Chúng tôi xin giới thiệu tới quý khách sản phẩm bộ thu thập và xử lý dữ liệu CR500 Datalogger Campbell Sientific

The CR850 is a smaller, research-grade datalogger that includes an on-board keyboard display as part of its integrated package. It is intended for smaller configurations in which fewer sensors will be measured. Each CR850 reads input from sensors, then transmits the data via a communication peripheral; most sensors and telecommunication devices are compatible. Multiple CR850s can be configured as a network or units can be deployed individually. This rugged datalogger can provide stand-alone operation in harsh, remote environments.

Benefits and Features

• 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 SRAM and clock that ensure data, programs, and accurate time are maintained while datalogger is disconnected from the main power source
• Program with LoggerNet, PC400, or ShortCut to fit your setup.

Technical Description

The CR850 consists of measurement electronics encased in a plastic shell with an integrated wiring panel, 16- character keyboard, and display screen. The display can show 8 lines x 21 characters (64 x 128 pixels). Custom menus are supported allowing customers to set up choices within the datalogger program that can be initiated by a simple “toggle” or “pick list”. Its keyboard and display screen is used to program the datalogger, manually initiate data transfer, and display data.

The CR850 uses an external  power supply. Low power consumption allows the it to operate for extended time periods on a battery recharged with a solar panel—eliminating the need for AC power. The CR850 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.
