Data Logger


Data logging is the technique used to measure and record the physical parameters over a period of time. This method is used in various applications like environmental monitoring, health monitoring, machinery monitoring, vehicle data logging etc. Common measurements in Data logging include measurement of temperature, pressure, voltage, strain, force, acceleration, current etc. Data logger is a paperless chart recorder that measures the physical parameters and converts them in to digital data. Data logger has built in display or facility to transfer the data into the PC. The data can be stored for long time and it is easy to generate the report at any time. Data loggers are more easy to use than the Real Time Data Acquisition Systems and Chart Recorders.
