16 to 112 Channel Data Logger used for Industrial Applications: An Approach

With the advancement of technology, the processes are becoming more and more complex. Due to this increase in complexity, for efficient analysis of process the number of parameters required for data acquisition also increases. Data Acquisition is simply the gathering of information about a system or process. It is the process of collecting data in an automated fashion from analog and digital measurement sources such as sensors and devices. Before the computer age, most data was recorded manually or on strip chart recorders. Many new generation data acquisition products have been developed due to emergence of microcontroller that enables real time gathering, analysis, logging and controlling of data. To meet these requirements the demand of an improved, efficient and up to date data logger is increasing. A data logger is an electronic instrument that can record digital or analog measurements over a period of time. It consists of a sensor, microcontroller, a data storage device and communication for controlling system. Data loggers have an on board memory that is large enough to hold data. That is recorded over a longer period of time. Data loggers are provided with real time clocks to record the date and time of acquisition.
