ATEX-Pressure Switches for Demanding Environments

ATEX-approved 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.

The mechanical switches utilize three different technologies: bellows, membrane, and piston.

  • Bellows switches are suitable for low to medium pressures where small switching differentials are desired.
  • Membrane switches are designed for pressures up to 100 bar and are resistant to overpressure, making them ideal for measuring liquids and gases.
  • Piston switches are built for pressures up to 600 bar and are also resistant to overpressure.
