The numerical value of display is not equal to the pressure value of current fluid), generally we are straight by ordinarily manometer when using pressure gauge
It connects and is contacted with measured node, is closer when operator operates with measured node, but for some chemical industry, super-pressure etc.
Under environment, operator can not closely and testee contact, or need to the frequent prolonged pressure prison of some fluid
Control, it is time-consuming and laborious according to the mode of manual measurement, it is therefore desirable to a distance type pressure gauge with monitoring function is designed,
It can be transmitted on remote monitoring platform by the pressure value that pressure gauge is surveyed in wireless telecommunications.
Summary of the invention
In view of the above deficiencies, the present invention provides a kind of distance type pressure gauge with monitoring function, can it is remote and
The pressure value of prolonged measurement testee, monitors pressure value, while whether can monitor pressure gauge in real time
State in normal work.
The present invention is achieved by the following technical solutions: a kind of distance type pressure gauge with monitoring function, including pressure
