Page 15: Scope
Manufacturers are responsible for qualifying, validating, and certifying their products for their intended uses and meeting all applicable regulatory requirements. The 2315NDT CMOS X-ray detector contains specific models for which the main difference is the scintillator or X-ray shielding of the flat panel X-ray detector. Final application and intended use is determined by the X-ray system manufacturer and is based on the completed X-ray system design. -

Comparison of v1 and v2 Detectors The 2315NDT detector is based on a CMOS 1512 v2 sensor, which is an update of the already existing v1 sensor, used previously. The aim of the update was to implement functional and per- formance improvements and to solve some known issues, and meanwhile keep the detectors backwards compatible. - Page 17 2315NDT v2 CMOS X-ray Detector User Manual Table 1 List of discrepancies between v1 and v2 detectors Parameter v1 sensor v2 sensor Readout column There are 6 readout columns There is a dead column in each sensor (x=9 evenly spread in each sensor.

2315NDT v2 CMOS X-ray Detector User Manual Power supply voltages must be high enough to overcome a WARNING voltage drop caused by conductor resistance in the cables, especially where thinner conductors are used in flexible cables for rotating or moving platforms. -
Page 38: Permanent Mounting
The detector MUST be cooled via forced air cooling system. WARNING The 2315NDT has forced air cooling provided by fans, which run in the powered-on state. The air flowing through the detector is sufficient to cool the unit without relying on conductive or convective cooling provided that the air flows into the entrance fan from the outside of the X-ray housing, and is expelled such that it does not loop back into the fan inlet. -
