33.051/2 DSU Operation The pressure in the sensor acts on a bourdon tube, thereby producing a force on the conversion spring. The resultant movement is converted into a standard electrical signal by an inductive distance sensor. The output signal rises in proportion to the pressure. Additional details Materials which come into contact with the medium are: brass, stainless steel and the seal's nitrile rubber (on the brass pressure sensor); stainless steel (on the stainless-steel sensor) material no. 1.4104 and 1.4541. To protect the DSU with a fuse, a fuse of at least 250 mA/250 V should be used....
