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。

Additional Compatibility Information

Sensors

With several channel types, the CR850 is compatible with nearly every available sensor, including thermocouples, SDI-12 sensors, and 4 to 20 mA sensors. A custom ASIC chip expands its pulse count, control port, and serial communications capabilities. The CR850's I/O ports can be paired as transmit and receive, allowing serial communications with serial sensors and devices.

Measurement & Control Peripherals

The CR850 is compatible with all of our CDMs (requires an SC-CPI), SDMs, multiplexers, vibrating-wire interfaces, terminal input modules, and relays. 

Communications

The CR850 communicates with a PC via direct connect, NL201 Ethernet Interface, multidrop modems, short haul modems, phone modems (land line, digital cellular, and voice-synthesized), RF telemetry, and satellite transmitters (Argos and High Data Rate GOES).

Data can be viewed on its onboard keyboard display, CD100 Mountable Display with Keypad, user-supplied iOS or Android device (requires LoggerLink), CD295 DataView II Display, or a user-supplied PDA (PConnect or PConnectCE software required).

The SC115 is the only compatible external data storage device. The CR850 does not have a peripheral port and is therefore not compatible with the CFM100, NL115, or NL120.

Enclosures

The CR850 and its power supply can be housed in any of our standard enclosures. 

Power

Any 12 Vdc source can power the CR850 datalogger. Power supplies commonly used with the CR850 are the BPALK, PS100, and PS200. The BPALK provides eight non-rechargeable D-cell alkaline batteries with a 7.5 A h rating at 20°C.

Both the PS100 and PS200 consist of a sealed rechargeable 7 A h battery and a charging regulator. Their battery should be connected to a charging source (either a wall charger or solar panel). These two power supplies differ in their charging regulator. The PS100 has a standard regulator and the PS200 has a micro-controller-based smart regulator. The PS200's regulator provides two-step constant voltage charging and temperature compensation that optimize battery charging and increases the battery’s life.

Also available are the BP12 and BP24 battery packs, which provide nominal ratings of 12 and 24 A h, respectively. These batteries should be connected to a regulated charging source (e.g., a CH100 or CH200 connected to a unregulated solar panel or wall charger).

Software

CRBasic, the CR850's full programming language, supports simple or complex programming and many onboard data reduction processes.

下载

CR800 OS v.32.03 (4.86 MB) 13-08-2018

Execution of this download installs the CR800 Operating System and Compiler on your computer.  It also updates the CR800 support files for the CRBasic Editor.  

Note: This OS has crossed the 2 Meg CR800 size limit for remote download.  The OS must be downloaded to the 2 Meg CR800 via direct connect with the Device Configuration Utility.  All OS download methods are supported by the 4 Meg CR800.

Upgrading from versions prior to version 28 of the Operating System will reset the datalogger’s CPU drive.  This is due to a change in the format of the file system from FAT16 to FAT32.  In order for the datalogger to operate correctly, as part of the upgrade, the CPU drive is formatted to FAT32.  Any programs stored and running from the CPU drive will be lost.  It is not recommended to update the datalogger’s Operating System over a remote connection where program control regulates the communication equipment (turning it on or off, etc.).  In these cases, an on-site visit and a backup using DevConfig’s backup utility is necessary to update the datalogger’s Operating System.

Watch the Video Tutorial: Sending an OS to a Local Datalogger.

In all cases where the datalogger is being updated from an Operating System prior to 28, the use of DevConfig’s backup utility is recommended due to the CPU drive being formatted using the new FAT32 format.

常见问题解答

CR850: 146

展开全部收起全部

  1. Yes, using the DisplayMenu/EndMenu() and MenuItem instructions.
  2. No. The display has its own OS that is not programmable using CRBasic.
  3. Yes. The CR800 and CR850 are compatible with exactly the same options as the CR1000 but with a lower channel count.

  4. No. A device is needed that can convert fiber optic to RS-232. Many customers have used products from B&B Electronics for this purpose.
  5. The data logger can store multiple programs; however, one program is capable of supporting all sensors simultaneously. A dedicated program for each sensor is unnecessary and would not be practical to implement.

  6. Use the CURS100 device or a precision 100 ohm resistor to make 4 to 20 mA measurements.

  7. Calibration is recommended every two years.
