Speaking of the pressure switch believe that we all know it, and also very familiar. These are due to the fact that its development direction will continue to move forward, although the forward, but its development trend is how, below we together to have a look at pressure switch development, what is the trend?
Because now the pressure switch is being developed and popularized, more and more people begin to use it and recognize it. This is also being used in the development trend of its development direction: sensor passive, structure combination, functional reuse and component standardization. Pressure switch in general is the use of pressure difference between the two pipelines to send messages,, when the series liquid tube at the two ends of the pressure difference increased (or lower) rather than the controller set point, sends a signal to control the reversing or monitoring lubrication system. Then open the valve, thereby reducing the pressure difference between the two end of the system, to achieve the normal operation of the system.
We'll look at pressure switch structure combination: pressure switch combination is electronic based micro power and miniaturization advantage, transformer more by way of combination of components in transformer, full closed combined electrical appliance, isolation knife combination of electrical appliances, reduce the occupied, reduce cost control of the project net all rights reserved, can also through the multiplexing function to promote the miniaturization and intelligentize of an appliance itself. A variety of programs in the play to their respective advantages, at the same time, in combination with each other, complementary advantages, in addition there will be a variety of independent and closed type current voltage transformer mix outside, I believe that in some time, is expected to appear LPCT/ROG-CT and optical version of a portfolio of current transformer.
Secondly we in functionally multiplexed pressure switch: multiplexing function is mainly make full use of the data sharing, single point test, can be more sharing, transformer and provide goose, RS485, Mu and so on different types of digital interface, for a variety of measurement and control devices to share, reducing the mutual sensor more repeat installation, equipment configuration is more compact.
Finally, we will look at its parts standardization, standardization is use transformer standardized components, versatility and interchangeability, as standard accessories "plug-in" installed in a variety of equipment, different manufacturers transformer can change and exchange.
This is the development and trend of pressure switch, in the coming days, pressure switch whether in performance, technology, and development will continue the development, there will be more people know. It used to it, will become more common.
