Balluff's BES wear-free inductive sensors for potentially explosive areas can be installed in various Ex zones. Use in areas where an explosive atmosphere only occurs occasionally (Category 3G/3D). Also for use in potentially explosive facilities or spaces in Zone 1 (Category 2G/1D) – then in connection with NAMUR-compatible barriers and transformers. For flexible use, we offer a comprehensive portfolio of common sensor housings and thread sizes. Our sensors come with either hard-molded cables or plug connectors.

Applicable for zones 2G/1D and 3G/3D
Pressure-rated up to 500 bar
High temperature-rated up to 120 °C
Can be combined with NAMUR amplifier
Non-contacting and thus free from wear
Impervious to contamination
Short-circuit protected
