Pressure and vacuum sensors

Pressure sensors SDE and vacuum switches for controlling all pressure values: programmable or as a modular product

Efficient and reliable pressure and vacuum monitoring and control combined with flow monitoring are of the utmost importance when pneumatic systems are used for automation.

These sensors broaden the range for which systems can be used, offer more safety and also provide the option of remote maintenance and monitoring. Quick and simple to operate thanks to the uniform control and display concept utilized with all of Festo’s pressure sensors.
