Campbell Scientific's CR3000 Micrologger® - Our Newest Datalogger

LOGAN, Utah (October 1, 2005) - Campbell Scientific's CR3000 Micrologger® builds on the company's reputation for rugged and reliable measurement and control instrumentation. It retains the versatility of its predecessor, the CR23X Micrologger®, yet provides increased memory, faster processing, more measurement channels, and more telemetry options. A CR3000 Micrologger is housed in a portable, self-contained package that consists of measurement and control electronics, communication ports, keyboard, graphical or 8-line numeric display, 5V or 12V power supply, and a peripheral port for a CompactFlash® card. Having more options allows for flexibility of retrieving and analyzing data for industrial applications.

Most commercial sensors can be measured with the versatile assortment of channels consisting of 28 single-ended or 14 differential analog inputs (individually configured), four 24-bit pulse counters, four switched voltage and three switched current outputs for excitation, and eight control/digital ports. Multiple SDMs (Synchronous Devices for Measurement) can be connected to one CR3000 datalogger to add control ports, analog outputs, pulse count channels, interval timers, or even a CANbus interface to your system. An RS-232 port and CS I/O port facilitate multiple telemetry options for the datalogger via radio, satellite, phone (land line and cellular), Ethernet, and more.

The design of the CR3000 allows flexibility in long-term, unattended monitoring at remote sites or within network applications. The datalogger uses minimal power, from such sources as rechargeable batteries, a vehicle battery, AC power, or even solar panels. The CR3000 stores approximately 4 MB data values internally, and with the CFM100 module and a CompactFlash® card, stores up to 2 Gigabytes externally.

Campbell Scientific, Inc. is a world-wide manufacturer of dataloggers, data acquisition systems, and measurement and control products. To learn more about the CR3000 and to obtain detailed specifications, please visit
