Campbell Scientific, a maker of research-grade measurement instruments for over 40 years, is releasing a 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 dataloggers.
Kevin Rhodes, product manager for the CR300, said, “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. Integrators can capitalize on their knowledge of CRBasic and our other popular dataloggers for use with this lower-cost datalogger.”
The CR300 datalogger was developed based on customer feedback, especially from customers who 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 CR310 includes an integrated Ethernet interface, making it 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 Wi-Fi 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.
The CR300 series is the best-value line of dataloggers Campbell Scientific has ever built. 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.
Campbell Scientific’s history of developing innovative products began in the 1970s, as one of the first to offer low-power, high-precision dataloggers for use in the field. The company has developed increasingly powerful dataloggers to satisfy customers’ measurement needs. To date, Campbell Scientific has manufactured more than 300,000 dataloggers.
EE181 temperature and humidity probe
Campbell Scientific is also now offering the accurate, rugged EE181 air-temperature and relative-humidity (RH) probe. It is ideal for low-power, unattended applications requiring outstanding long-term stability and reliability.
The EE181 features a steel-mesh filter and a proprietary coating on the RH element, which increases the life of the element and protects it from dirt, dust, salt, or other contaminants. Excellent results from ongoing field testing worldwide confirm this research-grade instrument is ready for deployment in the harshest environments. The EE181 is compatible with all Campbell Scientific dataloggers, including the new CR300 series.
