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. The good news is, Ashcroft has been a pressure solution expert for decades. Additionally, as a product leader, I personally have extensive experience in precision pressure and temperature measurement that stems from my degree in electrical engineering and working in the industry for more than 40 years. In this article, you’ll learn: ● What these pressure sensors do and how they work ● Why output (the type of signal you need) will be the primary reason to choose one option over the other ● How each sensor performs in terms of accuracy, cost and reliability When you are done reading you will be able to speak knowledgeably about pressure sensor basics and know whether a pressure transmitter or transducer is the best fit for your needs. So, let’s get started!

Your pressure switch can be impacted by many factors when used in an application. Pressure and temperature ranges can interfere with your measurements if you are using the wrong pressure instrument for the job. An appropriate microswitch for your pressure switch can mean the difference between a reliable, repeatable reading or not. How can you ensure you are choosing the right microswitch for your application?

Pressure gauges come in a number of different options, including range, materials and size. You can even customize the gauge dial. Different dial sizes can suit your particular application and the location of your pressure gauge. So, what size pressure gauge is best for your application?

When your application involves hazardous locations, it’s important to use instruments that are up to the challenges these applications can offer. In environments with a fire or explosion risk, the wrong pressure instruments can lead to operator injury, equipment damage or worse. How can you avoid these problems?

Not every application is the same, so you need to get the right equipment for your specific needs. When it comes to temperature measurement, inaccurate readings can severely impact your process. So, how can you ensure you are correctly and reliably monitoring temperature?

Thermowells are essential to protecting your thermometer or temperature sensor in your high-pressure or high-temperature applications. They can protect your investment and keep your measurements accurate, no matter how extreme the environment. One of the top questions we receive here at Ashcroft from those in the temperature measurement industry is how to properly fit a thermowell. What measurements are needed? What is a u-dimension and how does it factor in? Many factors are at play, and it can be easy to get the wrong size if you aren’t paying attention.
