Another application for event loggers is for Production Monitoring. It is an effective tool in the hands of management. Management can observe when a particular machine was switched on, when it was idle, when there was no power. Information about run time, idle time etc can be derived from the logs in the event logger.
In the simplest form the event logger can generate a report of at what time a particular system was switched on and at what time it was switched off. Typical report can be.
Number of such units can be networked on an RS485 bus and connected to PC. Ajinkya provides Production monitoring software which can upload data from these units and generate shift wise reports.
Data Loggers are electronic instruments which capture and record data related to physical parameters like temperature, humidity, pressure, liquid flow etc. as well as electrical parameters like voltage, current etc. and reproduce them in a form suitable to the user. The reading of information, storage and reproducibility are the important parameters that define a data logger.
Depending on how each of these parameters are handled data loggers can be classified in various categories and have various nomenclatures.
Here are the various parameters that user can select from to choose a data logger
