CR850 Measurement and Control Data Collector with Keyboard Display

The CR850 data collector is a small research grade precision data collector that comes with a built-in keyboard display as part of an all-in-one package. Tend to support small applications that only measure a few sensors. Each CR850 reads the sensor readings and transmits the data through communication peripherals; Compatible with most sensors and communication devices. Multiple CR850s can be set up as a data collector network; Alternatively, numerous CR850 units can also be configured one by one. CR850 is sturdy and durable, and can work independently in harsh remote environments.

Integrated keyboard and display screen let you program, manually initiate data transfers, and view data, all on site.

Ideal applications include wind profiling, weather stations, ETo/agriculture, air quality, soil moisture, water level/stage, aquaculture, vehicle testing, Time Domain Reflectometry, SCADA, and water quality

Simpler in design, the CR800 and CR850 are easier to program and wire.

Serial communications with serial sensors and devices supported via I/O port pairs

Contains custom ASIC chip that expands pulse count, control port, and serial communications capabilities

Supports PakBus, Modbus, SDI-12, and DNP3 protocols

Compatible with channel expansion peripherals allowing you to expand your system

Includes both an CS I/O port and an RS-232 port for connecting communication devices

Gas Discharge Tube (GDT) protected inputs

Battery-backed clock that ensures accurate time is maintained while data logger is disconnected from battery power

Program with LoggerNet, PC400, or Short Cut to fit your setup

The CR850 includes a measurement control module with an integrated wiring panel enclosed in a plastic case, a 16 key keyboard, and an LCD display screen that can display 8-line 21 character numerical values (or 64x128 pixel graphics). Support custom menus, making it convenient for users to initialize the option settings function of the data collector program by simply switching or selecting a list. The integrated keyboard and display are used to start the working program of the data collector, initialize data transmission, and display data.

The CR850 uses an external keyboard display and power supply, and its extremely low power consumption allows it to be powered by a combination of small capacity rechargeable batteries and solar panels, eliminating the need for AC power. To reduce the possibility of inaccurate measurements, the CR850 will pause operation when the main power supply is below 9.6 V.

The internal operating system includes the measurement, processing, and output instructions required for programming the data collector. The programming language is CRBasic, using BASIC like syntax. Measurement instructions include: bridge setting, voltage output, thermocouple, pulse/frequency signal. The processing instructions include algebraic operations, statistics, and transcendental functions used for on-site processing. Output instructions to process data according to time periods or control external devices.
