Pressure transmitters are used in a wide range of industries, especially in industry. Due to the complexity and diversity of the measuring medium of pressure transmitters, many situations require certain corrosion resistance of pressure transmitters. The housing, process connection and diaphragm of the pressure transmitter are made of stainless steel, and the measuring medium should be compatible with 304 and 316 stainless steel. The vast majority of stainless steels have good corrosion resistance, and when the number of chromium atoms in the steel is not less than 12.5%, the electrode potential of the steel can be abruptly changed, and the electrode potential can rise from negative potential to positive electrode potential. Prevents galvanic corrosion. 304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm3, and is also called 18/8 stainless steel in the industry. High temperature resistance of 800°C, with good processing performance and high toughness, it is widely used in industrial and furniture decoration industries and food and medical industries. 304 stainless steel is widely used in the manufacture of equipment and parts that require good overall properties (corrosion resistance and formability). 316 stainless steel is the second most widely used steel grade after 304. Mainly used in the food industry, watches and accessories, pharmaceutical industry and surgical equipment, the addition of molybdenum element makes it obtain a special structure that resists corrosion. Because it has better resistance to chloride corrosion than 304, it is also used as “marine steel”. SS316 is commonly used in nuclear fuel recovery units. Grade 18/10 stainless steel is also generally suitable for this application class. The measuring medium of the pressure transmitter must be compatible with its material, and the pressure transmitter must be replaced immediately if it is found to be incompatible. For some special measurement media, the star instrument can be customized to meet the needs of customers under different working conditions.
