What are explosion-proof pressure switches?

Explosion-proof pressure switches are special pressure switches designed for use in potentially explosive atmospheres. Our DS5/DS5P pressure switches are designed to meet the requirements for Zone 2 as well as for the pressure ranges between vacuum and 5000 bar, making them ideal for the European market and applications in moderately vulnerable areas. They offer reliable shifting functions that work precisely and safely even under extreme conditions. 

How explosion-proof pressure switches work

Zone 2 explosion-proof pressure switches sense the pressure through a sensitive diaphragm; once the pressure reaches a preset threshold, an electrical signal is sent to the control system. Intrinsically safe circuits ensure that no sparks or heat are generated that could cause ignition in the explosive environment. The robust housing and the special materials also ensure safety. Thanks to these safety measures, they provide reliable protection in environments where explosive atmospheres can occasionally occur. 

Advantages of ATEX pressure switches

The DS5/DS5P series impresses with its high flexibility and adaptability. Whether it's the choice of pressure range, electrical connections or switching logic, these explosion-proof pressure switches can be perfectly tailored to your specific requirements. Among the features to highlight are: 

  • Versatile customization options: Choose from a variety of pressure and electrical connections, as well as switching functions, switching thresholds and interfaces. The switching logics (NO/NC/Window) and switching hysteresis are individually configured according to your specifications. 
  • Reliability and safety: The DS5/DS5P pressure switches are specially designed for safe use in Zone 2 and meet the strict European safety requirements. 
  • Modification options: Our pressure switches can be optimally integrated into existing systems through specific adjustments. This makes them particularly attractive for applications where standard solutions are not sufficient. 
  • Wide range of electrical interfaces: In addition to classic npn/pnp interfaces, our pressure switches also offer galvanically isolating interfaces, which provide additional safety and flexibility. 

Thanks to their high adaptability and reliability, they are an optimal choice for demanding applications, just like our pressure transmitters with explosion protection or the explosion-proof level sensors

Explosion-proof pressure switches: Areas of application

Our explosion-proof pressure switches of the DS5/DS5P series are ideal for applications in Zone 2 where a high level of safety is required. Here are some of the key applications where these pressure switches are particularly suitable: 

  • Chemical industry: Pressure monitoring and control of pressure processes in the vicinity of plants with explosive gases or vapors. 
  • Pharmaceutical industry: Ensuring process reliability in the production of drugs with flammable substances. 
  • Food & Beverage: Compliance with safety regulations when processing and filling products in potentially explosive atmospheres. 
  • Plant engineering and process automation: Integration with automated systems for safe operation in hazardous environments that occur infrequently and only for short periods of time.
