Vacuum sensors

Vacuum sensors with ceramic measuring cell

Due to an optimised support in the process connection the units with a ceramic measuring cell are designed for highest stress with nominal pressures of -1 to 600 bar. These sensors are extremely robust against mechanical influence and work completely without wear and tear or fatigue. The resulting long-term stability ensures safe operation and reliable measurement results over 100 million pressure cycles.

Vacuum sensors with silicon measuring cell

As regards accuracy, the units with the piezoresistive silicon measuring cell are every bit as good as the sensors having used a ceramic measuring cell so far. Thanks to their construction they allow differential pressure measurements without having to connect a second pressure pick-up.

System solutions

In addition to the wide range of pressure sensors ifm also provides special and reliable system solutions. Special units, based on our tried-and-tested pressure sensors, permit use in even more applications. Using the PC-based communication and software solutions, use of the ifm pressure sensors is even more comfortable.
