Offering an easy-to-use but accurate means of measuring displacement from a fixed point, the DWT transducer from RDP Electronics is well suited to such diverse applications as control of press height or furnace doors.
Based on the draw wire principle, the transducer body can be bolted to a reference point and the draw wire attached to the moving part of the system, allowing point-to-point measurement or even around corners. The draw wire is plastic coated and has a spring-loaded reel to maintain cable tension. The DWT is available in standard or rugged enclosure versions and can have LCD display as an option. There are various measurement ranges from 600mm up to 3,500mm. Non-standard ranges up to 7,500mm can also be accommodated. Typical analogue outputs include 4-20 mA and 0-10V.
