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 to 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.
