The CR3000 Micrologger® supports complex applications with many sensors. It is fast and powerful enough to handle extended eddy-covariance systems with full energy-balance systems. Multiple CR3000s can be configured as a network or units can be deployed individually.
Designed for stand-alone operation in harsh, remote environments. The CR3000 consists of a compact, integrated package with a built-in power supply, a 128-by-64-pixel backlit graphical or eight-line numeric display, and a 16-character keyboard.
Benefits and Features
Ideal applications include eddy covariance, wind profiling, HVAC, weather stations, vehicle testing, air quality, process control, mesonet systems, agriculture, soil moisture, time-domain reflectometry, water quality
Integrated keyboard and display screen let you program, manually initiate data transfers, and view data, all on site.
Includes a current excitation channel allowing direct connection of PRTs or other sensors that use a current excitation
Serial communications with serial sensors and devices supported via I/O port pairs
Supports PakBus, Modbus, SDI-12, and DNP3 protocols
Communicates via various options: TCP/IP, email, FTP, web server.
Gas Discharge Tube (GDT) protected inputs
4-MB memory can be expanded with add-on memory systems.
Flexible power and communication options make it ideal for remote locations.
Compatible with channel expansion peripherals allowing you to expand your system
Battery-backed SRAM and clock that ensure data, programs, and accurate time are maintained while datalogger is disconnected from the main power source
Contains custom ASIC chip that expands pulse count, control port, and serial communications capabilities
Program with LoggerNet, PC400, or ShortCut to fit your setup.
Collects and stores data and controls peripherals as the brain of your system
