Data Loggers

Data loggers, also commonly called data acquisition systems, are composed of several components that receive electric signals from various devices. These systems then convert those signals into a digital form that can be analyzed by humans or computers. The received data is stored on computers and evaluated with the help of software programs that are designed to understand and process the information.

Data logging begins with the instruments and devices that transmit the signals to be translated. These instruments may serve various purposes, from measuring the temperature of a laboratory environment to measuring the speed of flow in a pipe. Data loggers can be fitted with built-in instruments or simply built to collect data from external sensors. A transducer converts the measurements into an electric signal that can be understood by a computer. A data logger is responsible for storing and recording the data collected from various sensors.

These are often used to track data over a period of time or to collect data in relation to a particular location. Data loggers offer the advantage of being able to continually collect data without monitoring. Once they are set up and activated, they can be left unattended for the duration of the collection period.

Data acquisition is used in various industries to accomplish a wide range of tasks. To forecast the weather, for example, meteorologists rely on data loggers that measure temperature, humidity, and pressure. Manufacturers also use data loggers to monitor their equipment and to make any necessary adjustments. Data loggers can also be used to control test conditions, activate safety alarms, and regulate temperature in sensitive environments.
