Safety and reliability for complex processes

Solutions for the Chemical and Pharmaceutical Industry

Meeting maximum requirements

The chemical and pharmaceutical industries have some of the most stringent requirements for safety, environmental protection, and traceability. Our solutions are based on a wealth of experience and deep understanding of functional safety and hazardous area protection requirements. Our concepts address the specific demands of both plant operators and users.

Our benefits for the chemical and pharmaceutical industry

Securing power, signal, and data transmission for maximum plant availability and efficiency in the system.



From process data through to intelligent data-based services for zoned and non-zoned areas.



Comprehensive certification solutions such as G3 coating, SIL3, Atex, UL&CSA, IECEx, and GOST.



Universal conversion platforms for legacy DCS migration solutions for signal packing, marshalling, and distribution.



From robust and secure site monitoring over remote and local diagnostics to secure networks to the cloud.

Your challenges - our answer:

Explosion protection

Klippon® Protect enclosures have been specially developed for the challenging environmental conditions of the chemical industry. They are therefore certified according to the latest international standards for operation in gas and/or dust-laden environments. We manufacture junction boxes for power and signal distribution or data networks according to your individual requirements. In addition, we develop certified local control centre systems which combine a variety of control and automation functions in a single enclosure.

Corrosion protection

The robust Klippon® enclosure range stands out with its great durability and corrosion resistance. The range of enclosures extends from glass fibre reinforced polyester to high quality electropolished stainless steel. We also provide a comprehensive range of electronic components with corrosion-resistant G3 coating to increase the lifetime of your equipment and systems.

Functional safety

Many of our products have been specifically optimised for use in safety systems to ensure functional safety. Our safety relays combine reliability and convenience with superior application characteristics. These include high switching capacities, comprehensive line and load monitoring, and much more. We also offer a complete range of analogue signal conditioners suitable for use in SIL-classified signal circuits.

Asset management

The demand for smaller maintenance teams and shorter downtimes makes asset management a challenge. This is particularly important when a plant site has multiple assets from different manufacturers that are at varying stages of their lifecycle. Weidmüller's AML software enables a proactive approach to optimising maintenance and quality to ensure efficient use of resources. When a control system needs to be upgraded, Weidmüller's migration solutions enable a fast and reliable migration to the latest generation of PLC and control systems. This shortens downtimes and relieves employees.


In today's chemical and pharmaceutical industries, state-of-the-art automation systems are the key to greater business success. U-Mation from Weidmüller is the solution-oriented approach to plant automation. The portfolio includes a complete range of products from controllers and hot-swappable I/O systems to HMIs and SCADA systems.


As a partner in Industrial Connectivity, Weidmüller has developed many innovative connectivity solutions. This tradition continues with our Managed Ethernet portfolio. It enables end-to-end connectivity from the sensor to the cloud and ranges from unmanaged and managed switches to wireless LAN and bridge units and GSM-enabled communication solutions.

Product highlights for the chemical and pharmaceutical industry:


Safety relays up to SIL3 according to EN 61508.

Whether for a burner control system, secure emergency shut down or, for example, for pump controllers – our safety relay guarantees safe conditions and convince with superior and significant features.Their integration into distributed control systems (DCSs) is even better, with an input filter which makes the SIL circuit immune to the test impulse which is typically used by a DCS. You will also benefit from simple maintenance: the fuses are accessible from the outside and can easily be changed. You can see the status of the safety and the monitoring devices clearly with status LED on the device. All devices are accredited though certification by the internationally recognised TÜV-NORD group – for secure process applications around the globe.

Analogue signal conditioning

Weidmüller's range of analogue converter and monitoring relays makes it a powerful partner in light of the increasing use of automation.

Considering the increase of automation, isolating amplifiers are required which convert, isolate, monitor, protect and visualise your digital and analogue signal values from industrial and process automation, e.g. temperature, pressure, level, flow volumes, weight, and speed.

Our signal converters for DC standard signals, 4-20 m A and 0-10 V isolating amplifiers, switching amplifiers, frequency converters, and threshold switches are characterised by a high level of accuracy, universality and a wide assortment of variants.

Analogue signal conditioning
