data loggers

In appearance and by mentioning the basic specifications, these two tools, namely the recorder and the logger, look the same, but by examining different models, their differences become apparent. Loggers for recording information such as temperature, pressure, humidity, etc. are usually small and portable and are powered by a battery that is equipped with a microprocessor and has limited internal memory for data storage and a number of sensors. For example, temperature and humidity loggers or pressure loggers for limited recording of values ​​with a not very short time interval. Loggers are usually without screen and their information and settings are possible by connecting to a computer, which is usually the USB port. Data loggers are used to record information in a period of 24 hours or a little more depending on the sample rate or sampling rate and battery life and ... While decoders or information recording systems or DAQ for integrated systems such as SCADA or DCS and recording information of multiple channels with various inputs such as thermocouples, current and voltage signals as well as sensors such as load cell and strain gauge, Tachometer and ....... which is mainly in accordance with the needs of large industrial plants and multiple outputs of industrial sensors such as pressure, temperature, flow sensors ..... Industrial records are referred to as relatively larger equipment compared to loggers and with the ability to display and record values ​​on the monitor screen and internal and external memory and in older models on paper that can communicate with various industrial and non-industrial networks with protocols such as They have TCP / IP and LAN to Madbas and Fieldbus. Below, with a little care, the images of the loggers are simply distinguishable by records.
