Overview
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.
Key Advantages
Supports complex installations, built-in keyboard and display
Technical Description
Housed in a portable, self-contained package, the CR3000 Micrologger® consists of measurement and control electronics, communication ports, 16-character keyboard, display, power supply, and carrying handle. The integrated display shows 8 lines x 21 characters (64 x 128 pixels).
The CR3000 has a choice of three power-supply base options (alkaline, rechargeable, or no battery). Low power consumption allows the Micrologger® to operate for extended time periods on its battery recharged with a solar panel—eliminating the need for AC power. It suspends execution when primary power drops below 9.6 V, reducing the possibility of inaccurate measurements.
The on-board operating system includes measurement, processing, and output instructions for programming the data logger. The programming language, CRBasic, uses a BASIC-like syntax. Measurement instructions specific to bridge configurations, voltage outputs, thermocouples, and pulse/frequency signals are included. Processing instructions support algebraic, statistical, and transcendental functions for on-site processing. Output instructions process data over time and control external devices.
Benefits
- 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
- Flexible power and communication options make it ideal for remote locations.
- Compatible with channel expansion peripherals allowing you to expand your system
- Battery-backed clock that ensures accurate time is maintained while data logger is disconnected from battery power
- Contains custom ASIC chip that expands pulse count, control port, and serial communications capabilities
- Program with LoggerNet, PC400, or Short Cut to fit your setup
- Collects and stores data and controls peripherals as the brain of your system
