When an incorrect switch point becomes expensive

From bag detection in filling plants to pressure monitoring in fire suppression systems: Our switches and sensors secure processes where an incorrect switch point becomes expensive.

Developed and manufactured in Nufringen.

The switch point must fit the application

When pressure monitoring is safety-relevant, an off-the-shelf solution is often not enough. It is crucial that the pressure switch fits the application exactly, both technically and functionally. This is precisely what our products are designed for: switch points that remain within the tolerance window even after thousands of cycles, configured for real operating conditions.
