MPS-2 SWITCH  OUTPUT MODE

 

HYSTERESIS DEFINITION

 

Hysteresis Mode (HYS): This output mode programs the sensor to control the output signals "NPN or PNP" with switch points "H-1" (output 1) and "H-2" (output 2) on the graph below.  The switch points are adjustable by touch panel and independent.  The Hysteresis is a value "h-1/h-2" to control  the output signals below the switch point "H-1/H-2".  This is adjustable on the sensor and mathematically defined as: 

 

       (switch point)      "H-1/H-2"

                                                                       MINUS                                                                     

                                                 (Hysteresis value)  "h-1/h-2" 

                                                                               HYSTERESIS RANGE

WINDOW COMPARATOR DEFINITION

 

Window Comparator Mode (CNP):  This output mode programs the sensor to provide an output signal "NPN/PNP" between switch points "A" and "B" on the graph below.  The switch points "A-1/A-2" (low point) and "B-1/B-2" (high point) are independent and adjustable on the sensor.  The window comparator mode is sometimes referred to as a "High/Low" setting or a "Failure prediction mode".  The reference depends on the application and pressure ranges.
