The Oil-filled stainless steel pressure gauges we made are commonly used in various industries due to their durability and the ability to dampen the effect of vibration and pulsation, which enhances the accuracy and longevity of the gauge. Here are some industries where they are widely used:
Oil and Gas Industry: For monitoring pressure in drilling, extraction, and refining operations. Their robustness makes them suitable for the harsh conditions of oil fields.
Chemical and Petrochemical Industries: These gauges are used in processes that involve corrosive substances and extreme temperatures, where precise pressure monitoring is crucial.
Water Treatment and Sewage Plants: They are used to monitor water pressure in pipes and tanks, ensuring the proper operation of filtration systems and pumps.
Food and Beverage Industry: In applications that require cleanliness and non-contamination, such as in the production and processing of food and beverages. The stainless steel construction is ideal for maintaining hygiene.
Pharmaceuticals: Similar to the food and beverage industry, the pharmaceutical industry requires equipment that maintains the purity of products. These gauges can withstand sanitization processes without corroding.
Pulp and Paper Industry: For monitoring pressure in the various stages of paper production, including cooking, washing, and bleaching processes, where chemical resistance and durability are needed.
Marine and Offshore: In ships and offshore platforms, these gauges are used for monitoring systems like hydraulics, fuel, and water treatment due to their resistance to corrosion from saltwater environments.
HVAC (Heating, Ventilation, and Air Conditioning): Used in systems requiring precise control of air and fluid pressure to operate efficiently and safely.
Manufacturing and Machinery: In hydraulic and pneumatic systems to ensure equipment operates within safe pressure ranges, preventing machinery failure and downtime.
Our gauges are valued across industries for their reliability, accuracy, and ability to perform in demanding environments, making them a preferred choice for pressure measurement solutions.
