概览

CR7是高精密的设备,主要用于多参数研究和工业应用中。每一个CR7都单独地设置,以符合客户指定的测量要求。

CR7X控制模块是整个测量系统的基础,再加入输入/输出模块、数据采集器机箱和I/O卡。由于不同的研究之间的测量要求会有变化,CR7可以适用这些变化,更改I/O卡的设置。

  • 特别适合要求高精度(例如:热电偶)或大数目输入通道的应用。
  • 最多可插入7个(CR7 720)I/O卡,或14个(CR7 720XL)I/O卡,为特定的应用配置一个系统。
  • 可存储280,000个数据点
  • 模块化的设计,包括:
    • 控制模块(CR7 700X)
    • 输入/输出模块(CR7 720 或 CR7 720XL)
    • 野外版或实验室版机箱(ENC 7F,ENC 7XL,ENC 7L)
  • 24 KB ROM内存,40 KB RAM内存
  • 所存储的数据格式为混合数组
  • 支持软件:LoggerNet(功能齐全)或 Short Cut (仅编程)

技术说明

CR700X控制模块是CR7大型模块化数据采集器的主要组件。订购时含内部PROMs(固件)和温度测试。CR700X包含系统的CPU、ROM、RAM、与数据存储/收集外设进行通讯的串行接口、最多可接4个I/O模块的连接接口(通常一个模块紧挨着CR700X一侧,另外三个模块距离CR700X一定距离)、还有一个键盘显示器。请参阅设置标签查看软件兼容性。

CR700X还可容纳:

  • PROMs (在订购信息标签下有详细信息)
  • 3259 电池(已含;以前被称作LA700)
  • CR709 内存卡(单独订购)

完整的CR7包括:

  • CR700X
  • I/O 模块(CR720,或者CR720XL)
  • 多种I/O卡的混合组合

常见问题解答

CR700X: 1

  1. A practical maximum is to connect one multiplexer per every two control terminals on the data logger. Control terminals can be shared between multiplexers to increase the number of connected multiplexers. Sharing terminals, however, requires more complex wiring and programming. Users who would like to connect more than one multiplexer per every two control terminals are advised to contact a sales or support engineer at Campbell Scientific for assistance.
