Campbell Scientific CR1000 data loggers

The CR1000 measurement and control module replaces the CR10 series data logger and is suitable for long-term, remote deployment under a wide range of applications and industries, including the environmental, hydrological, mining and geotechnical sectors.

With 2 Mb of memory standard, and a 4 Mb option available, users can further expand it to 1 Gb of storage with the CFM100 CompactFlash module.

A custom-designed ASIC (application specific integrated circuit) adds functionality to the logger while reducing board space and components. The ASIC controls measurement sequence and timing, freeing the CPU for faster processing and data storage. With a nine pin CS I/O port, RS232 serial communications port and eight digital I/O terminals which can be configured to create four communications ports, the unit has a program execution rate of 100 Hz increasing up to 1500 Hz in burst mode. The communication ports are capable of speeds from 300 to 115,200 baud, facilitating data collecting from 'smart sensors', communicating between data loggers, and connecting to modems or network links.

The logger is compatible with the full range of peripherals and communications devices and features the PakBus operating system - a packet switched communications protocol which facilitates data logger networking. The logger also incorporates the CRBasic programming language. Loosely based on the familiar BASIC programming language, CRBasic combines the user-friendliness of a commercial programming language with the power of the CR1000 hardware.
