Campbell Scientific, a maker of research-grade measurement instruments, is releasing an innovative new line of data-acquisition products: the CR300-series measurement and control dataloggers. The CR300 dataloggers have many of the best capabilities of full-size Campbell Scientific dataloggers, with the smaller size and price of Campbell’s compact devices.
The CR300 dataloggers offer faster communications, low power requirements, built-in USB, and excellent analog input accuracy and resolution. The newest CR310 addition is ideal for machine-to-machine and Internet of things applications.
“A nice part about the CR300 is that, from a user’s skill-level standpoint, it is not so different from our other dataloggers, so the learning curve is very small,” said Kevin Rhodes, Product Manager for the CR300. “Integrators can capitalize on their knowledge of CRBasic and our other popular dataloggers for use with this lower-cost datalogger.”
The CR300 was developed based on customer feedback, especially from those who already embed Campbell Scientific dataloggers in their own products. It is a step up from Campbell’s earlier low-cost, compact dataloggers because of its much richer CRBasic command set and serial communication capabilities, and its capacity for larger, more complex programs. The CR300 also has its own onboard compiler that can handle large, complex programs.
The CR310 is the newest addition to the CR300 series and has the same capabilities of the CR300 datalogger, with the addition of removable connectors and an integrated 10/100 Ethernet connection.
The integrated Ethernet interface makes the CR310 ideal for machine-to-machine (M2M) and Internet-of-things (IoT) applications requiring internet-connected remote monitoring and control. Simple connection to external wireless devices enables remote communication with satellite, cellular, and licensed radios.
The CR310 is also available with optional integrated WiFi and license free radios for wireless networking. Providing complete compatibility with a variety of measurement and communication protocols, the CR310 supports TCP/IP, Modbus, DNP3, SDI-12, HTTP, FTP, and email.
The CR300 series dataloggers are the same size as the earlier compact Campbell Scientific dataloggers, so they can be drop-in replacements. They are also the first Campbell dataloggers that can measure 4 to 20 mA sensors natively. It has a 24-bit analog to digital converter, a high-speed processor, and a micro-USB port. For communication, the CR300 has full PakBus capability, making it an important part of your network. There is plenty of non-volatile flash memory for storage.
The CR300 series dataloggers are programmed with Campbell Scientific’s LoggerNet software, which includes a point-and-click program generator, and a network planner for graphical layout of devices.
