CR3000 Micrologger

Product name：CR3000 Micrologger

Item：CR3000

Details：

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.

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 clock that ensures accurate time is maintained while datalogger 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

Detailed 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 datalogger. 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.

Compatibility

Sensors

With several channel types, the CR3000 is compatible with nearly every available sensor, including thermocouples, SDI-12 sensors, and 4 to 20 mA sensors. A custom ASIC chip expands its pulse count, control port, and serial communications capabilities. The CR3000's I/O ports can be paired as transmit and receive, allowing serial communications with serial sensors and devices.

Measurement & Control Peripherals

The CR3000 is compatible with all of our CDMs (requires an SC-CPI), SDMs, multiplexers, vibrating-wire interfaces, terminal input modules, and relays.

Communications

The CR3000 communicates with a PC via direct connect, Ethernet interfaces, multidrop modems, short-haul modems, phone modems (land line, digital cellular, and voice-synthesized), RF telemetry, and satellite transmitters (Argos, Iridium, and Inmarsat).

Data can be viewed on its onboard keyboard display, user-supplied iOS or Android device (requires LoggerLink), CD295 DataView II Display, or a user-supplied PDA (PConnect or PConnectCE software required).

Compatible external data storage devices are the CFM100, NL115, and SC115.

Enclosures

The CR3000 can be housed in an ENC12/14, ENC14/16, ENC16/18, ENC24/30, or ENC24/30S enclosure.

Power Supplies

The CR3000 is typically powered by its on-board alkaline or rechargeable power supply (see Ordering Info). When the rechargeable power supply is used, its internal 7 A h sealed rechargeable battery needs be charged via a vehicle (requires the DCDC18R), solar panel, or ac wall charger.

The CR3000 can also come with a low-profile base that requires a user-supplied dc source. It is preferred when the system’s power consumption needs a larger capacity battery or when it’s advantageous for the Micrologger to be thinner and lighter.

Software

CRBasic, the CR3000's full programming language, supports simple or complex programming and many on-board data reduction processes. Compatible software includes:
