February 9, 2014. CAS DataLoggers and MadgeTech have partnered to introduce the new RFCurrent2000A Wireless Current Data Logger with display, designed to measure and record DC current signals. The data logger can connect directly to low-level DC current sources, which makes it suitable for photovoltaic (PV) research, battery usage studies, energy monitoring studies, and other DC current monitoring applications. Users can also interface these data loggers with a range of current output sensors such as flow meters and pH transmitters. Through the software, the device can be programmed to convert the current readings into a different unit of measure such as flow rate.
The instrument is available in a 20-mA, 160-mA, or a 3-A measurement range. It features an LCD that provides instant access to the current reading as well as minimum, maximum, and average statistics. The screen also has a battery life indicator (battery life is 4 years at a 15-minute sampling rate). The statistics can be reset through the data logger’s keypad, allowing users to keep track of statistics over certain time periods. This feature does not erase the data recorded, but only resets the statistics count.
The instrument can be used as a standalone data logger or used with the RFC1000 wireless transceiver to transmit data back to a central PC. It transmits up to 500 feet (line of sight) to the RFC1000 transceiver. Multiple RFC1000s can be used as repeaters. A NIST certificate (standard calibration) is optional.
The RFCurrent2000A can be used as a single, wireless data logging system, or multiple models can be used in an expanded to a large-scale system. The instruments utilize MadgeTech 4 software. Data can be viewed in graphical or tabular formats, and users can view summary and statistics for further analysis.
