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.
