How does an electronic pressure switch work?

你有沒有想過 電子壓力開關 是如何工作的？ 在本文中， 征集了控制儀表專家 Barksdale 的專業(yè)知識來提供教程。 壓力開關 是最常用的 流體控制元件 之一。 我們在家中、冰箱、洗碗機和洗衣機中使用它們。 每當我們處理氣體或液體時，我們幾乎總是需要控制壓力。

我們的家用電器不要求高精度，也不會經(jīng)歷高循環(huán)率。 相比之下，工業(yè)機械和系統(tǒng)中使用的壓力開關必須堅固、可靠、準確并具有較長的生命周期。

大多數(shù)時候，我們從不考慮壓力開關。 他們只是帶著機器或機床等機械出現(xiàn)。 在此類設備中，我們依靠壓力開關充當安全裝置、警報器或系統(tǒng)內(nèi)的控制元件。 但在大多數(shù)情況下，我們在購買時很少考慮這個組件。

電子壓力開關如何工作？

電子壓力開關 提供電子開關輸出信號。 它們通常還產(chǎn)生與壓力成比例的附加模擬輸出信號。 電子壓力開關在出廠時設置為最佳開關點，或者由于集成顯示器和按鈕而可以在現(xiàn)場進行編程。 它們的集成可編程邏輯允許根據(jù)應用定制開關點和輸出信號。

現(xiàn)代電子壓力開關的眾多可編程功能包括遲滯、延遲時間、常閉或常開和窗口功能。 它們還提供恒定的壓力讀數(shù)并指示開關輸出是否處于活動狀態(tài)。 IO-Link 技術 還可用于通過信號電纜進行遠程編程。

何時使用電子壓力開關

電子壓力開關適用于需要穩(wěn)定性、多個開關點和控制靈活性的應用，例如 控制和自動化設備 。 它們是需要靈活編程和調(diào)整、本地指示顯示和額外模擬輸出信號的安裝的理想選擇。

BPS3000 電子雙壓力開關

在開創(chuàng)固態(tài)壓力開關四分之一個世紀后，我們最近推出了下一個改變游戲規(guī)則的產(chǎn)品： BPS3000 電子雙壓力開關 。 這種數(shù)字壓力開關代表了壓力開關發(fā)展的下一步，并具有一些真正令人印象深刻的屬性。

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.
