Curtiss-Wright launches compact 3-slot chassis for data acquisition in constrained spaces

0

Curtiss-Wright has expanded its Axon data acquisition range, which is used in flight test instrumentation systems, with two new ultra-compact 3-slot chassis

The AXN/CHS/03U chassis is designed for use with Axon AXN data acquisition modules and the ADAU-2003-1 chassis is designed for use with Axon ADAU modules.

The small chassis enables flight test instrumentation engineers to more easily architect high throughput data acquisition systems that can be located much closer to the point of measurement. This helps to minimize the length of cabling to sensors and busses, reducing signal interference and optimizing measurement accuracy.

The chassis are suitable for use in locations on an aircraft where little free space is available, such as aircraft wings, but more data acquisition is required than can be supported using Curtiss-Wright’s remote Axonite single module housing.

Lynn Bamford, president of defense and power at Curtiss-Wright Defense Solutions said,  “These two new 3-slot chassis further enhance the flexibility that our Axon product family brings to flight test programs.

“Their ultra-compact form factor means flight test engineers can easily and rapidly add three data acquisition modules to space constrained locations, hitting the sweet spot between a 6-slot chassis and our remotely placed single module Axonite housings.”

The chassis support a wide range of operating inputs, advanced protection with fault monitoring, and glitch immunity and provide an isolated 50W power supply for controller and user-modules. For maximum flexibility, any user-module can be placed in any user-slot and in any combination. User-modules may also be remotely located via use of an Axonite housing that enables a single module to be located remotely from the main chassis.

The AXN/CHS/03U and ADAU-2003-1 join the product families’ 6, 9 and 16 user slot chassis, to address application where FTI engineers seek to optimally balance channel count vs. chassis size.
