SENTINEL DELTA 880 Series Projector

SENTINEL™ based at the QSA Global, Inc. facility in Burlington, MA., has a worldwide reputation for quality, reliability and safety to offer a comprehensive range of NDT equipment and accessories, including gamma radiography projectors, x-ray equipment, liquid penetrant and magnetic particle inspection materials. SENTINEL™ produces a complete range of radiography sources (Iridium-192 (IR-192), Cobalt-60, Selenium-75 (SE-75) and Ytterbium-169) as will as source holders that are fully compatible with all leading makes of projector.

SENTINEL™ 880 Delta Elite and Omega source projectors are portable, lightweight, compact industrial radiographic exposure devices. The patented device body consists of a titanium ‘S’ tube and cast depleted uranium (DU) shield contained within a 300 series stainless steel tube with stainless steel discs welded at each end forming a cylinder shaped housing. The discs are recessed to provide protection for the rear mounted locking mechanism and front mounted outlet port.

Key Features

  • The horizontally oriented design allows the locking mechanism, sourceassembly connector and outlet port to be easily operated, simplifyingconnection of source guide tubes and remote controls.
  • The internal void space of the housing is filled with rigid foam to prevent the ingress of water or foregn material, but is open to atmospheric pressure.
  • The exposure body, containing the DU Shield, locking mechanism, outlet port, protective covers and required labels, comprises the radioactive material transport type B package.
  • An impact resistant plastic jacket surrounds the exposure device to protect main body, outlet port, lock mechanism and labels from accidentally damage. Besides, the removable jacket provide the means for carrying and replacement during radiographic operations. The three models are identified by jacket color; yellow for the 880 Delta, blue for the 880 Elite and orange for the 880 Omega.
  • The exposure device alone, continue to be a compliant of Type B package even if the jacket has been removed.
  • The shaped base and feet, and low center of gravity provide greater stability on convex and concave surfaces.


Model 880 series source projectors are used for industrial applications of gamma radiography, mainly with Iridium-192, to inspect materials and structures in the density range of approximately 2.71g/cm3through 8.53g/cm3. Low energy isotopes can be accommodated to permit radiography of materials and structures of thin sections of steel and low-density alloys. The 880 series exposure devices are also designed for use with low activity sources with high photon energies for mass absorption (gamma scanning) studies of high-density materials up to 18.7g/cm3.
