Overview
The CR295 GOES Datalogger includes an additional 9-pin serial port that allows communications with a TX312 or the retired SAT HDR GOES satellite transmitter. Its single-ended input channel configuration and packaging are optimal for measuring one or two simple sensors. However, the CR295 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 CR200-series dataloggers.

Sensors
The CR295 cannot make differential measurements and is not compatible with thermocouples, our geographic position sensor, fuel moisture/temperature probe, and soil heat flux sensors. However, it can measure a variety of sensors including SDI-12 sensors and 4 to 20 mA sensors. Our CS625 Reflectometer, 109 Thermistor, and CS15 Electric Current Sensor were specifically developed for our CR200-series dataloggers. Other compatible sensors include wind sets, tipping buckets, and barometers. For a complete list of compatible sensors, see the CR200-series brochure.
Communications
The CR295 is compatible with the TX312 HDR GOES Satellite transmitter and the SAT HDR GOES Satellite Transmitter (retired). It can communicate with a PC via direct connect, NL100 Ethernet Interface, MD485 multidrop modem, and our digital cellular modems. Data can be viewed on the CD295 DataView II display or a PDA (PConnect or PConnectCE software required).
Power Supply
Typical power supply is a BP12 12 Ahr or BP24 24 Ahr battery, CH100 regulator, and an SP10 or SP20 solar panel. The CR295 includes a cable for connecting it with the satellite transmitter and power supply.
Use in Enclosures
An ENC16/18 enclosure can house the CR295 logger, satellite transmitter, and power supply; smaller enclosures cannot house the power supply required for GOES communications. Hardware is included with the logger for mounting to an enclosure backplate.

Frequently Asked Questions
Number of FAQs related to CR295: 1
-
A practical maximum is to connect one multiplexer per every two control terminals on the data logger. Control terminals can be shared between multiplexers to increase the number of connected multiplexers. Sharing terminals, however, requires more complex wiring and programming. Users who would like to connect more than one multiplexer per every two control terminals are advised to contact a sales or support engineer at Campbell Scientific for assistance.
