FAQ Question?What is the difference between the DG..U and DG..H versions of this pressure switch? Answer:The ‘U’ in DG 50U-3 indicates a standard pressure switch that breaks the circuit on rising pressure (acting as a high-pressure cutout). The ‘H’ version would make the circuit on rising pressure. It’s crucial to select the correct type for your safety logic. Question?Can this DG 50U-3 switch be used for biogas or gases with high hydrogen sulphide content? Answer:No, the standard DG series is designed for natural gas, LP gas, and air. For special gases like biogas, which can be corrosive, Kromschroder offers specific versions with suitable materials. Always consult the datasheet for media compatibility. Question?How do I correctly set the switching point on the DG 50U-3? Answer:The switching point is adjusted using the hand wheel under the transparent cover. The scale is in mbar. For precise setting, it is recommended to use a calibrated manometer connected to the test port to verify the exact pressure at which the switch actuates. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
