Adjustable hysteresis
The difference between the switching point (SP) and return
point (RP) is known as a hysteresis. On electronic pressure
switches, any hysteresis can be selected within the mea-
suring range.
Hysteresis function: the hysteresis keeps the switching
status of the outputs stable, even if the system pressure
fluctuates either side of the setpoint value. The output is
activated when the system pressure rises and the relevant
switching point (SP) is reached. The output is deactivated
when the pressure decreases again and the return point
(RP) is reached.
Adjustable window
The output function is activated when the measured value
falls between the preset switching and return point.
Window function: the range between a defined lower
pressure limit and a defined upper limit is known as a
window. A switching operation is initiated as soon as the
upper or lower limit of the programmed pressure range is
exceeded.
Adjustable delay time
Delay times can reliably filter out undesired pressure peaks
that occur momentarily. The status of the switching output
does not change immediately after the switching event
occurs, but only once a preselected delay time of 0...50 s
has elapsed. If the switching event no longer exists by the
time the delay has elapsed, the switching output does not
change.
