Introduction

When moving physical magnitudes in the analog world to the digital world, our most important limit is "resolution." How small pieces an analog signal is divided into affects the accuracy of your measurement. 12-bit or 16-bit systems, which were standard in the past, have difficulty meeting today's precise engineering needs. So why should you use a 24-bit Analog to Digital Module? Let's solve this "precision chemistry" together.

Resolution: Why Does the Number of Steps Matter?

Resolution refers to how many steps a measurement range is divided into:

  • 16-bit: 65,536 steps.
  • 24-bit: 16,777,216 steps!

This massive difference means that while measuring a weight of 10 kg; while you can see changes of approximately 0.15 grams in a 16-bit system, you can see changes at the microgram (mg) level in a 24-bit system.

Why Should You Choose 24-bit?

  1. Dynamic Range: You can read even very small signals (micro-volt level) without losing them in the noise. Numerically more steps capture even the slightest oscillations of the data.
  2. Digital Gain: While hardware amplification of the signal causes noise, 24-bit resolution reads the data in such detail that even when you "zoom" via software, the data is not corrupted.
  3. Preparation for the Future: Industry 4.0 and AI applications always need more and more detailed data for analysis.

Product Placement: Ultra-Precise Data Acquisition with ZMA Series

At Amazeng, we have standardized 24-bit technology in all data acquisition devices we develop.

  • ZMA Data Acquisition: Not only offers 24-bit resolution, but can also perform 1000 samplings per second. This means "both very precise and very fast" measurement.
  • Low-Noise Design: It is not enough for an ADC module to be only 24-bit; the electrical design on the board must also be made in such a way as not to compromise this precision (low-noise). ZMA series reflects all the power of 24-bit to the field with special isolation and signal cleaning layers.

Conclusion

The rule "you cannot control what you cannot measure" applies in engineering. Using a 24-bit Analog to Digital Module is like removing the blindfold from your system's eyes and giving it microscopic vision capability.
