Data loggers Manufacturers online

Data loggers are electronic devices that automatically record data over a certain period of time.

They are used in a variety of applications to monitor environmental or operating conditions.

Below you will find how data loggers work, an overview of types, their areas of application, their benefits and important aspects of their use:

How they work:

• Data loggers measure physical variables such as temperature, humidity, pressure, light intensity or even electrical signals using suitable sensors.
• They collect this data at regular intervals and usually store it internally on a memory card.
• Once the data has been recorded, it is transferred to the computer either by cable, WLAN or by physically transferring the memory card.
• Data loggers allow the recorded data to be analyzed at any time.
• The data logger is usually configured using software in which the measurement interval, the type of measurement and the storage location are defined.
• Software can usually also be used to analyse and visualize the data (e.g. in the form of diagrams).

Applications of data loggers:

1. Environmental monitoring:
Measurement of temperature, humidity, CO₂ content, etc.

2. Goods logistics:
monitoring the storage conditions of sensitive goods (e.g. food or medicines).

3. Research:
Collecting data on long-term studies.

4. Industry:
Machine monitoring for early detection of problems.

5. Building management:
monitoring of heating, ventilation and air conditioning systems.

Advantages of data loggers:

• Long-term recording: independent and continuous data acquisition without human intervention.
• High accuracy: Precise measurements through specialized sensors.
• Versatility: Can be used in different environments and for different parameters.

Important aspects when using data loggers:

• Calibration: regular calibration of sensors for accurate measurements.
• Memory capacity: Depending on the application, the memory should be large enough to hold the amount of data for the desired time period.
• Measurement interval: The shorter the interval, the more data is recorded, but also the more memory is required.

Data loggers are indispensable tools in many areas, as they collect data reliably, accurately and cost-effectively over long periods of time.

Here are the most important aspects to look out for when buying data loggers:

When purchasing a data logger, several factors should be considered to ensure that the device meets the requirements of the application in question:

• Choose a logger that can accurately record the measured variables you want to record (e.g. temperature, humidity, pressure, CO₂).
• This is an important factor, especially for sensitive measurements such as in medicine or research.
• Note the smallest change that the logger can measure and display. The finer the resolution, the more precise the measurements.
• The logger should offer adjustable measurement intervals to adapt the recording frequency to requirements (e.g. seconds, minutes, hours).
• The memory should be large enough to record data over the planned measurement period without data loss.
• Check whether the logger has internal memory or removable memory cards.
• Data loggers should have a long battery life, especially if they are to be used for long periods without a power supply.
• Some loggers have replaceable batteries, others have built-in rechargeable batteries.
• Make sure that the logger offers the right data transfer method for you (USB, Bluetooth, WLAN, radio).
• Check that the transmission works smoothly with the existing software and hardware.
• Intuitive and powerful software for data analysis and visualization is crucial. Ensure compatibility with your operating system.
• The data logger should be easy to configure and operate.
• Depending on the area of application (e.g. extreme temperatures, humidity, shocks), the logger should be suitably robust.
• For use in harsh environments, loggers should be protected against dust, water or shocks (IP65, IP67).
• Make sure that the logger can be calibrated to ensure precise measurement results in the long term.
• Consider the price compared to the functions, measurement accuracy and service life of the logger.
• Think about follow-up costs such as calibration or replacement batteries.

By considering these points, you ensure that the data logger meets the requirements of your specific application and provides reliable measurements.
