A/D converter module for DTC pressure scanners in flight test applications introduced by Curtiss-Wright

ASHBURN, Va. – The Curtiss-Wright Corp. Defense Solutions Division in Ashburn, Va., is introducing the KAD/MDC/105 A/D converter card for flight test, engine test, and pressure measurement in commercial and defense fixed-wing aircraft and helicopters.

The KAD/MDC/105 module interfaces to multiplexing digital temperature compensation (DTC) pressure scanners to acquire pressure and temperature data during flight test by interfacing to DTC pressure scanners. The module is part of the company's KAM-500 flight test instrumentation (FTI) modules.

The rugged module supports dual 64-channel DTC pressure scanners, and can read scanner memory as quickly as 50 kilosamples per second per channel. It applies DTC correction algorithms to ensure accurate data, and supports the re-zeroization of the scanner device and stores any corrections in on-module non-volatile memory.

In addition to measurement channels, the KAD/MDC/105 also provides individual 6-bit address buses and power supplies. In addition, each address bus serves as a DTC scanner communication interface to set up the scanner, read DTC calibration memory, measure internal scanner excitation, and check the scanner's manifold position.

The KAD/MDC/105 sequentially addresses 64 multiplexed channels of DTC pressure scanners and measures voltages to further process their outputs according to DTC algorithms based on scanner calibration data.
