Overview

The Granite™Chassis is a platform for housing a complete GRANITE system. The Granite Chassis can hold up to eight modules, which may include the DAQ (Granite™10, Granite™9, or Granite™6), 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 Granite Chassis can be daisy-chained to expand the GRANITE DAQ network. With the optional 38822 Rackmount, Slide-Rail Kit, the Granite Chassis can be easily mounted in a standard four-post server rack cabinet.

Unique, rugged design for maximum system protection when used in harsh, demanding applications
Automated thermal control to quickly dissipate heat generated by GRANITE modules
More than 150 cable-tie points for convenient cable management
Optional built-in AC/DC converter for powering system using AC power
Integrated high-performance 8 Ah battery for portable, uninterrupted operation
LED illumination, showing at a glance that the system is powered
Integrated battery temperature sensor for optimal charging and maximizing battery life
Integrated tool bracket to keep supplied screwdrivers readily available
Spring-loaded rugged handles to securely grip Granite Chassis and DAQ components while carrying
Four anchor points to attach tie-down straps
Rack mountable with optional accessory kit (occupies 7U)
Rapid, tool-less removal of top cover, facilitating module installation and providing flexibility to quickly move covers between Granite Chassis
Customizable, removable connector panels to support quick deployments and repetitive testing

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. 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 Granite Chassis—whether they are collocated or mounted distantly. 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 Granite 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.
