How does an electronic pressure switch work?

你有没有想过 电子压力开关 是如何工作的？ 在本文中， 征集了控制仪表专家 Barksdale 的专业知识来提供教程。 压力开关 是最常用的 流体控制元件 之一。 我们在家中、冰箱、洗碗机和洗衣机中使用它们。 每当我们处理气体或液体时，我们几乎总是需要控制压力。

我们的家用电器不要求高精度，也不会经历高循环率。 相比之下，工业机械和系统中使用的压力开关必须坚固、可靠、准确并具有较长的生命周期。

大多数时候，我们从不考虑压力开关。 他们只是带着机器或机床等机械出现。 在此类设备中，我们依靠压力开关充当安全装置、警报器或系统内的控制元件。 但在大多数情况下，我们在购买时很少考虑这个组件。

电子压力开关如何工作？

电子压力开关 提供电子开关输出信号。 它们通常还产生与压力成比例的附加模拟输出信号。 电子压力开关在出厂时设置为最佳开关点，或者由于集成显示器和按钮而可以在现场进行编程。 它们的集成可编程逻辑允许根据应用定制开关点和输出信号。

现代电子压力开关的众多可编程功能包括迟滞、延迟时间、常闭或常开和窗口功能。 它们还提供恒定的压力读数并指示开关输出是否处于活动状态。 IO-Link 技术 还可用于通过信号电缆进行远程编程。

何时使用电子压力开关

电子压力开关适用于需要稳定性、多个开关点和控制灵活性的应用，例如 控制和自动化设备 。 它们是需要灵活编程和调整、本地指示显示和额外模拟输出信号的安装的理想选择。

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.
