Campbell Scientific CR1000 Datalogger

Campbell Scientific CR1000 er Campbells mest brukte datalogger. Den kan brukes til et bredt spekter av måle- og styrefunksjoner. Loggeren er pålitelig og robust, godt egnet for avsidesliggende installasjoner og kraftig nok til å håndtere komplekse konfigurasjoner.

  • Ideell for bruksområder som omhandler blant annet værstasjoner, vindprofilering, jordfuktighet, vannstand, vannkvalitet mm.
  • Støtter et bredt spekter av kommunikasjonsprotokoller inkludert PakBus, Modbus, SDI-12 og DNP3
  • Fleksible strøm- og kommunikasjonsmuligheter gjør den ideell for avsidesliggende steder

Description

Overview

The CR1000 is Campbell Scientific’s most widely used data logger. It can be used in a broad range of measurement and control functions. Rugged enough for extreme conditions and reliable enough for remote environments, it is also robust enough for complex configurations.

The CR1000 builds on the foundation of the CR10X data loggers and has already been put to use all over the world. Increased memory and more measurement channels make it a powerful core component for your data-acquisition system.

Technical Description

The CR1000 consists of a measurement and control module and a wiring panel. This data logger uses an external keyboard/display and power supply. Low power consumption allows the CR1000 to operate for extended time periods on a battery recharged with a solar panel&mdasheliminating the need for AC power. The CR1000 suspends execution when primary power drops below 9,6 V, reducing the possibility of inaccurate measurements.

The CR1000's module measures sensors, drives direct communications and telecommunications, reduces data, controls external devices, and stores data and programs in on-board, non-volatile storage. The electronics are RF shielded and glitch protected by the sealed, stainless-steel canister. A battery-backed clock assures accurate timekeeping. The module can simultaneously provide measurement and communication functions. The on-board, BASIC-like programming language supports data processing and analysis routines.

The CR1000WP is a black, anodized aluminum wiring panel that is compatible with all CR1000 modules. The wiring panel includes switchable 12 V, redistributed analog grounds (dispersed among analog channels rather than grouped), unpluggable terminal block for 12 V connections, gas-tube spark gaps, and 12 V supply on pin 8 to power our COM-series phone modems and other peripherals. The control module easily disconnects from the wiring panel allowing field replacement without rewiring the sensors.

Originally, the standard CR1000 had 2 MB of data/program storage, and an optional version, the CR1000-4M, had 4 MB of memory. In September 2007, the standard CR1000 started having 4 MB of memory, making the CR1000-4M obsolete. Data loggers that have a module with a serial number greater than or equal to 11832 will have a 4 MB memory. The 4 MB data loggers will also have a sticker on the canister stating “4M Memory”.
