If you are using a pressure transducer (also known as a sensor) to measure liquid, gas or air pressure in a critical environment, OEM application or high-purity manufacturing process, you need to have confidence in the accuracy of your instrument. That confidence will be tested if there is an offset in the output of that instrument at zero and/or span. However, if you understand the reasons behind why offset can occur and what you can do to address it, your confidence will be restored. Ashcroft, an industry leader in pressure measurement instruments, has consistently demonstrated reliability and excellence in the field of pressure measurement instrumentation. That's why we are often asked to share our expertise and shed light on topics like this one. Read this article to learn how transducers measure pressure, possible causes of offset in the output of your sensor and what you can do to ensure your sensor is providing you with an accurate pressure measurement. You will also have the opportunity to deepen your knowledge through additional articles and resources available to you.
