Overview

The CR295X is a small, low-cost datalogger 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.

Benefits and Features

  • Small, low-cost datalogger 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 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 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 tab for compatible sensors, peripherals, and software). Recalibration services are not offered for the CR295X dataloggers.

Additional Compatibility Information

Communications

The CR295X is compatible with our TX320, TX312 (retired), and SAT HDR GOES (retired) satellite transmitters.

The CR295X can communicate with a PC via direct connect, NL201 Network Link Interface, NL240 Wi-Fi Network Link, MD485 multidrop modem, and digital cellular modems. Data can be viewed on an iOS device, an Android device, CD295 DataView II Display, or a user-supplied PDA. To use an iOS or Android device, go to the Apple Store or Google Play and download our LoggerLink Mobile Apps free of charge. User-supplied PDAs require either PConnect or PConnectCE software.

Measurement & Control Peripherals

Campbell Scientific’s SDM devices and multiplexers are not supported.

Power Supplies

Typical power supply is a BP12 12 Ahr or BP24 24 Ahr battery, CH100 or CH200 regulator, and an SP10 or SP20 solar panel. The CR295X includes a cable for connecting it with the satellite transmitter and power supply.

Enclosures

An ENC16/18 enclosure can house the CR295X logger, satellite transmitter, and power supply; smaller enclosures cannot house the power supply required for GOES communications. Hardware is included with the datalogger for mounting to an enclosure backplate.

Sensors

The CR295X can measure a variety of sensors including SDI-12 sensors and 4 to 20 mA sensors. It cannot make differential measurements and is not compatible with the freezing-rain/ice, fuel moisture/temperature, geographic position, present weather, soil heat flux, soil matric water potential, and strain sensors listed on our price lists.
