Definitions for "Dead Band"
Keywords:  input, band, span, overcontrol, sensor
A range of input signals for which there is no system response.
The range through which the input may be varied without initiating a response. Usually expressed as a percentage of full-scale range.
An area of a sensor that does not promote change in the signal being supplied to the control station. A wider dead band in the sensor allows more web deviation from the desired set point. The sensor may be sensing alignment of the web path, web tension, transparentness of web, or web continuity. Dead band width does not increase or decrease machine response time (gain control), but a wider one can be used to reduce overcontrol of web steering devices by not disturbing the steering device with minor web edge flutter.
Keywords:  brake, neutral, minimum, drive, center
The space between Minimum Brake and Minimum Drive, with Neutral located at the center of this space.
The region of signals close enough to the set point of a controlling instrument that they do not initiate a cycle of corrective action. Similar to the noise level of a monitoring instrument.
