The safety and high efficiency of production.If marking out the normal range (NR) of surveyed parameter in pressure and temperature instrument at the scene,
Meter reading personnel can be made quickly to judge very much parameter current whether in normal range (NR), if exceeding normal range (NR), then meter reading
Personnel can respond at the first time, effectively avoid all kinds of accidents generated because response speed is slow.
The pressure and temperature instrument with over range alarm function on the market is all made of in the lower bound region of dial plate at present
The method distinguished with high limit region with different colours, when the disadvantage of the method maximum is that lower bound region and high limit region are factory
Just be solidificated on instrument board, the later period be in it is nonadjustable, cause every kind of instrument that can only use in fixed place, if
Want that limitation is very strong, and the instrument of each position is both needed to independent standard with then warning region that will be no longer appropriate for elsewhere
Standby standby, increases the stock-sales ratio of industrial processes standby, so that industrial cost is increased, therefore, we
It is proposed a kind of limit value adjustable type instrument structure.
