ATEX Pressure Switches for Hazardous Areas
ATEX-approved pressure switches are essential for safe pressure control in hazardous environments. For OEM machine builders, they ensure compliance, reliability, and risk reduction in demanding applications.
The pressure switches from Trafag feature a robust design that ensures long-term operation in demanding environments. They are extremely resistant to vibrations and maintain their switching accuracy throughout their entire lifespan.
Sensor Technologies and Pressure Ranges
Different applications require different sensing technologies. The mechanical ATEX pressure switches offer three main types:
1. Bellows Technology
- Best for low to medium pressure ranges
- Enables small switching differentials
- Suitable for sensitive control applications
2. Membrane (Diaphragm) Technology
- Handles pressures up to 100 bar
- Strong resistance to overpressure
- Ideal for liquids and gases
3. Piston Technology
- Designed for high-pressure systems (up to 600 bar)
- Excellent durability under dynamic loads
- Common in hydraulic systems
