Glossary
A/D Converter A device that converts an analog voltage to a digital representation.
Analog Output
Output voltage of a system that is a continuous function of the target position relative
to the sensor.
Dimensional
A standard of measurement or precision reference against which one correlates
Standard the output of the system, i.e. a micrometer fixture, feeler gauges, precision ceramic
spacers, etc.
Drift Undesirable change in system output over a period of time while the sensor / target
position is constant. It may be unidirectional or cyclical and caused by such things
as aging of the electrical circuits or environmental changes impacting the system.
Effective
An application dependent value determined by multiplying the equivalent
Resolution input noise specification by the square root of the measurement bandwidth.
Equivalent RMS A figure of merit used to quantify the noise contributed by a system component.
Input Noise It incorporates into a single value factor influencing a noise specification, such as
signal-to-noise ratio, noise floor, and system bandwidth. Given a measurement
system’s sensitivity and the level of “white noise”, equivalent RMS input noise can
be expressed in actual measurement units.
Full Scale Output
The voltage output measured at full-scale displacement for which a system is
(FSO) calibrated. The algebraic difference between end points.
Gain
The function of increasing and decreasing sensitivity. Changing gain will increase
or decrease the slope of the output curve.
Iteration
Repetition.
Linearity
The closeness of a calibration curve to a specified straight line.
Loading
The affect of conductive materials positioned within 3 times the diameter of a
sensor, that are a permanent part of the measuring environment.
