The primary function of the C-frame is to position a calibrated and geometrically correct x-ray beam on a product.

     Due to its so-called "low-tech" contribution to the overall gauging process, the C-frame is often thought of as little more than a moving "bracket".  This description, although somewhat accurate, implies that the design considerations for this item are not really critical to system performance.  This erroneous view can generate very costly problems for both vendors and customers.

     Our design parameters (described below) address all the areas of concern in the production of a C-frame that will give you years of trouble-free service.

• Geometry - The x-ray generator is mounted in the "rigid" lower member of the C-frame.  A vertical section at the rear of this lower member sets the height and provides  a mount for the detector arm.  During periods of C-frame travel, the pivotable axle on the front wheel assembly of the frame precludes the possibility of any frame "twist", which would adversely affect beam alignment.

• Serviceability - Use of only "standard" wheels, bearings and hardware reduces most maintenance to "nuts and bolts".

• Protection - The "ruggedized" construction of the frame and covers affords physical protection to internal components.  This protection is further extended through the use of shock absorption materials, wherever practical.  "Guard rings" are provided around x-ray windows and cables are strain relieved, in an effort to minimize all areas of component vulnerability.

• Ease of Installation - Whenever possible, a survey of the intended gauge location is made to resolve a number of questions that can significantly affect installation costs and effort.  If the application is "new", our standard mounting arrangements can often be customized to utilize existing support members in the installation area.  If the application is an "update" or "replacement", significant savings can often be achieved by designing to mate with existing tracks, trolleys and festoons.

• Application - The C-frame will generally have an air gap of 18" and a throat depth to suit the strip width.  C-frame traverse will be through the use of an electric motor arrangement supplied by Connecticut Industrial Gauging, Inc.
