Monitoring low-pressure processes comes with unique challenges. In industries ranging from food and beverage to wastewater treatment to liquefied natural gas (LNG) transfer, even modest changes in pressure can affect efficiency, product quality, or safety. Directly exposing instruments to these processes often leads to media buildup, corrosion, or inaccurate readings. That’s where using assemblies that combine pressure gauges, transducers, or switches with diaphragm seals or isolation rings can help. Ashcroft, a leading authority in pressure and temperature instrumentation, has decades of experience helping industries overcome these challenges. As the product lead for diaphragm seals and accessories, I help customers find the best assembly for their specific needs. Read on to learn: How different industries and instruments define “low pressure” Which assemblies work best with gauges, mechanical switches and sensor-based instruments How assemblies support applications across sanitary, industrial, utility and cryogenic environments — with LNG as a primary example When you are finished, you will know how to ensure accurate measurement and keep your operations running efficiently with the right seal or isolation ring assembly.

Selecting the right process connection for your pressure gauge, switch, or transmitter may seem like a small decision—but it can make the difference between a reliable installation and one that leaks, fails, or requires costly rework. With so many connection options available, it’s easy to feel uncertain about which one is the best fit for your application. That’s where Ashcroft can help. With over a century of experience in pressure instrument manufacturing, we’ve guided countless customers through their connection challenges. Read this article to learn why process connections matter, the different types available, what they’re best suited for and how to select the right one for your system.

Pressure gauges are among the most widely used instruments in industrial, commercial and sanitary applications. From monitoring boiler pressure to validating sterile conditions in pharmaceutical processes, gauges provide operators with the real-time data they need to keep systems safe, efficient and compliant. But what happens when a gauge stops working? While it may seem practical to repair the instrument instead of replacing it, this is not always the best option. Ashcroft, a leading authority on pressure gauges since 1852, has been addressing this question with customers for more than a century. Read this article to understand why replacing a damaged gauge can be a better option than trying to repair it on your own.

In sanitary industries such as food/beverage and pharmaceutical/biotechnology, reliable pressure measurement is necessary to ensure product integrity and public safety. Pressure gauges used in these environments must be able to withstand rigorous cleaning cycles, resist contamination from bacteria build-up and comply with strict sanitary standards. Ashcroft, a leader in pressure and temperature instrumentation, offers two sanitary gauges designed for these challenges: the 1032 Sanitary Pressure Gauge with Tri-Clamp® connections and the 1033 Sanitary Pressure Gauge with DIN 11851 hygienic unions. Both models combine hygienic design with rugged performance, ensuring accurate readings in critical processes. Read this product review to explore the unique features, specifications and typical applications of each pressure gauge. At the end, you will also see a side-by-side comparison to help you determine which option is best for your sanitary process.

In industries such as pharmaceutical, food, dairy and biotech, contamination is one of the greatest threats to product quality, safety and compliance. Even the smallest bacterial buildup in process connections can lead to costly downtime, product recalls and regulatory violations. The challenge is keeping the entire process environment ultra-clean and secure—especially at connection points where contamination can quickly occur. Tri-Clamp® fittings provide a proven solution, using a sanitary, crevice-free design that’s easy to clean, quick to assemble and fully compliant with industry regulations. As a leader in pressure and temperature instrumentation, Ashcroft has been trusted for over a century to deliver trusted instrumentation for critical process applications. Our expertise in hygienic measurement, combined with our conventional or inline style Tri-Clamp connections, helps manufacturers maintain sterility while keeping operations efficient. In this article, you’ll discover why Tri-Clamp connections are preferred for hygienic processes, how they outperform threaded fittings in sterile environments, and the best practices for selecting and installing gaskets to ensure long-term reliability.
