Norma 301i-1719
Norma series automatic exposure control sensors can be used in the x-ray energy from 40kV to 150kV. The x-ray dose is accumulated through the ionization chambers and turn to the electrical signals. Then the signals are amplified by the pre-amplifier, and export to the x-ray system. Norma series have high sensitivity, low attenuation and good stability. The dimensions can be customized.
