dead band

[′ded ‚band]
(electricity)
The portion of a potentiometer element that is shortened by a tap; when the wiper traverses this area, there is no change in output.
(engineering)
The range of values of the measured variable to which an instrument will not effectively respond. Also known as dead zone; neutral zone.

The total airflows at full cooling and the beginning of the dead band are then calculated.
The typical sequence is as follows: when the signal from the AO modulates from 2 to 5 Vdc, CHW flow is modulated from full open to zero flow; from 5 to 7 Vdc, all ports are closed (dead band); from 7 to 10 Vdc, HW flow is modulated from zero flow to full open.
Dead band and % HR values are significantly lower than that of conventional one (lesser are better).
On the other hand, a large dead band is not always necessary given the fact that the reverse conduction mode of GaN HEMTs is totally different from Si MOSFETs.
Due to the effect of speed governor dead band, the position of governor control valves, an increase/decrease in speed can occurs before the valve position changes (Hope and Malik (1982); Anand and Ebenezer Jeyakumar (2009 a); Anand and Ebenezer Jeyakumar (2009 b); Nanda and Kaul (1978); Jagatheesan and Anand (2012)).
* Electrical angles up to 360[degrees] with no dead band.
Measuring values such as hysteresis, dead band and step response against the ideal can provide early indication of underlying problems like underpowered and/or inaccurate control.
If you could pick any dead band to get back together or reunite, who would it be?
The valve siphon tube provides a dead band to prevent rapid cycling of the pressure and opening and closing of the shutoff valve."
Servovalves are generally distinguished from other types of electrically controlled valves by characteristics like low power electrical input signals, linear output/input, negligible dead band and high output dynamic response bandwidth [2].
The RD-100W receiver allows for in cab on-grade matching and on-grade accuracy adjustments (dead band) and 2-way communication between the receiver and the remote display.
