Sentinel 1075 SCARpro

SENTINEL Model 1075 SCARPro source projector is used for industrial non-destructive testing applications of gamma radiography with Selenium-75.

SCARProcan be used as a category I or II exposure device. When used in SCAR mode (category I), the SCARPro allows radiography to be performed in congested work areas with a minimal distance to the controlled areas.

When used as a traditional projector (category II), standard SENTINEL source guide tubes and collimators allow the Selenium-75 source to be used for axial, radial and panoramic exposures.

Exposure Device
Model 1075 SCARPro is a dual mode radiographic exposure device for Small Controlled Area Radiography and traditional projection radiography.

An interchangeable collimator with a 90o incremental adjustment enables safe radiography in areas congested with workers.

A standard guide tube attachment with an ISO compliant interlock enables traditional axial and radial projection radiography.

Sentinel Sentry Projector

The SENTINEL SENTRY models 330 and 110 are mobile industrial radiography exposure devices for use in the field.

The exposure device body consists of a titanium ā€˜Sā€™ tube and cast depleted uranium (DU) shield contained within a welded stainless steel cylinder. These devices have an automatic securing mechanism that automatically secures the source assembly when retracted into the fully shielded position.

Both devices include a handling rib assembly that helps to facilitate lifting and increases the ease of movement of the device. A key safety feature is that both the automatic securing mechanism and front port cover are protected by stainless steel tube extensions that are welded into the main body of each device.

The rear plate port weldment is designed to provide easy access to the locking mechanism and source assembly connector for connection of the SENTINELTM control assembly. The front plate port weldment is designed to provide easy access to the outlet port for the connection of the guide tube with bayonet assembly.

Sentinel 880 Delta Source Projector

SENTINEL Model 880 Delta source projector is portable, lightweight and compact industrial radiographic exposure device.

Model 880 series source projectors are used for industrial applications of gamma radiography to inspect materials and structures in the density range of approximately 2.71 g/cm3 through 8.53 g/cm3.

SENTINELTM Model 880 Delta, 880 Elite and 880 Omega source projectors are portable, lightweight and compact industrial radiographic exposure devices. The patented device body consists of a titanium ā€˜Sā€™ 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.

The horizontally oriented design allows the locking mechanism, source assembly connector and outlet port to be easily operated, simplifying connection of source guide tubes and remote controls.

Exposure Device
The exposure device body, containing the DU shield, locking mechanism, outlet port, protective covers and required labels*, comprises the radioactive material transport Type B(U) package.

Removable Jacket
An impact resistant plastic jacket surrounds the exposure device to protect labels and provide the means for carrying and placement 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.

Flexshield Radiation Protection

FlexShield radiation shielding maximizes shielding effectiveness while keeping the weight to a minimum. The bismuth attenuating material is an ideal alternative to lead.

Applications that require flexibility, such as small bore pipe, elbows, and valves are no problem for FlexShield.

FlexShield radiation shielding is available in standard and custom length flat sheets and guide tube shielding. PVC covers come standard with flat sheets to protect against harsh operating environments.

Gromets and handles for easy installation and handling are also standard. FlexShield provides the necessary protection for any NDT company.
