Overview

The GRANITE™Chassis is a platform for housing a complete GRANITE system. The Chassis can hold up to eight modules, which may include the DAQ (GRANITE™10, GRANITE™9, or GRANITE™6), CH400, and additional GRANITE measurement modules. Portability and protection are fundamental to the design, delivering optimal system performance in demanding conditions—especially when heat must be dissipated quickly. Up to five panel faces (four top, one rear) can be customized to mount a wide variety of connectors, providing rapid connection to the DAQ system, which is ideal for time-sensitive or repetitive testing applications. As a GRANITE system scales to larger arrays of sensors and supporting GRANITE modules, several additional Chassis can be daisy-chained to expand the GRANITE DAQ network. With the optional 38822 Rackmount, Slide-Rail Kit, the Chassis can be easily mounted in a standard four-post server rack cabinet.

Technical Description

The GRANITE™Chassis is ideal for high-performance applications such as high-speed DAQ, large-channel-count DAQ, structural health monitoring, distributed data acquisition, vehicle testing, charging large battery banks, and when using sensors or auxiliary system components that draw significant power. Typically, the CH400 is paired with the Chassis to deliver reliable power in demanding applications such as these. An automated thermal management system efficiently controls and dissipates heat incrementally to suit a range of dynamic operating conditions.

The GRANITE Chassis provides a very rugged framework that consolidates GRANITE measurement modules and provides physical protection in industrial environments. It includes connections for easy power distribution to measurement modules and/or additional Chassis—whether they are collocated or mounted distantly. The integrated battery temperature sensor provides feedback to a CH400, ensuring the battery is optimally maintained. The onboard battery and the ability to add external battery banks make the GRANITE family of products perfectly suited for off-grid, solar-powered systems; locations where on-grid systems may be susceptible to frequent downtime; and critical applications that require absolute reliability in monitoring, notification, and/or control capabilities.

Panels designed for customization are made of 5052 aluminum and can be modified as desired. (Note: Modifications should occur while the panel is removed from the Chassis.) Alternatively, custom panels can be designed and fabricated. Contact Campbell Scientific to discuss this customization, as well as installing and terminating the wiring of custom connectors to GRANITE modules for a complete plug-and-play system that is tailored to your specific application.
