The function of a diaphragm seal is to prevent the fluid from coming into direct contact with the instrument. This prevents the instrument from being damaged by obstruction or erosion caused by corrosive, dirty, viscous, or crystallizing fluids or gases.
DS200 series is a double-flange type where the diaphragm is located on the upper flange. The diaphragm size is not affected by the size of process connection flange, making it more suitable for low-pressure ranges.
