cr1000x介绍 : 新一代功能可靠的数据采集器

正如我们的预期 CR1000 (发布于2004年) 是一款非常成功的数据采集器。已经销售了近100,000台, 安装在地球的每一个大陆。Campbell Scientific利用CR1000的成功设计, 同时集成了CR6(发布于2014年) 的很多元素, 推出了CR1000X. CR1000X融合了以上两款产品的优点。 CR1000X 数据采集器可以应用在哪些地方? 对数据采集器的初学者而言,CR1000X是一款低功率的设备,广泛应用于数据测量,存储和控制。CR1000X的可靠性和坚固程度使它成为远程环境应用(数据完整性至关重要)的最佳选择,比如气象站,中尺度气象网,风廓线,空气质量监测,水文系统,水质监测,水文气象站等。 CR1000X带来了哪些帮助? 以下是CR1000X给我们带来的7大帮助: 可以通过网页浏览器连接CR1000X 页面设计简单,便于浏览实时记录数据。 用户可以快速方便的更换掉已有的CR1000 CR1000X的结构设计延续了CR1000的特点, 同时又增加了可拆卸端子的功能。 CR1000X的集成功能降低了整个监控系统的成本 CR1000X集成了CR1000常用的几种扩展设备: NL116连接以太网, SDM-SIO1A 扩展 RS-485, SC-CPI 连接Campbell Scientific设备扩展模块。 CR1000X在所有环境数据采集器中,具备最高的精度和分辨率 CR1000X提供了高精度模拟测量。 可以直连电流传感器 CR1000X具备电流测量功能(0 ~ 20 mA 或 4 ~ 20 mA), 无需外围设备。 CR1000X适用于极端环境 标准工作温度范围 -40 ~ +70°C 满足绝大多数应用。 对于极端环境, CR1000X也提供了可选的扩展工作温度-55° ~ +85°. CR1000X提供多种通信端口和可拆卸端子 可拆卸端子便于快速安装,... 阅读更多
