在液压试验台或比较精密的液压系统中,要求十分精确地测量系统压力,这就需要对压力进行分级测试,即使用两个或两个以上不同量程的压力表进行压力测试。这样就要求在系统压力比较高时关闭量程较小的压力表。如果使用ZBK-60型自动压力表开关就能在测量过程中省略这一步。
In hydraulic test rigs or more sophisticated hydraulic systems, the need to measure the system pressure very accurately requires a pressure rating of two or more pressure gauges with different ranges. This requires the system pressure is relatively high when the pressure gauge is closed smaller range. If you use the ZBK-60 automatic pressure gauge switch can be omitted during the measurement step.
