Stainless steel diaphragm-seal pressure gauges are essential instruments in industries where measuring the pressure of media that is corrosive, viscous, sedimentary, or hazardous is required. The diaphragm seal protects the pressure gauge from the process medium, extending the gauge's life and ensuring accurate readings. Here are some industries where these gauges are commonly used:
Chemical and Petrochemical Industries: For monitoring and controlling processes involving aggressive or corrosive substances. The stainless steel and diaphragm seal offer resistance to harsh chemicals.
Pharmaceutical Industry: In processes requiring high levels of cleanliness and sterility. The diaphragm seal ensures that the pressure gauge does not contaminate the process media.
Food and Beverage Industry: Used in applications where hygiene is paramount. The diaphragm seal prevents process media from entering the gauge, eliminating the risk of contamination.
Oil and Gas Industry: For measuring pressures in processes involving sour gas (H2S) and other corrosive substances. Stainless steel and the diaphragm seal help withstand the corrosive environment.
Water Treatment and Desalination Plants: In filtering and desalination processes where the medium may be corrosive or contain particulate matter that could clog or damage a traditional pressure gauge.
Biotechnology: In fermentation and other processes where the purity of the medium is crucial. The diaphragm seal allows for accurate pressure measurement without risking contamination.
Pulp and Paper Industry: For measuring pressure in processes involving corrosive liquids and slurries. The diaphragm seal helps protect the gauge from being clogged by paper pulp and other residues.
Semiconductor Manufacturing: In cleanrooms and processes where ultra-pure chemicals are used. The stainless steel and diaphragm seal prevent contamination of the delicate chemical processes.
Power Generation: For pressure measurement in processes involving corrosive gases and liquids. The durability and resistance of stainless steel and diaphragm seals are critical for safety and efficiency.
Environmental and Waste Management: In handling and treatment processes for hazardous or corrosive waste, where accurate pressure measurement is essential for safety and compliance.
BuoHuong Stainless steel diaphragm-seal pressure gauges are chosen for their durability, resistance to corrosion, and the ability to maintain purity and safety in sensitive and harsh environments, making them indispensable in these industries.
