New Axon™ AXN/ADC/406 and ADAU ARTD-416A-1 modules support 16 RTD channels in a single slot with extremely high accuracy

ASHBURN, Va. – May 11, 2020 – Curtiss-Wright’s Defense Solutions division today announced that its Aerospace Instrumentation (AI) group, a trusted leading supplier of flight test instrumentation (FTI) system solutions, has introduced two analog-to-digital-conversion (ADC) module variants for use with Resistance Temperature Detector (RTD) sensors used in flight test and monitoring programs to accurately measure the temperature of engines and other critical components. The ability to connect to multiple RTDs from a single highly accurate ADC module enables FTI engineers to save valuable weight, slot count and cost when configuring their FTI data acquisition unit (DAU).

The new AXN/ADC/406 module is designed for use with Curtiss-Wright’s AXN family of DAUs, while the ARTD-416A-1 is optimized for use with Curtiss-Wright’s TTC family of ADAUs. Both variants can acquire sensor data from up to 16 RTD channels on a single module. Unlike legacy products that restrict all channels on similar cards to the same RTD type, the AXN/ADC/406 and ARTD-416A-1 enable different RTD types to be supported on each channel. These ADCs can be configured as either 2-wire or 3-wire and provide maximum sampling rates of 6.25 ksps per channel with a measurement bandwidth of 1.5625 kHz. With a temperature input range of -200°C to 850°C, these two compact modules deliver extremely high accuracies:

  • Typical 0.25°C between -50°C and +250°C for PT-100 with 2.5mA excitation
  • Typical 0.4°C between -200°C and +660°C for PT-100 with 1.5mA excitation
  • Typical 0.25°C between -50°C and +250°C for PT-1000 with 2.5mA excitation
  • Typical 0.4°C between -200°C and +660°C for PT-1000 with 1.5mA excitation

“We are excited to continue to add industry-leading functionality to our range of fully integrated data acquisition systems for flight text programs,” said Lynn Bamford, President, Defense and Power. “With the introduction of these new ADC modules for RTC temperature sensors, we further enhance the capabilities of our Axon and TTC DAU solutions, with support for a huge number of channels on a single module and industry leading signal accuracies. Even better, they add flexible RTD support, error correction and advanced filter settings to deliver unmatched capability.”
