33.061/1 Sauter Components DSDU: Transducer for differential pressure How energy efficiency is improved Simplest conversion of pressure differences into proportional standard signal. Areas of application For measuring pressure differentials in liquids, gases and vapours. Non-wearing measurement procedure by means of contact-free inductive signal conversion. Features • Pressure differential measuring range: 0 to 6 bar • Standard signal 0(2) to 10 V or 0(4) to 20 mA • Up to 110 °C and up to 10 bar maximum sensor values • 24 V~/=, ± 20% supply voltage Technical description • Light-alloy housing with transparent cover made of impact-resistant thermoplastic • Ambient temperature: -20 to +70 °C • IP65 • Standard housing-mounted plug with cable connector for cables from 6 to 10 mm in diameter • Extensive range of accessories Operation The pressure difference in the sensor acts on a bourdon tube, thereby creating 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 of stainless steel (material nos. 1.4104 and 1.4541) To protect the DSDU with a fuse, a fuse of at least 250 mA/250V should be used.
