A data logger is a device that records equipment parameters and events (such as failures and shutdowns) for further monitoring and analysis. The data logger methodically records the occurrences, observations, or measurements.
Moreover, a data logger is a device used for data logging. When it’s necessary to take continuous readings of an instrument, data loggers come into play. Data loggers are an essential tool that are widely utilised in the geotechnical instrumentation and monitoring industry.
A data logger, also known as a data recorder, is an electrical gadget or computer software that continually logs information about a specific area over time using either an internal instrument or an externally connected one.
The data loggers often resemble a compact portable box or case with batteries, wires, internal memory storage, sensors, and a programmable module. They are based mostly on digital processors.
How long can Data Loggers Record?
The power backup of the data logger and its memory capacity are two factors that affect how long the data logging process lasts. Even if the majority of data loggers have great endurance and durability, they keep working for many years. While some of them just work for a brief length of time.
The data recorders for the Encardio are battery-powered and provide a linear data recording time range of 5 to 168 seconds. To preserve the battery, the number of readings obtained each day should be reduced to a minimum. You have access to a variety of power supply options with this data recorder.
The amount of time the logger can run until the memory is full is calculated by multiplying the sample rate by the number of channels being recorded. When the memory is full, some data loggers are configured to stop recording data, while others are programmed to overwrite the data.

What does a Data Logger do?
The following are the uses for data loggers:
- Thorough tunnel monitoring is necessary for the tunnel’s long-term safety in order to analyse its behaviour over time, particularly with regard to the rheological characteristics of the rock mass and any obvious changes to the fault zones, walled sections, inflow, etc.
- The inside lining of the tunnels is installed with a number of equipment, including tilt metres, strain gauges, extensometers, etc., to monitor any deformities. A data logger continuously records and stores the information from these sensors in its internal memory.
- Monitoring the structural health of existing structures to maintain tabs on their performance over time and the impact of nearby excavation or construction In the event of an emergency, data loggers generate a prompt warning so the user can take precautionary action.
- Monitoring of landslides to prevent accidents and generate early warnings to prevent loss of life and property.
