Selecting the Correct DAQ and Amplifier Pairing for Precision Sensor Performance

June 25, 2020 by FUTEK

In this FUTEK white paper, learn more about the key specifications of a DAQ or PLC and how they affect the desired readout from the sensor.

Overview

Navigating specifications and terminology can be confusing. Typical questions that are asked pertain to what hardware a client needs to interface with their existing or newly purchased system.

When selecting a measurement solution, an analog full-bridge sensor is one piece of the puzzle. A complete solution also requires an analog-to-digital signal converter to enable data-logging and/or system automation. This is where a standalone DAQ or PLC with analog inputs comes into play.

To understand the performance of your future DAQ or PLC, it’s best to start with the resolution it provides. The resolution is based on the number of noise-free bits the ADC in your DAQ or PLC can read at your desired sampling rate. This is important because it represents the minimum voltage your DAQ or PLC can theoretically measure. We say theoretical because outside factors can affect your resolution, such as off-axis loading, mechanical vibrations, frequency response to applied loads, electrical noise, etc.
