«Simple Apparatus» conformity to ATEX 904

Trafag‘s mechanical pressure switches offer high vibration resistance and switchpoint accuracy in combination with an extraordinary rugged design for years of maintenance-free operation in rough conditions. Different sensors based on bellow, membrane and piston principle cover a wide range of pressure ranges, media and load cycle profiles.

May be used as „simple apparatus“ in zones at risk of explosions
