A data logger is a device used to record and store the output of one or more sensors. In some cases, the data logger interprets the electrical signal from the sensor and converts it to units. In cases where a smart sensor provides digital output, the data logger simply records the data. Early data loggers were strip chart recorders that recorded measurement data onto paper.
Over time, data loggers evolved to store data digitally on various types of media. Today, data is typically stored on modern flash memory and often transmitted via a variety of telemetry methods.
Note: Similar terms for "data logger" include "datalogger," "logger," "data recorder," "data acquisition system," and "RTU" remote terminal unit. Which term is used often varies by industry or discipline. Today, a wide range of devices are referred to as "data loggers," and they can vary greatly in their functionality. For example, one data logger may be packaged together with a sensor for a single application-specific purpose, such as measuring temperature.
Another data logger may be a general-purpose device that is used in many different applications to log data from multiple sensors of varying types.
For the purpose of this discussion, our focus will be on general-purpose data loggers. Most modern, general-purpose data loggers are microprocessor-controlled electronic devices that can interface directly with a variety of sensors to do the following:. In addition to their measurement and monitoring functions, some data loggers can trigger an alarm or notification, as well as control an external device, in response to any of the following: a specific, measured site condition; time of day; or event.
For example, a data logger may be programmed to respond to a measured rise in water level by closing a floodgate and sending a notification to personnel. A data acquisition system consists of multiple electronic devices that act together to serve the primary purpose of collecting measured data.
The general-purpose data logger is often considered the brain of a data acquisition system, but it is only one of the interfaced components used in the process of acquiring, recording, transmitting, and analyzing measurements. These components may include the following:. The data logger can be programmed to scan the sensors of the data acquisition system repeatedly after a specified interval has passed the scan rateunder specified conditions, or after the occurrence of a particular event type such as rainfall.
A variety of methods can be used to accomplish this, including communication peripherals with onsite and telecommunication options. While many general-purpose data loggers are designed to be installed in protected environments, some are specifically developed for extreme environmental conditions. These extreme environments include mountainous terrain, deserts, jungles, mines, oceans, and glaciers.
A data logger is typically left unattended for lengthy periods to automatically process and record measurement data from a variety of sensors until the monitoring period ends, which may be decades later. The universal application of data loggers in climates across the world, from the poles to the equator, is often attributed to their ruggedness, compact size, wide operating temperature ranges, low power usage, and capability of operating in diverse environments.
The universality of sophisticated data loggers is further enhanced by their many connection types and programmable inputs, which enable them to measure almost any commercially available sensor.
Because data loggers provide a comprehensive, accurate, and reliable depiction of the monitored conditions without the need for site visits, they are an indispensable tool for unattended, long-term monitoring and control for numerous industries and applications.
In this illustration, several different types of general-purpose data loggers are displayed. These different types enable data loggers to accommodate a wide variety of measurement applications. While data loggers can be compared and contrasted on many different levels, the following are some primary characteristics that may be helpful for you to be mindful of:.
Smaller data loggers have a smaller footprint requirement, which enables a facility to use a smaller enclosure that is less expensive and less noticeable. A smaller data logger, however, is limited in functionality because fewer sensors or peripherals can be connected to it.
Although some manufacturers may not conform to this convention, the published operating temperature range typically refers to the range at which the data logger will operate within its specified measurement accuracy.
Measurements may still be recorded outside of this temperature range, but the accuracy of the measurement may be in question, and the data logger may not perform as expected. Other operational errors may also occur. Some data loggers only have a standard operating temperature range, whereas other data loggers may offer an extended temperature range option that is useful in environments with more extreme temperatures.
The wiring panel of a data logger provides terminals for connecting sensors.Description and definition of data loggers and data acquisition, and a summary of the main benefits. Data loggers are electronic devices which automatically monitor and record environmental parameters over time, allowing conditions to be measured, documented, analysed and validated.
The data logger contains a sensor to receive the information and a computer chip to store it. Then the information stored in the data logger is transferred to a computer for analysis. Loggers in the Tinytag range monitor parameters including temperature, humidity, single and three phase power usage, CO 2mV, mA, voltage, pulses or counts. Data acquisition is the sampling of the real world to generate data that can be manipulated by a computer.
Sometimes abbreviated DAQ, data acquisition typically involves acquisition of signals and waveforms and processing of the signals to obtain desired information. The components of data acquisition systems include appropriate sensors that convert any measurement parameter to an electrical signal, which is acquired by data acquisition hardware such as data loggers. Acquired data typically is displayed, analysed, and stored on a PC. Data logging can be done manually by constant human observation.
What’s the Difference between Data Loggers and Data Acquisition?
An example of this might be recording the temperature changes over the course of an hour in a centrally heated room using a timer, thermometer, pen and paper. However, using an electronic data logger is much more effective, accurate and reliable than taking periodic manual readings. It does the job of all the tools mentioned above, saving time and expense. The time taken to see the benefits of using data loggers will depend on the way in which the units are used.
However, quantifiable benefits from the using loggers may often be seen within a very short time. Typically, only one or two logging runs are required to pinpoint areas that would benefit from extra attention. Next page: Where and why are data loggers used?
