压力传感器和真空传感器用于测量向传感器压力输入端施加的压力。测量操作借助传感器内安装的压力测量单元实现，它将超压或欠压与当前环境压力进行对比，然后将偏差作为电信号输出。此外，还可使用压力或真空传感器检测施加的负压是否高于或低于定义的开关阈值。该信息作为二进制电信号输出，也可作为比例模拟信号或通过 IO-Link 作为数字测量值输出。

You will find the pressure sensors SDE5 in our Core Range as a low-cost alternative for quick and simple pressure checks. They are suitable for pressure and vacuum detection as well as for object detection via dust pressure. Other features of the pressure sensors SDE5 are selectable output functions, programming through teach-in and switching status indication by LEDs visible from all sides. The fastest switching point settings can be made at the touch of a button. Festo pressure sensors SDE5 are available as plug or cable versions and are very quick to install thanks to QS fittings and a linkable wall bracket.
Also included in the Festo Core Range are the pressure sensors SPAN, which are suitable for monitoring compressed air and non-corrosive gases. The measurement method is based on a piezoresistive measuring cell for relative pressure measurement. The pressure value is transmitted to the connected controller either as a switching or analogue signal or via IO-Link®. Pressure sensors SPAN are used for pressure monitoring, network and leak testing as well as object detection. The versatile installation options (front panel, thread and wall mounting, series mounting with mounting bracket) and the quick connector enable the pressure sensors to be installed quickly. The clear display and intuitive menu navigation are just as characteristic as the compact design.
In addition to the pressure sensors and vacuum sensors from our Core Range, we also have a wide variety of other products, including PE converters, pressure switches as well as pressure transmitters. What all our products have in common is a compact design, attractive prices and versatile operation. They are suitable for the precise measurement of vacuum and pressure values and thus meet the requirements of various industrial applications. The flexibility and user-friendliness of Festo pressure sensors and vacuum sensors are particularly impressive.
