This pressure gauge can measure and indicate pressure at two locations simultaneously within the same instrument. It is used when installation space is limited, or to compare pressure between two systems. It is also known as a “train gauge” because it is generally used for braking railway vehicles. It can also be used as a differential pressure gauge by reading the pressure difference between the two systems from the two concentric rotating pointers.
