陶瓷隔膜真空计

CCMT-D 系列

CCMT-100D

アルバック

CCMT-D系列、陶瓷隔膜根据气体的压力变化发生变形、电容式真空计根据静电容量的变化检测压力。
传感器部由陶瓷一体构造,具备优秀的再现性、稳定性,在低·中真空领域不受气体的种类影响(可以测量绝对压力),能够高精度地测量。

特点

  • 长期稳定
  • 使用陶瓷膜,具有优异的耐腐蚀性
  • 内置式温度补偿回路
  • 采用新结构保护传感器免受污垢
  • 可以通过按钮进行零点调整

用途

  • 用于成膜设备工艺中的压力监控
  • 用于真空溶解、真空热处理炉等真空排气系统的压力监控
  • 用于太阳能电池等各种制造设备的压力监控
