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.
