In industries such as manufacturing, food processing, chemical production, HVAC and more, maintaining precise temperature measurement is important to ensure product quality and safety. Bimetal thermometers address challenging environments by providing accurate and reliable temperature readings that are necessary to protect your product, your process and your operators. But how do you determine the best bimetal thermometer for your specific application? As the product manager for temperature products at Ashcroft, a leader in pressure and temperature instrumentation, I can guide you through the selection process. Read this article to learn more about the functions and applications of bimetal thermometers and the key considerations to help you choose a high-quality option tailored to your requirements. I will also share some additional resources that can answer other questions you may have about these instruments.

Critical environments like cleanrooms, data centers, laboratories, hospital operating rooms, isolation rooms and other controlled spaces must adhere to strict environmental guidelines requiring close pressure monitoring. To ensure these areas are not compromised, your pressure-measuring instruments must be highly accurate, reliable and compliant with these very specific requirements. Choosing the wrong instrument can result in equipment damage, worker injury or incorrect measurements. As the product manager who oversees the low-pressure sensor product line at Ashcroft, I understand the complexities of these environments and am often asked for guidance on selecting sensors for critical applications such as these. In this article, you will learn some factors to consider when choosing a low-pressure transducer for critical environments, so you’ll know you’re getting the proper equipment for your process. You will also be directed to additional resources that can help answer other common questions about this topic.

However, when it comes to selecting the appropriate pressure switch for a specific application, the challenge is understanding all the options available and finding the right one for your specific needs. During my time working in the pressure measurement industry, and specifically with Ashcroft, a leader in pressure instrumentation, I am often asked when an electronic pressure switch (also referred to as a digital pressure switch) is the better option than a mechanical switch. Of course, the answer depends on the application. In this article, you will learn how an electronic pressure switch works and some scenarios when electronic has advantages over mechanical options.

If you work in a refinery, petrochemical plant, or power generation facility, you likely face the challenge of managing high temperatures and pressures associated with steam applications. Under these harsh conditions, pressure gauges and other instruments can become damaged, which can lead to operational failures. A steam siphon is one solution that can provide a simple yet effective way to protect your instruments from these elevated process temperatures. As a product leader in process gauges at Ashcroft, one of the most common questions I’ve heard (and one that our customer service team often receives) is, “What is a steam siphon and how can it protect my pressure gauge?” In this article, you will get the answer as well as details on the two most common types of steam siphons and how they work. You will also get my guidance on selecting the right siphon for your application. From this point on, when I mention the term siphon, I am specifically referring to a steam siphon, as other siphons can also dissipate heat for high process temperatures not related to steam.

Diaphragm seals and isolation rings are both integral to the safe and efficient operation of your application. Whether it is a chemical plant, water treatment plant or mining facility, these isolators are used throughout the plant to protect instrumentation from harsh process media. But what’s the difference between these two instruments? And, when would you use a diaphragm seal instead of an isolation ring? Throughout my career, I’ve heard this question a lot. Not just from the customers in my territory, but also from product distributors during any of the product training seminars that I conduct for Ashcroft. Continue reading to learn the basic differences between diaphragm seals and isolation rings, which you would use one over the other in specific applications and why. You will also see links to additional resources to learn more.

Regardless of the industry, if your system requires a pressure gauge to measure and monitor process pressure, you want to ensure it offers the accuracy, safety and quality features you need. That includes protection from excessive pulsation and/or vibration found in challenging conditions. While there are many types of pressure gauges to choose from, the challenge is finding the one that works best for your specific situation. Liquid-filled pressure gauges, direct drive pressure gauges and dampened movement options like Ashcroft’s PLUS!™ Performance all have pros and cons to consider. As a leading authority in pressure gauges, Ashcroft helps customers like you understand the advantages and drawbacks of different products so you can make a more informed purchasing decision. Read this article to learn about the types of pressure gauges available for applications with high vibration, pulsation and other demanding conditions. When you are done you will be able to decide which one is best for your application. You will also find additional resources that can answer other common pressure gauge questions.
