A data logger, otherwise known as a data recorder, is an electronic device or commuter program that constantly records data over time. It records in relation to the location and either utilises a built-in instrument or an external interface.
Data loggers primarily depend on digital processes and are usually comparable to a small portable box and utilise batteries, wires, and internal memory storage. It will have sensors and a programmable module.
Several data loggers can connect with a PC to show data via dedicated software. Simultaneously, some models relate directly to a device, such as an LCD mobile phone or other gadgets. It reveals data as a standalone device.
Data loggers are typically utilised in geotechnical monitoring on large scales because they can automatically collect real-time information from the sensors and display it over devices. You can leave data loggers alone and can still get optimum data anytime you require.
How many data loggers does your industry need?
The number of data loggers you need to purchase will depend upon the number of measurement points you have to monitor and the number of sensors you want to connect to. Data loggers are available in numerous configurations so that you can select according to your requirements.
The length of data loggers can record
The length of the data logging device can record will depend upon two instances—the power of the backup logger and its memory capacity. But a majority of data loggers have extreme longevity and durability, so they continue to operate for many years. In some cases, several of them will work for a shorter period only.
Batteries operate some data loggers, and they can program to record data from up to 5 to 168 seconds in linear mode. But the number of readings taken each day should be kept to a minimum to save on battery. These kinds of data loggers also give you optimum power supply options.
Some data loggers are programmed to override the data once the memory is at full capacity, while some of them will stop logging the data once the memory is full.
The alarm sets by data loggers
Monitoring specific structures such as tunnels, dams, and high-rise buildings predetermine a particular alert level by the logger as soon as something odd occurs, such as deformation or faults. The data logger sends an emergency signal either through an SMS or via an email.
However, there are several other loggers that come with a built-in lens, alarms, and even buzzers to alert the persons nearby in case of an emergency.
Retrieval of data
There are a couple of options available for the review and transmission through data loggers.
- Telemetry by GSM or GPRS model
In areas where GSM and GPRS service data is available, data from the automatic data logger can be relayed remotely via PC at a central location. The user must need to set up a data Sim card for every data logger.
- Readout data retrieval utilising laptop PC
The data logged from a data logger is directly downloaded via laptop or PC. Data can also be relayed to the central PC or server from a computer utilising either a USB pen drive or via the internet.
You must know what data logger devices can do for you as a business owner. In many cases, it is a crucial piece of equipment for businesses such as construction since it utilises sensors that can detect accidents and faults on site. Data loggers monitor environmental variables 24/7, which is critical in mitigating accidents.
