Überblick

Der CR300 ist ein kleiner Datenlogger mit modernster Technik. Optisch ähnlich dem CR200X enthält er einen besseren AD-Wandler, Differentialkanäle mit excellenter Auflösung, USB-Port, 10MB Speicher und die Möglichkeit, 4-20mA direkt zu messen.  

Damit können fast alle meteorologischen, hydrologischen und industriellen Sensoren angeschlossen werden. die Daten können dann über verschiedene Netzwerke und Kommunikationsoptionen zugänglich gemacht werden.

Den CR300 gibt es mit verschiedenen Kommunikationsoptionen wie  WiFi, Mobilfunk und Funk für unterschiedliche Regionen:

    • CR300-RF407: USA und Kanada
    • CR300-RF412: Australien und Neuseeland
    • CR300-RF422: Europa

Bitte beachten Sie: Campbell Scientific empfiehlt den CR300 nicht als PakBus Router in Netzwerken mit mehr als 50 Geräten. Bei großen Feldern oder String Variablen kann der Speicher nicht ausreichen. Für solche Fälle ist der CR1000X besser geeignet.

Technische Beschreibung

The CR300 is a low-powered data logger designed to measure sensors, analyze data, and store data and programs. A battery-backed clock assures accurate timekeeping. The on-board, BASIC-like programming language—common to all Campbell Scientific data loggers—supports data processing and analysis routines.

The CR300 wiring panel includes a switchable 12 V terminal, and analog grounds dispersed among six analog terminals.

Additional Compatibility Information

Sensors

With several channel types, the CR300 is compatible with nearly every available sensor. This includes analog output voltage (0 to 2.5 V) and current (0 to 20 mA or 4 to 20 mA) sensors, thermistors, and RTDs to name a few. It is also compatible with pulse or frequency output sensors such as anemometers, rain gauges, and flow meters. CR300 dataloggers are not capable of applying reverse excitation, and they cannot be used with some conductivity or soil matric potential sensors.

SDI-12, Modbus, and other serial sensors are supported with the RS-232 port and C1 and C2 as a Tx/Rx pair. The CR300 does not directly support RS-485 sensors.

Measurement & Control Peripherals

The CR300 is compatible with low current and voltage solid-statey relays but not with SDM or CDM devices.

Communications

The CR300 can communicate with a PC directly via its USB port. Compatible telemetry devices include our RS-485 converters, digital cellular gateways, RF telemetry, and satellite transmitters (HDR GOES, Argos, Meteosat, Iridium, and Inmarsat). Data can be viewed on an iOS or Android device (requires our free LoggerLink app), CD295 DataView II Display, or other third-party devices.

Power

The CR300 uses an external power source and has a built-in charger/regulator. Intelligent power sourcing autoselects the highest voltage from three input sources (CHG, BAT, or USB) to operate in one of the following four modes:

  • UPS (recommended) - A 16 to 32 Vdc source, solar panel (SP10, SP20), or power converter (29796) is used to charge a 12 Vdc battery, such as our BP7 or BP12.
  • 12 Vdc battery or other reliable 12 Vdc source
  • Charge only - DC power supply (16 to 32 Vdc)
  • USB - Powered over 5 Vdc USB port for setup, programming, and testing (will not charge battery or boost USB power to provide 12 Vdc to the switched battery terminal SW12)

Software

The CR300 series is compatible with CRBasic (version 3.6 or higher).

Enclosures

An ENC10/12 or ENC12/14 enclosure is adequate for most CR300-based systems. Applications with minimal power requirements can use the ENC200 enclosure to house the CR300 and the 16869 Sealed Rechargeable Battery. The ENC200 cannot house a barometer or a battery that is larger than the 16869.
