NAGANO KEIKI Twin needle pressure gauge (vertical/embedded type) 100Φ Model number: GD11/GD16

- The two concentric rotating pointers allow you to easily compare and read the pressure at two locations. - The number of pressure gauges required for display can be reduced, allowing for more efficient use of installation space.
This pressure gauge can measure pressure at two locations simultaneously within the same instrument. It is mainly used in places where the installation space is limited, or when you want to compare pressure at two locations. For example, in the case of a railway vehicle, the pressure inside the air tank and the brake cylinder can be read simultaneously on the same scale plate.
*When selecting a pressure gauge, please select a pressure range so that the upper limit of normal pressure falls within the following range to ensure that the gauge can perform to its full potential. For constant pressure: 3/4 or less of the maximum pressure range For fluctuating pressure: 2/3 or less of the maximum pressure range Also, please confirm that the materials of the wetted parts listed are suitable for the gas or liquid to be measured. For details, please refer to JIS B 7505-1.
