300kV Portable Industrial NDT X-Ray Imaging System

Spellman’s LPX Series are perfectly suited for today’s demanding NDT inspection requirements. LPX units are rugged, yet easy to transport and economical to maintain. They can be line or portable generator powered automati­cally adapting to standard input voltages to permit all day inspection under extreme conditions virtually anywhere.


The end grounded X-Ray tubes have a focal spot size of 1.5mm sq and the exposed anode allows for easy and flexible positioning of the tube head assembly. Tube ports use a low-absorption beryllium window that allows the radiographer to utilize the full spectrum of X-Ray energy. The high radiation output of the LPX systems allow for lower kV per exposure, shorter exposure times and increased film contrast for superior radiographic imaging.


The LPX microprocessor-driven control unit provides automatic warm-up and comprehensive self-diagnostic circuitry. Memory to store and recall up to 250 exposure techniques is standard and the last set of exposure para­meters is retained before powering down. The LPX is adjustable in 1kV and 0.1mA increments. Exposure dura­tion can be set from 1 second to 99 min 59 seconds in 1 second increments; mAs is variable from 0 to 29995 mAs.

Typical applications:

  • Aerospace
  • Manufacturing
  • Defense
  • Aviation
  • Energy
  • Security Systems
  • NDT Applications

 Laser Pointer

LPX300 Industrial NDT X-Ray System (Image 3)Spellman’s exclusive Laser Pointer allows pinpoint image area targeting. The Laser Pointer projects a highly visible reference laser beam from the tubehead to surfaces up to 75 feet away, showing precisely where the central X-Ray beam will be located, providing unmatched accuracy for greater efficiency and reduced set-up times.

 Model 1620 Tubehead Stand

LPX300 Industrial NDT X-Ray System (Image 4)An optional X-Ray Tubehead Stand allows for quick set up and provides rigid support for optimal image quality with three-axis positioning of the tube-head assembly. The stand incorporates telescoping legs, a hand wheel-dri­ven variable height adjustment and lockable hand wheel controlling the tubehead tilt and horizontal rotation. The tubehead cradle is cushioned for secure mounting and vibration damping. A bubble-type indicator is included for quick and easy leveling of the tubehead. Black anodized aluminum construction. 35lbs. (16kg) approx.

 Optional Air Cooled Tube Head Assembly

LPX300 Industrial NDT X-Ray System (Image 5)The air cooled tube head assembly uses a heat sink and high volume fan to dissipate heat from the anode and typically is used in applications that do not have limited access and are not in a volatile fuel vapor atmosphere. The air cooled tube head assembly does not require the cooler unit and the associated mixing and maintenance of liquid coolant. This unit requires less user maintenance and could be consid­ered more environmentally friendly.
