Bộ thu thập và lưu trữ dữ liệu Campbell Scientific Datalogger CR200X


The CR200X, our smallest lowest-cost datalogger, provides stand-alone operation in harsh, remote environments. It reads input from one or two sensors, then transmits the data using communication peripherals. CRBasic, its full programming language, supports simple or complex programming. Multiple CR200Xs can be configured as a network, or units can be deployed individually.

Benefits and Features

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

  • Campbell Scientific’s smallest, lowest cost datalogger

  • 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 CR200X has several input channels for measuring a variety of sensors. Gas discharge tubes provide rugged electrostatic discharge protection for the inputs.

The CR200X 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 CR200X datalogger.
