Bộ thu thập và lưu trữ dữ liệu Datalogger truyền thông radio 900 MHz Campbell Scientific CR206X 

Overview

The CR206X is a small, low-cost datalogger that includes an internal 900 MHz spread-spectrum radio for transmitting data to another CR206(X), an RF401(A) radio, or an RF430 radio. The 900 MHz frequency is used in the US and Canada.

The CR206X provides stand-alone operation in harsh, remote environments. It reads input from one or two sensors, then transmits its data wirelessly via its internal radio. Multiple CR206Xs can be configured as a network, or units can be deployed individually.

Benefits and Features

  • Small, low-cost datalogger with internal spread spectrum radio for wireless communications

  • Integrated radio lets this datalogger function like a wireless sensor in a network, transmitting to a master datalogger

  • Ideal applications include wind energy, rural water, water level/flow, aquaculture, water quality

  • Gas Discharge Tube (GDT) protected inputs

  • Optimal for measuring one or two simple sensors

  • Makes SDI-12, single-ended analog, pulse, switch closure, and bridge measurements

  • Battery-backed clock that ensures accurate time is maintained while datalogger is disconnected from battery power

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

  • PakBus, Modbus, and SDI-12 protocols supported

Detailed Description

The CR206X can be used in a wireless sensor network. Wireless sensor networks are appealing because they are often more economical than trenching, laying conduit, and pulling wire. When used as a wireless sensor, the CR206X measures the sensors attached to it, then transmits its data wirelessly via its spread-spectrum radio to a master datalogger. The master datalogger must support the PakBus communication protocol (e.g., CR800, CR850, CR1000, CR3000). For more information on how to configure a PakBus system, please read our PakBus Networking Guide.

The CR206X has several input channels for measuring a variety of sensors. Gas discharge tubes provide rugged electrostatic discharge protection for the inputs.

The CR206X does not make differential measurements and is not compatible with SDM devices, multiplexers, or thermocouples (refer to the Compatibility information for compatible sensors, peripherals, and software). Recalibration services are not offered for the CR206X datalogger.
