Setting Continuously adjustable via the setting spindle Calibration with a screwdriver. The set switching pressure is visible in the scale window. The DGM series is calibrated for rising pressure. This means that the adjustable switching pressure on the scale corresponds to the switching point at rising pressure. The reset point is lower by the amount of Sealing P2 the switching differential. (See also page 27, 2. Calibration at upper switching point). On request (can be fitted later). Switching differentials For other pressure ranges see type series DWR, page 59. Largely independent of the set switching pressure. Not adjustable. For values see Product Summary.
