SENTINEL™ 1075 SCARPro.

Experience 24/7 SCAR Productivity.

Perform Small Controlled Area Radiography (SCAR) radiographic inspections in close proximity to other trades, nucleonic process control equipment, and critical safety systems, such as visual flame detectors, to minimize the impact of RT on continuing operations or outage schedules.

With the SENTINEL 1075 SCARPro, you can obtain up to 98% reduction in exclusion zones compared to conventional radiography techniques.

Designed, tested, and manufactured to the requirements of ANSI N432-1980, ISO 3999:2004(E), IAEA TS-R-1 (2009), IAEA SSR-6 (2012), USNRC 10CFR34, USNRC 10CFR71, and USDOT 49CFR173.

Minimize Exclusion Zones

With the SENTINEL 1075 SCARPro, you can obtain up to 98% reduction in exclusion zones compared to conventional radiography techniques.

Utilizing FlexShield radiation blankets, guide tube shields, and scatter shields with proper technique, you can achieve exclusion zones as small as 3 to 6 feet (1 to 2 meters) for demanding applications or 10 to 15 feet (3 to 5 meters) for typical applications required by clients to realize the SCAR value.

QSA Global, Inc.’s sales team and local distributors provide custom-tailored solutions to help your clients maximize turnaround efficiency, eliminate interference from radiographic testing on nucleonic process control gauges, and meet exclusion zone requirements.

	Shooting Windows	Production	Welds /Shift
Traditional RT in Shooting Windows	1 hr shift change + 0.5 - 1 hour lunch	10 welds / hour	15-20
24/7 RT with SENTINEL 1075 SCARPro	24/7 continuous operations	3-4 welds / hour	36-48

During turnarounds and outages, traditional gamma radiography is either performed in shooting windows totaling only 1-2 hours in a 12-hour shift or other trades such as welders and electricians must be cleared from the exclusion zone while radiography is performed.

The SCAR Radiography technique utilizing the SENTINEL 1075 SCARPro eliminates the need for shooting windows or impacting other trades. The SENTINEL 1075 SCARPro enables continuous 24/7 gamma radiography inspections maximizing inspection productivity and accelerating your turnaround.

Gamma rays, x-rays, and scatter radiation from radiographic testing can interfere with nucleonic process control gauges and critical safety systems such as visual flame detectors (VFDs) commonly found in oil refineries, petrochemical plants, and power plants. Nucleonic gauges utilize radiation in myriad process control applications including measuring process fluid density, locating phase interfaces, and level switches. UV VFDs detect UV radiation from fires and can trigger fire suppression systems. These systems often cannot differentiate the radiation they are designed to detect from radiation resulting from radiographic testing. As a result, critical processes may need to be manually monitored, operated without real-time process information, or shut down entirely while traditional radiographic testing (RT) is being performed.

The SCAR radiography technique allows you to perform RT in close proximity to these sensor systems without risking interfering with process measurements or generating false alarms in critical safety systems.

Contact Fixture Configuration

The SENTINEL 1075 SCARPro comes standard with a contact fixture kit to perform category I close-contact SCAR radiography. The contact fixture kit allows you to securely mount the exposure device to any diameter pipe. Contact shots are typically preferred on piping 3" OD and above.
Offset Fixture Configuration

An optional offset fixture kit is available when you require an increased source to film distance (SFD) for small piping, typically 2" and below. The offset fixture kit allows you to achieve the necessary SFD to perform superimposed and elliptical shots. The offset fixture kit securely mounts the source projector in any orientation. If the pipe itself is not suitable for mounting due to insulation, thin wall, access, or other issues, the offset fixture kit can easily be attached to other nearby piping or even structural material and the components can be configured to aim the SENTINEL 1075 SCARPro's collimated beam at the sample.
Projection Style Configuration

Using a standard SENTINEL guide tube, guide tube shield, controls, and external collimator, the SENTINEL 1075 SCARPro operates as a category II projection-style gamma radiography source projector to perform industrial axial, radial and panoramic exposures in tight access areas where the body of the gamma-ray projector will not fit. Interchangeable front plates allow for standard guide tube application or direct contact shots.
