that carries information from one control component to another.

A   ?   is any variable property of a process. It is the part of the process that changes and, therefore, needs to be controlled.

A   ?   is the primary source of instrument information when ordering, designing, installing, maintaining, and calibrating an instrument.

A(n)   ?   is a process and instrumentation drawing or diagram.

A(n)   ?   is a control signal that is on or off, open or closed, run or stop, etc.; one of two possible states or conditions.

 ?   is a term used broadly to describe any device that performs a measuring or controlling function. The process variables measured by the device may be used for indication, recording, or control.

  ?   is the difference between the upper and lower limits of a range that is expressed in the same units as the range. It is the difference of the URV and LRV.

The   ?   is the part of a loop or instrument that first senses the value of a process variable and assumes a corresponding, predetermined, and intelligible state or output. The sensor may be separate from, or integral with, another functional element of the loop. It is also known as a detector or sensor.

 ?   is the process of adjusting an instrument by compiling a deviation chart so that the instrument output can be correlated to a known standard input value.

A   ?   is a drawing used to represent the interconnection of the control loop devices, their location in the process, and a traceable signal path between the devices.

A   ?   is the desired value where a process should be maintained. The value may be manually set, automatically set, or programmed. It is expressed in the same units as the controlled variable.

A(n)   ?   is a signal that uses binary (0 or 1) digits to represent continuous values or discrete states.

  ?   is a departure from a desired value. It is the difference between the value of a specific variable and some desired value, usually a set point.

A(n)   ?   is a device that senses a process variable through the medium of a sensor and converts the input signal to an output signal of another form. The output of the device is a steady-state value that varies only as a predetermined function of the input (process variable). The sensor may or may not be integral with this device.

A   ?   is a process under control, whereby an instrument measures a process variable and the data is manipulated by a controlling device, which sends corrective data to a final control element to appropriately adjust the process variable; the process automatically repeats.

A   ?   is a device having an output that changes to regulate a controlled variable in a specific manner.

he   ?   is the component of a control system that directly regulates the flow of energy or material to the process. The device directly controls the value of the manipulated variable of a control loop. Often it is a valve.

A(n)   ?   is a continuous operating signal that is a continuous representation of a physical quantity, property, or condition. The signal may be transmitted as pneumatic, mechanical, or electrical energy.
