顺序波长色散X射线光谱仪WDX-4000是一种顺序式波长色散X射线光谱仪,广泛应用于地质,水泥,钢铁,环保等领域。特别适合用于大中型企业产品生产质量检测和控制。
顺序波长色散X射线光谱仪WDX-4000主要特点：
的测角仪的设计
●创新和火成钢皮带传动系统。这种的设计提供了无摩擦，没有反弹，稳定的运动，保证确的角度定位。
●8/28轴有独立的驱动系统和伺服电机编码器反馈
●永磁同步电机（PMSM）提供、最平稳的运动
●光学编码器0.0001°分辨率和0.0006°精度保证集成系统达到优良的性能。
多通道分析仪
●12位，80msps，大的AD采样系统、完整、准确地记录信号
●4096（12bit）通道分析仪基于高速FPGA架构和强大的DSP算法能够区分正确的X射线从噪声和杂散光
●能量色散作用是额外的。
ray Tube高压发生器
●标准功率kw系统给出了痕量元素的分析灵敏度和较高速度的分析
●薄铍窗（50um或75um）提供了X射线超传输，特别是低能量区
●60kV及140ma，（75kv 150mA是可选的）和灵活的设置有助于更精细的分析方法
●双循环水冷却系统，去离子水的电导率保持比1us由管寿命的树脂增加尽可能低的多。
