Technische Beschreibung

Der CR800 und der CR850 ermöglichen präzise Messungen verschiedenster Sensoren. Beide Modelle bestehen aus der Messelektronik in einem Metallgehäuse, integriert in eine Anschlussleiste aus Kunststoff. Der CR850 enthält ein eingebautes Display und eine Tastatur zur direkten Datenanzeige. Der CR800 kann mit einem externen Keyboard Display, dem CR1000KD, über den CS I/O-Port verbunden werden. Das Auslesen der Daten per Laptop oder PDA über die RS232 Schnittstelle oder über Funk,- Festnetz- oder GSM-Modem ist natürlich bei beiden Modellen möglich. Der CR800/CR850 ist PakBus-kompatibel und kann damit ein Bestandteil von Netzwerken sein.

Der Logger wird über CR-BASIC programmiert, eine BASIC-ähnliche Programmiersprache, für einfache Anwendungen reicht auch der freie visuelle Editor Shortcut. Darin enthalten sind Messbefehle für Brückenmessungen, Spannungsmessungen, Thermoelemente und Puls/Frequenzmessungen. Datenverarbeitung im Logger kann über algebraische, transzendente und statistische Funktionen erfolgen. Außerdem werden die Daten gespeichert und es können externe Geräte kontrolliert werden.

Additional Compatibility Information

Sensors

With several channel types, the CR800 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 CR800's I/O ports can be paired as transmit and receive, allowing serial communications with serial sensors and devices.

Measurement and Control Peripherals

The CR800 is compatible with all of our CDMs (requires an SC-CPI), SDMs, multiplexers, vibrating-wire interfaces, terminal input modules, and relays. 

Communications

The CR800 communicates with a PC via direct connect, NL201 Ethernet Interface, multidrop modems, phone modems (land line, digital cellular, and voice-synthesized), RF telemetry, and satellite transmitters (Argos, Iridium, and Inmarsat.

Data can be viewed on the CR1000KD 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 CR800 does not have a peripheral port and is therefore not compatible with the CFM100, NL115, or NL120.

Enclosures

The CR800 and its power supply can be housed in any of our standard enclosures. 

Power

Any 12 Vdc source can power the CR800 datalogger. Power supplies commonly used with the CR800 are the BPALK, PS150, and PS200. The BPALK provides eight non-rechargeable D-cell alkaline batteries with a 7.5 A h rating at 20°C.

Both the PS150 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 PS150 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 CR800's full programming language, supports simple or complex programming and many onboard data reduction processes.

Downloads

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.

Alle anzeigenWenige anzeigen

  1. The datalogger 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.
  2. The 5 V terminal is regulated and remains near 5 Vdc (±4%) as long as the CR800 supply voltage remains above 9.6 Vdc. Measurement of the output from 5 V (by means of jumpering to an analog input on the same CR800) enables an accurate bridge measurement if the 5 V terminal must be used for excitation.

  3. Yes, but it is difficult and time consuming. The display is best used to make small changes in an existing program already installed in the datalogger.
  4. Yes. The CR800 and CR850 are compatible with exactly the same options as the CR1000 but with a lower channel count.

  5. Baler 2.2 was developed before the release of the CR800 and, therefore, does not work with it.The latest version of Baler does work with the CR800 and can be found in the Downloads section of the Baler product page.

    Note: As newer versions of Baler are released, upgrades to older versions may not work. The notes associated with the upgrade or patch indicate which previous version needs to be installed before installing the upgrade.

  6. Yes. Many customers use the Iridium satellite transceiver.
  7. Calibration is recommended every two years.
