Data acquisition vs data logging

  • Data Logger electrical

    The term data logger is primarily used to describe a device that stores data for subsequent download to a host PC.
    Data recorder is a broader term used to describe any device that records sensor or signal inputs.
    Either device may also include real-time features such as monitors and alarms..

  • Data Logger Price

    The term "data acquisition" refers to software and hardware that we use to measure the physical characteristics of real world processes.
    With the term "control", we refer to the process of making changes to specific attributes in the real world..

  • Data Logger Price

    There are four methods of acquiring data: collecting new data; converting/transforming legacy data; sharing/exchanging data; and purchasing data.
    This includes automated collection (e.g., of sensor-derived data), the manual recording of empirical observations, and obtaining existing data from other sources..

  • How does data logging work?

    A data logger is an instrument that monitors and records changes in conditions over time.
    They can be single, stand-alone units or consist of multiple channels.
    Most stand-alone units are battery-powered, allowing them to record while in transit and for extended periods of time..

  • What is the difference between DAS and DAQ?

    Data acquisition systems (DAS), also called DAQ systems, help validate designs and identify product defects early in the development process.
    With thousands, if not millions, of products in development every day, you can imagine how many different measurement systems there are..

  • What is the difference between data logger and data acquisition system?

    In most cases, both device types now feature Ethernet or Wi-Fi interfaces in today's products.
    A data logger will typically store data in non-volatile flash-based memory.
    A DAQ system will utilize a connected PC, network storage device or direct hard disk drive.Jan 14, 2020.

  • What is the difference between data logger and data acquisition?

    While DAQ systems are more like a race car, made to go very fast for a relatively short period of time, data loggers are intended to record slower but for longer durations.
    The application is what should drive your choice of instrument.Apr 2, 2020.

  • What is the difference between data logger and data recorder?

    The term data logger is primarily used to describe a device that stores data for subsequent download to a host PC.
    Data recorder is a broader term used to describe any device that records sensor or signal inputs.
    Either device may also include real-time features such as monitors and alarms..

Apr 2, 2020So while a data logger is literally a “DAQ device” (aka “data acquisition device”), it cannot be properly classified as a DAQ system. Learn more  What is a DAQ system?What is a data logger?Data storage comparison
Generally speaking, the instrumentation market understands a data logger to be a relatively slow sample rate device; typically, once per second and slower while a data acquisition system (or DAQ system) has sample rates that reach into the MHz or even GHz range.

Should you pull data from a data logger?

You must therefore pull information from a data logger, rather than having it pushed to you by a data acquisition system.
And so, using a data logger, by the time you learn a problem has occurred, it’s too late to do anything.
The key difference is already spelled out:

  1. proactive over-reactive
  2. push instead of pull

Time Blurs Traditional Distinctions

If we fast forward, the above legacy definitions for data logger and data acquisition have all but vanished.
Whether due to advancements in technology, evolution of the vernacular, or a combination of both, the two terms are increasingly and likely permanently used interchangeably.
We talk to customers who say they want PC-connected data loggers, a.

,

What is the difference between a data logger and a DAQ?

Since the two are quite similar in many ways, it is understandable for manufacturers to develop some data loggers or DAQs which are overlapping when it comes to features and function.
Basically, a data logger is a data acquisition system but a data acquisition is not a data logger.
Most probably in the future, these two will become one.

,

What is the difference between a data logger and a logger?

Data loggers were battery powered.
Data loggers were higher resolution devices.
Data loggers recorded to their own memory.
Data loggers operated at very slow sample rates.
These distinctions have blurred over the last twenty years or so due mainly to technology advancements.

,

What is the difference between data loggers and data acquisition systems?

Data loggers used their own memory in recording.
Data loggers typically operated at slower sample rates.
Data loggers are stand-alone devices whereas data acquisition systems must remain tethered to a computer in order to collect data.
However, most of these differences have actually been fading away in the last twenty years or so.
