Do you really know your pressure sensor accuracy ?
Accuracy has a price. The cost of a pressure sensor is a function of its accuracy, the more accurate the sensor the more expensive it will be. From a manufacturing point of view, the wrong sensors can cause expensive quality or efficiency problems. That is why it is important to understand how manufactures calculate accuracy and recognize what parameters to look at when comparing pressure sensors. By understanding how manufactures calculate accuracy, you will be able to make a more informed decision when evaluating pressure sensors. Ensuring the next sensor you select will have the required accuracy at right price for application.
What is accuracy? The International Electrotechnical Commission’s (IEC) definition of accuracy is the maximum positive and negative deviation from the specified characteristic curve observed in testing a device under specified conditions and by a specified procedure. Unfortunately when it comes to defining accuracy for a pressure sensor it’s more complicated. Accuracy has a large effect on the cost of a pressure sensor or even more important, the quality or efficiency of the process it is measuring. It is important to understand what factors determine accuracy and what questions to ask when selecting a sensor.
