What Does Field Data Logger Mean?
A data logger is a portable, electronic device that is used to record and measure various environmental data. They are usually battery powered and come equipped with internal processors, data storage capacity and multiple sensors. Data loggers can be calibrated to automatically record data at specific intervals over a period of time to be transferred to a computer for further analysis.
Trenchlesspedia Explains Field Data Logger
Field data loggers can be used to record a variety of environmental data including:
- Relative humidity
- Water level
- Soil moisture
- Dissolved oxygen level
- Wind speed etc.
Although data logging can be done manually, electronic data loggers provide much more accurate and reliable readings than human observations. Furthermore, data loggers can record data for long periods of time (days or months) unattended. Data loggers are commonly used in trenchless construction to record information that can affect tunnel construction such as such as road traffic, soil moisture, soil properties and groundwater level.
