Remote Digital Fluid Pressure Transducer
Drallim’s Remote Digital Transducer forms part of a new product range combining microprocessor techniques with Drallim’s long distance two-wire digital multi-drop protocol. This has been established and proven for many years in the international telecommunications sector.
RDT Features:
• Genuine two-wire digital multi-drop signalling, allowing signal and power to be superimposed on the same twisted pilot pair.
• Up to 99 individual mixed type RDTs can be addressed sequentially on each pilot pair.
• Remote operation offering up to15 kilometres.
• Longer distances achieved when used in conjunction with Signal Repeater Unit.
• Superior pressure measurement accuracy with on-board temperature compensation.
• Environmental Protection: IP68 Rating, (2 metres submersion).
• Integral 15kV induced protection for installation on auxiliary pilot cables.
• Ergonomically designed PVDF enclosure.
• Resistant to corrosive effects of dielectric fluids.
• 40 Years processor memory charge storage EEPROM, recalibration schedules available.
• Universal termination components offering standard BSP hydraulic connections.
• Optional ‘Quick-fit’ hydraulic coupling and electrical ‘plug and socket’ devices available.
• NGC Type-Test approval for installation on circuits up to and including 400kV.
For the accurate and reliable long-term measurement of dielectric fluid pressures in transmission and distribution self-contained oil-filled cables up to and including 400kV.
