電子壓力開(kāi)關(guān)如何工作？

電子壓力開(kāi)關(guān) 提供電子開(kāi)關(guān)輸出信號(hào)。 它們通常還產(chǎn)生與壓力成比例的附加模擬輸出信號(hào)。 電子壓力開(kāi)關(guān)在出廠時(shí)設(shè)置為最佳開(kāi)關(guān)點(diǎn)，或者由于集成顯示器和按鈕而可以在現(xiàn)場(chǎng)進(jìn)行編程。 它們的集成可編程邏輯允許根據(jù)應(yīng)用定制開(kāi)關(guān)點(diǎn)和輸出信號(hào)。

現(xiàn)代電子壓力開(kāi)關(guān)的眾多可編程功能包括遲滯、延遲時(shí)間、常閉或常開(kāi)和窗口功能。 它們還提供恒定的壓力讀數(shù)并指示開(kāi)關(guān)輸出是否處于活動(dòng)狀態(tài)。 IO-Link 技術(shù) 還可用于通過(guò)信號(hào)電纜進(jìn)行遠(yuǎn)程編程。

How does an electronic pressure switch work?

Have you ever wondered how an electronic pressure switch works? In this article, has enlisted the expertise of control instrumentation experts, Barksdale , to give a tutorial.

Pressure switches are one of the most commonly used fluid control components . We use them at home, in our refrigerators, dishwashers and washing machines. Whenever we handle a gas or liquid we almost always need to control the pressure.

Most of the time we never think about pressure switches. They just show up with such machinery as machines or machine tools. In this type of equipment, we depend upon pressure switches to act as safety devices, alarms, or as the control element within the system. But in most cases we give little consideration to this component when we make a purchase.

How do electronic pressure switches work?

Electronic pressure switches provide electronic switch output signals. They often also produce an additional analogue output signal proportional to the pressure. Electronic pressure switches are factory set to optimal switch points or are programmable on-site thanks to integrated displays and buttons. Their integrated programmable logic allows for the switch points and output signal to be tailored to the application.

Among the many programmable functions of modern electronic pressure switches are hysteresis, delay time, normally closed or normally open and window function. They also provide constant pressure readings and indicate whether the switch outputs are active or not. IO-Link technology can also be used for remote programming via the signal cable.

When to use an electronic pressure switch

Electronic pressure switches are suitable for applications that demand stability, multiple switch points and flexibility of control – such as for control and automated equipment . They are the desired choice for installations requiring flexible programming and adjustment, local indication display and extra analogue output signals.
