A pneumatic control system works with compressed ambient air, the so-called compressed air service. Since pneumatic control systems are very resistant to external environmental influences, they can be used in many different application areas.
Using air as the working medium is the technical basis of pneumatics. Compressed air is used to transmit and control energy in pneumatic applications. Controllers are composed of a power unit and a control system. The control system registers all operations and processes them. The output signals that are transmitted during processing control the behaviour of the drive elements that are connected to the controller. Compressed air motors or compressed air cylinders are examples of drive elements.
Control system: Pneumatic control systems offer a number of different benefits, in part because air as a working medium inherently poses few risks and is not very costly. The following list provides an overview of the most important benefits:
Especially when compared to a hydraulic solution, pneumatic systems and control systems are often more advantageous since compressed air is usually available in production facilities anyway and pneumatic systems – once the operating element has been actuated – do not require air recirculation.
Pneumatic control systems that use air are often also more reliable than electromotive control technology that relies on electricity.
Pneumatic control technology and an appropriate pneumatic system are used in many industries and sectors for all sorts of applications. Different versions of the systems are used, for example, to support machine tools, automatic production lines, lifting tools or mechanical clamps. Here is an overview of common application areas:
Pneumatic control systems can also be used in water supply, in train doors or even in nuclear research. These control systems have changed the way many companies do business. Many industries, such as manufacturing or transportation, are able to operate more efficiently thanks to the availability of compressed air.
气动计数器适合安装在前面板，可通过气动方式复位。可以选配保护帽，用于计数至预选值或连续添加计数。计数器从零开始增加气动信号，在达到预选数字后发送气动输出信号。在按下白色锁止键的同时键入预选值，即可完成计数器预选（预选数字一直显示在预选窗口中）。重置计数器时，会保留预选数字。在运行过程中也可以对预选值进行修正。已完成的件数和已结束的时间单元，无需回溯即可读取。
这款气动定时器是实现切换延迟的理想选择。计时器配备一颗调整螺栓、一个视觉显示器。计时器在设定的延迟时间结束后，将施加在第一个接口的输入压力切换到第二个接口。复位模块用于在预选时间结束后自动复位 PZVT-...-SEC 型定时器，并出于控制目的生成一个指定长度的输出信号。拉动复位模块的设置按钮，可以手动复位计时器。得益于此，可以通过自动重复的时间间隔轻松实现气动时间控制。
