Pressure switch MDR 11 Dimensions, Accessories MDR 11 Explanation Devices with differential pressure adjustment An intersecting point is determined in the diagram by selecting a pair of cut-in and cut-out pressure values. If this point lies within thebshaded area, this pair of values can be set on the pressure switch. If this point lies outside the shaded area, these values cannot be set. Example: MDR 1/11 with differential pressure adjustment With a preselected cut-in pressure of 4 bar, the cut-out pressure can be determined and set between 5.4 and 8 bar using the differential pressure adjustment....
