Understanding Sensor Accuracy: What Do ±0.5%, ±0.2%, and ±0.075% Mean?
When comparing industrial sensors, one of the first specifications engineers notice is accuracy. Manufacturers often advertise specifications such as: ±0.5%FS ±0.2%FS ±0.1%FS ±0.075%FS At first glance, these numbers may seem straightforward. However, many users misunderstand what these accuracy ratings actually mean and how they affect real-world measurements. In this guide, we'll explain how sensor accuracy is defined, how to calculate measurement errors, and when investing in a higher-accuracy instrument makes sense. What Is Sensor Accuracy? Sensor accuracy describes how close a measured value is to the actual value. No measurement instrument is perfectly accurate. Every sensor has some degree of...
