What is a data logger?
Data registrar or register or sensor Or stores the external device over time. Most data loggers are usually small and portable and have laboratory, test and measurement applications. Data loggers have a sensor that measures the data of the desired parameter and then stores it in its internal memory. Some recorders have a display and the stored data can be viewed in it. Data loggers are usually connected to the computer via a USB interface, and the measured data can be viewed and processed on a computer by a special data logger software. Data loggers are usually connected via USB link It is connected to the computer and the measured data can be viewed and processed on the computer by a special data logger software.
One of the important advantages of using data loggers is the ability to collect information 24 hours a day. Data loggers are usually left unattended as soon as activated during the monitoring period measurement And save the information. This feature allows a comprehensive and accurate image of the environment under monitoring conditions such as air temperature or humidity.
Application of the data logger includes the following :
Data storage of measurement of meteorological parameters such as wind speed / and wind direction, temperature, relative humidity, solar radiation in the meteorological station without care. Hydrographic care
Auto saves oil moisture
Automatic gas pressure saving
Road traffic counting
Measurement of temperature (humidity and…) of perishable materials during shipment
Process monitoring for maintenance and troubleshooting of applications
Vibration measurement and transport conditions (fall height) in distribution
Tank level monitoring
monitoring Relay status in railway signaling
Storage of ‘electrical load diagrams’ to manage energy consumption.
Data collection of temperature and pressure variables along the pipeline
Monitoring of oil and gas pipelines
Characteristics of a data logger:
Number of channels: The number of data logger channels indicates the number of sensors and converters that can be connected to the data logger at the same time.
1. Sampling frequency sample: The number of times the data logger reads the data of each sensor and transmits it to the computer or memory is called the data logger sampling frequency. As a data logger with a sampling frequency of 300 Hz, it means that every one hundredth of a second, the data obtained from the sensors is transmitted to a computer.
2. Support type sensors: Usually each data logger supports specific sensors and converters. For example, a data logger may only be able to support thermal sensors.RTD But can not support thermocouples.
3- Processing the collected data: Usually, each data logger is equipped with a software that makes it possible to apply its settings and view the graphs obtained from the sensors during sampling.
4- Data recording time: A basic parameter in data logger systems is the ability to record information for a long time, for example several years. To achieve this goal, data logger systems need to have high-volume storage media and very low power consumption.
Data logger components :
Hardware: Hardware converts the desired signals into digital data, which includes: sensor, Signal recovery circuits (such as amplifiers and noise reducers) and analog-to-digital converter circuits.
Long-term data storage hardware, usually a memory card or computer.
Datalogger software used to collect, analyze and display data
Data logger cable that connects the data logger to the computer to transfer data stored on the computer
