Pressure sensors and vacuum sensors are used to measure the pressure applied to the pressure input of a sensor. This is done using a pressure measuring cell integrated in the sensor, which compares the excess pressure or low pressure with the prevailing ambient pressure and outputs deviations as an electrical signal. A pressure or vacuum sensor can also be used to detect whether an applied negative pressure is above or below a specific switching threshold. This information is output as a binary electrical signal, but can also be output as a proportional analogue signal or as a digital measured value via IO-Link®.

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.
压力传感器 SPAN 同属 Festo 核心产品范围，适用于监控压缩空气和非腐蚀性气体。测量方法是基于压阻式测量单元测量相对压力。压力值以开关或模拟量信号形式，或者通过 IO-Link 传输到所连接的控制器。压力传感器 SPAN 可用于压力监控、网络和密封测试以及物体检测。该压力传感器采用快速连接技术，安装方式多样，可进行前面板安装、螺纹和壁挂安装、采用固定支架的排式安装等，由此实现快速、便捷的安装过程。一目了然的显示界面和直观的菜单导航，与紧凑型结构一样颇具特色。
