A pressure transducer, which can also be referred to as a pressure transmitter or pressure sensor, is an electronic device that measures and monitors the air, gas or liquid pressure flowing through industrial systems. Although they appear small, these instruments are built with advanced technology to provide accurate and reliable pressure measurements at different stages of the process. Ashcroft is an industry leader in pressure measurement instrumentation and created this article to provide a basic foundation of information about transducers for the industry novice. Read on to learn how they work and where they are used. You will also get a high-level overview of the different types of sensors, manufacturing standards, sensor accuracy and more. When you are done reading, you will also find additional resources about transducers that may interest you.

For the industry novice looking to understand the basics of pressure measurement instruments, it can be confusing and overwhelming to search through the seemingly limitless number of available transmitters and transducers.

Your cell phone, computer, television, car and any other electronic device you use each day all depend on semiconductor applications to exist. But these demanding applications require specialized high-purity equipment and instruments to run safely, efficiently and properly. Pressure transducers (and pressure transmitters but for simplification in this article I will refer to them as "pressure transducers") are crucial to the semiconductor process, but only if they are manufactured a certain way to handle hazardous environments. How do you know what makes the best semiconductor pressure transducer?

You can find hydrogen in a wide range of industrial applications and processes just about everywhere these days. Hydrogen is one of the fastest-growing alternative energy resources used today. Some of its uses include:
