The RFCurrent2000A is a wireless data logger with a digi-tal display, designed to measure and record DC current signals. This data logger can connect directly to low-level DC current sources which makes it ideal for battery usage studies, energy monitoring studies and other DC current monitoring applications. The RFCurrent2000A can also be interfaced with a wide range of current output sensors such as flow meters, pH transmitters and more. Through the software, the device can be programmed with engineering units, which convert the current readings into a different unit of measure such as flow rate. The engineering unit is available for display on the LCD screen as well as in the software. The RFCurrent2000A is available in 20mA, 160mA or a 3A measurement range.
The RFCurrent2000A features an LCD screen which provides instant access to the current reading, minimum, maximum and average statistics. The statistics can be reset through the keypad of the device, allowing customers to keep track of statistics over certain time periods. This feature does not erase the data recorded, but only resets the statistics count. The RFCurrent2000A can be used as a standalone data logger, or used with the RFC1000 wireless transceiver, to transmit data back to a central PC. The RFCurrent2000A transmits up to 500 ft line of sight to the RFC1000 transceiver. Multiple RFC1000’s can be used as repeaters and transmit up to 1000 ft line of sight to other RFC1000’s. This allows the data to be sent over a greater distance.
The RFCurrent2000A can be used as a single, wireless data logging system, or can be expanded to a large scale system, which can include hundreds of data loggers measuring different parameters such as temperature, humidity and more (additional MadgeTech wireless data loggers and transceivers may be required). The RFCurrent2000A utilizes the latest MadgeTech 4 Software. Data can be viewed in graphical or tabular formats and summary and statistics views are available for further analysis. The software features export to Excel®, data annotation, digital calibration and more.
