Introducing our Power Factor and Energy Data Loggers.
A data logger is any device that can be used to store data. In the case of Electrocorders, these are stand alone portable devices that can read various types of electrical signals and store the data in internal memory for later download to a computer. The advantage of data loggers is that they can operate independently of a computer.
Electrocorders sample every channel 16 times per cycle, a cycle is 16ms at 60Hz and 20ms at 50Hz. At the end of each averaging period, 3 quantities are saved for each channel, the True RMS average, the Max, which is the highest cycle value during the period and the Min, lowest cycle value. In comparison to real time data acquisition systems, data loggers generally have lower sample rates; this is normally because they store data in internal memory which is has a limit. The higher the data rates the more memory required. Therefore when specifying a data logger it is important to determine the sample rate and the sample duration which can be used to calculate the required memory. The recording duration is dependent on the memory capacity of the data logger and the desired sample rate, Electrocorder recording duration ranges from 2 hours up to 300 days.
Electrocorders data loggers collect data independently of a computer and it is recorded in non-volatile memory for later download to a computer. The computer does not need to be present during the data collection process. This makes them ideally suited for applications requiring portability. As the data is stored in a non-volatile memory this means that data will not be lost if the power fails.
In many applications space is a an important consideration, the Electrocorder power data loggers range in size from 145 x 90 x 45mm to 260 x 180 x 190mm.
