Your safety is our mission

Our expertise ensures maximum system safety operation

Our expertise guarantees you maximum safety and maximum availability of your system. We have decades of experience and extensive know-how. Our expertise is based on certified safety engineers and management systems as well as long-standing, trusting partnerships with international test, certification and standardization bodies. On this basis, we have already installed over 10 million devices in safety applications.

Over 250 certified product lines

The most comprehensive range of devices for hazardous areas. Many of the devices have been developed using state-of-the-art technology in accordance with IEC 61508 SIL 2 and allow for homogeneous-redundant application up to SIL 3 in safety-instrumented systems.

At the same time, uniform operating and safety concepts deliver simplicity and therefore increased safety in terms of managing operations.

Leading the way in safety-related design

Maximum safety and reliability in operation are guaranteed through consistent compliance with guidelines and standards and the implementation of user-specific requirements (e.g. NAMUR).

At the same time, innovations such as the first Coriolis mass flow measuring device incorporating reliable two-wire technology are important milestones on the path to safer system operation.

Trend-setting, safety-related testing concepts

This includes, for example, Fieldcheck for the systematic testing of safety-instrumented flow systems with no need for dismantling, or the Liquiphant Fail Safe as a monitoring system.
