Product comparison
Type Adjustment range for upper trip pressure* switching difference (hysteresis) Tolerance at adjusted switch-point
DPS200 20…200 (Pa) 10 (Pa) ±20%
DPS400 40…400 (Pa) 20 (Pa) ±15%
DPS600 50…500 (Pa) 20 (Pa)
DPS1000 200…1000 (Pa) 100 (Pa)
DPS2500 500…2500(Pa) 150 (Pa)

*The trip pressure refers to vertical mounting. In case of horizontal mounting (with the cover pointing upwards), the range values increase by 20 Pa.
