概览
CR850数据采集器是小型的研究级精度的数据采集器,作为一体式套装的一部分,含有内置的键盘显示器。倾向支持只测量少数几个传感器的小型应用。每个CR850读取传感器的读数,再通过通讯外设传送数据;可兼容大多数传感器和通讯设备。多个CR850可以被设置成数据采集器网络;或者,众多CR850单元也可被逐个配置。CR850结实耐用,可在严酷的远程环境中独立工作。
优势与特点
Integrated keyboard and display screen let you program, manually initiate data transfers, and view data, all on site.
Ideal applications include wind profiling, weather stations, ETo/agriculture, air quality, soil moisture, water level/stage, aquaculture, vehicle testing, Time Domain Reflectometry, SCADA, and water quality
Simpler in design, the CR800 and CR850 are easier to program and wire.
Serial communications with serial sensors and devices supported via I/O port pairs
Contains custom ASIC chip that expands pulse count, control port, and serial communications capabilities
Supports PakBus, Modbus, SDI-12, and DNP3 protocols
Compatible with channel expansion peripherals allowing you to expand your system
Includes both an CS I/O port and an RS-232 port for connecting communication devices
Gas Discharge Tube (GDT) protected inputs
Battery-backed clock that ensures accurate time is maintained while data logger is disconnected from battery power
Program with LoggerNet, PC400, or Short Cut to fit your setup
技术说明
CR850包含封装在塑料壳内的带一体式接线面板的测量控制模块、16键的键盘、以及可显示8行21字符数值显示(或64x128像素绘图)的LCD显示屏。支持自定义菜单,方便用户通过简单切换或选取列表,来初始化数据采集器程序的选项设置功能。一体式的键盘和显示器用于启动数据采集器工作程序,初始化数据传输,显示数据。
CR850使用外部的键盘显示器和供电电源,极低的功耗使得CR850只需要使用小容量的可充电电池和太阳能板组合供电,从而不需要交流电源。为了减小非精确测量的可能性,当主电源低于 9.6 V时,CR850会暂停工作。
内部的操作系统包括数据采集器编程所需的测量、处理、输出指令。编程语言为CRBasic,使用类BASIC语法。测量指令包括:电桥设置、电压输出、热电偶、脉冲/频率信号。处理指令包括:代数运算、统计及用于现场处理的超越函数。输出指令按时间段处理数据,或控制外部设备。
