Overview

CR295X GOES Datalogger (-40 to +50C)

The CR295X is a small, low-cost data logger that reads input from one or two sensors, then transmits the data using the GOES satellite transmitter. Multiple CR295Xs can be configured as a network, or units can be deployed individually. CRBasic, its full programming language, supports simple or complex programming and many onboard data reduction processes. It supports stand-alone operation in harsh, remote environments.

Key Advantages

Lowest-Cost Data Logger for Use With Satellite
Good for SDI-12 measurements

Technical Description

The CR295X includes an additional RS-232 serial port that allows communications with the TX320, TX312, or SAT HDR GOES satellite transmitter. It has several input channels for measuring a variety of sensors. Gas discharge tubes provide rugged electrostatic discharge protection for the inputs.

The CR295X does not make differential measurements and is not compatible with SDM devices, multiplexers, or thermocouples. (Refer to the Compatibility information on the web page for compatible sensors, peripherals, and software.) Recalibration services are not offered for the CR295X dataloggers.

Benefits

  • Small, low-cost data logger designed for use with GOES satellite transmitters
  • When combined with the TX320 GOES satellite transmitter, the CR295X can be used in extremely remote locations.
  • 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 data logger is disconnected from battery power
  • Program with LoggerNet, PC400, or Short Cut to fit your setup
  • PakBus, Modbus, and SDI-12 protocols supported
