Definition - What does Data Logger mean?
A data logger is a portable instrument that automatically measures and collects environmental conditions, often in harsh conditions. It is used in a variety of industries as a standalone device and may use internal or external sensors. It is commonly used in drilling or tunneling operations in trenchless construction.
Alternatively spelled datalogger, the instrument may also be referred to as a data recorder.
Trenchlesspedia explains Data Logger
Any industry influenced by environmental factors could benefit from a data logger. The devices are used at remote weather stations, ocean buoys, and in the black boxes of airplanes. They are also used in such varied fields as wildlife research and motor racing. Data loggers are built to be tough and can be left unattended for long periods of time. They may also return data remotely via telemetry.
Using sensors to detect temperature, pressure, or other chemical or physical properties, a data logger generally converts analog information to digital data that can be processed by computers. Modern data loggers have memory and wireless capabilities and various power source options, including solar, battery, and AC power. Installed interfaces may connect to external sensors or data collection devices.
At trenchless construction sites, a data logger may be used to monitor hydraulic pressure, soil conditions or any number or other environmental factors. The data collected may affect operational decisions or allow monitoring of progress until completion of the project.
