YDH series data logger is the new generation of data loggers. It combines the latest communication technology with advanced measurement technology, and is based on FPGA technology to make it especially powerful. It can process multi-analog input channels at both low and high rates of sampling. Measurement data can be accurately acquired, independently stored and transmitted to the internet or a PC for evaluation via optional USB, LAN, WLAN or GPRS. YDH series data logger is available in optional versions which differ only in the number of analog and digital inputs they can process. All YDH series data logger could be expanded to 4GB memories that can independently store up to 125 million measurement values with date and time stamps to msec precision. Storage capacity can be extended as required via external USB or LAN storage devices (NAS). An integrated, energy-saving sleep function automatically switches off the device during breaks in measurement acquisition. The All YDH series datalogger operates with solar units. Precision measurement is ensured through the use of a 16-bit converter. Voltages can also be precision recorded to the V range. All channels are galvanically isolated to suppress earthing loops and the tried and tested input circuitry protects the device against voltage spikes. Electromechanical components are avoided (relays multiplexer), and the device operates noise and maintenance free. The patented analog inputs guarantee years of reliable measuring work.
