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.
The range through which an input can be varied without initiating an observable response. Dead band is usually expressed in percent of span
The values to which a system input can be changed without causing a corresponding change in system output.
The range through which an input can be varied without causing a measurable response. Dead band is usually expressed in percent of span.
The range in which input can vary without causing an observable output change.
The range through which an input can be changed without causing an observable response.
The temperature band where no heating or cooling takes place, expressed in degrees.
A specific range of values in which an input signal can be altered without causing a change in the output signal.
The range through which an input can be varied, upon reversal of direction, without causing an effect in the output signal.
The air gap distance in front of the transducer that cannot be measured by the sensor.
1. For chart records: the minimum change of input signal required to cause a deflection in the pen position. 2. For temperature controllers: the temperature band where heat is turned off upon rising temperature and turned on upon falling temperature expressed in degrees. The area where no heating (or cooling) takes place.
A range of values where a setpoint controller will not send any correction signal. For example, if the set point temperature was 21C with a dead band of + 2 C, the set point controller would send no correction signal until the temperature was higher than 23C or lower than 19C.
