This article was originally published on June 9, 2021, and was updated on March 4, 2024. Pressure gauges play a critical role in your process applications. They accurately and reliably measure and monitor pressure to determine if process systems are working effectively and efficiently, or if you need to make system alterations or adjustments. This helps ensure the safety of your personnel, the efficiency of your processes and the quality of your products. But what happens when your pressure gauges stop working? Your entire operation is at risk. That's why periodic instrument audits are good practice. Ashcroft has been conducting comprehensive instrument audits for 10 years. As the product lead for process gauges, I see the results of these audits and can tell you why instruments fail in the first place. The good news is that most of these “instrument killers” we've identified can be prevented if you know the warning signs. In this article, you will learn the primary indicators that tell you your pressure gauge may be failing and the 6 most common pressure gauge problems and solutions that we found in our instrument audits. When you are done reading, you will know what to look for and be prepared to address any of these issues ahead of time. Armed with this information, you will be able to keep your processes running safely, smoothly and effectively.

Pressure Instruments | diaphragm seals

If you are new to the world of diaphragm seals or just want a refresher on how they work, you've come to the right place. A diaphragm seal (also known as an instrument isolator) is a protective mechanism that connects to the process side of a pressure measurement instrument. The primary function of a diaphragm seal is to prevent the sensing element of your pressure instrument from getting damaged by any corrosive process media or clogging in your application. Without using a diaphragm seal in place to protect your instrument, you will not be able to accurately and effectively measure the pressure in your system, putting your entire operation at risk. Why trust Ashcroft? We are an industry leader in pressure and temperature measurement instrumentation and are often asked for insight regarding the benefits of these instruments and how they work. In this article, I will review how diaphragm seals are used in different applications and provide links to additional resources in case you want to expand your knowledge on the subject further.

pressure gauge | semiconductor industry | high purity

When you think of semiconductors, you may picture all the ways they make our lives easier. After all, we rely on semiconductor applications every day for conveniences like cell phones, computers, cars and other electronic devices. But for those of you who work in semiconductor manufacturing, you also know the demanding and challenging nature of making them. The hazardous nature of the manufacturing process requires stringent protocols, approvals and specialized equipment that can perform with precision and accuracy under harsh conditions. So, when it comes to monitoring the distribution of ultra-high purity (UHP) gases flowing through the process, choosing the right pressure gauge is critical. As a product lead at Ashcroft – a recognized authority in pressure and temperature instrumentation - I have been working with Ultra High Purity (UHP) Pressure Gauges for several years. In my role, I am often asked how to choose the right UHP gauge for these kinds of applications. Of course, my answer is, it depends. In this article, I will review how and where semiconductors are made, the role UHP gases play in the manufacturing process and the specific features you will need when choosing a pressure gauge for UHP applications. When you are finished reading, you will also see additional resources that you can use as a reference on the topic of high purity.

pressure gauge | Pressure Instruments | pressure sensors

If you are working in an industry that requires instrumentation to measure and monitor pressure in a system, you already know the basic principle of pressure measurement. According to Pascal's Law, pressure is proportional to the force and inversely related to the area over which the force is applied. In other words, pressure is equal to force per unit area. Figure 1: Pressure Equation. Different systems and applications require different types of pressure measurement instruments. For example, mechanical pressure gauges may be used as visual indicators of pressure levels throughout a process. Conversely, pressure transducers or transmitters can sense changes in a system’s pressure and send a signal to a control room. If you are new to your industry and want to learn more about pressure instruments, this article will give you a high-level overview of how to read pressure, definitions of pressure types and the instruments used to measure pressure. Ashcroft is a recognized global leader in pressure instrumentation and is a trusted authority for related information. When you are done reading, you will find additional resources related to pressure measurement that may interest you.

Bimetal Thermometers | RTD | thermocouple | thermometer | gas-actuated thermometer

All industrial applications use some kind of temperature instrument to ensure process temperatures stay within an acceptable range. Choosing the right device can help protect your equipment and your operators from extreme temperature shifts. However, the type of instrument you use will depend on many factors, including the temperature limits of the operation and the instrument, the required output and more. As a global leader in temperature and pressure instrumentation, Ashcroft created this article as a high-level overview of industrial temperature measurement options. If you are an industry novice or just want a refresher on the basics, this can serve as a good reference piece. Read on to learn about the different types of industrial temperature instruments, how they work, where they are used and why you might choose one over another. When you are done reading, you will find additional resources related to temperature measurement that may interest you.

pressure transducers | semiconductor | semiconductor industry

Pressure sensors, including pressure transducers and pressure transmitters, are a critical aspect of semiconductor manufacturing. These instruments measure pressure to control the flow and distribution of ultrahigh purity (UHP) gases and liquids safely and effectively throughout the production process. In my last article about transducers for semiconductor UHP gas applications, I explained how Ashcroft and our parent company Nagano Keiki Co. LTD, have been providing pressure and temperature instrumentation to semiconductor manufacturing customers globally for decades. This piece will provide more insight into the liquid process of semiconductor manufacturing and review the pressure monitoring features to look for in instruments that are designed to perform well in these complex processes. When you are done reading, I hope you will have a better understanding of the use of UHP fluids in semiconductor applications and the solutions employed to accurately measure pressure. You will also find related articles and guides that you can use as references for this evolving topic.
