Switching device Seawater resistant die cast aluminium GD AI Si 12. Protection class IP 65 Pressure sensor materials See Product Summary Ambient temperature –20 to +60°C. At ambient temperatures below 0°C, ensure that condensation cannot occur in the sensor or in the switching device. Maximum working pressure See Product Summary Mounting Either directly on the pipe or with two 4 mm ø screws on the wall surface. Mounting position Vertically upright Setting Continuously adjustable via the setting spindle with a screw driver. The set switching pressure is visible in the scale window. Switching differentials Largely independent of the set switching pressure. Not adjustable. For values see Product Summary. Pressure measuring connection Care must be taken to ensure that a pressure measuring connection is availab
