Vacuum sensors
Electronic vacuum sensors from ifm electronic are used for pressure measurements below atmospheric pressure. But many of these units do not only measure vacuum but also positive pressure. They have, for example, a measuring range from -1 to 10 bar.

The sensors are available either with or without display for use in hygienic or non-hygienic applications. They are either based on the ceramic-capacitive or piezo-resistive measuring principle.

Typical applications include pressure monitoring on vacuum pumps or vacuum grippers. The units are designed for use in industrial applications, i.e. they measure low vacuum (down to -970 mbar).

All units have robust housings with no moving parts such as pistons or springs. Thus, the sensors are extremely shock and vibration resistant and operate without any wear or maintenance.

The tried and tested ceramic-capacitive measuring principle is corrosion-resistant and long-term stable. This ensures consistent and long-term accuracy of the measured values. The measuring cells used are particularly resistant to dynamic pressure peaks, which ensures high overload protection.

Units based on piezo-resistive technology have been design-optimised for pneumatic systems. They feature a configurable 2-colour display to easily visualise when a vacuum exceeds or drops below a set value.
