Model No. GD1_ Duplex Pressure Gauge
This pressure gauge features two pressure connections to measure simultaneously two different pressures for limited space instead of installing two pressure gauges. It can be used for railway application to measure both air tank pressure and break cylinder pressure with one indicator.
Feature
・Features two pointers to read two different pressures for easy comparison
・Saves space and number of pressure gauges where there is limited space
＊To maximize performance, select full scale pressure range to indicate normal operating pressure which comes to conditions below.
For constant pressure : The maximum operating pressure should not exceed three-quarters of the full-
scale range.
For fluctuating pressure: The maximum operating pressure should not exceed two-thirds of the full-scale
range.
Select appropriate wetted parts compatible with process fluid (gas and liquid) which the gauge will be
subjected.
Please refer to JIS B 7505-1 for details.
