HAEHNE Ex-Protection Sensors are supplied as complete measuring system consisting of the following components: sensor, J-Box, safety barriers and the associated measuring amplifier. Sensor and measuring amplifier  receive the order option F. Each measuring system consists of firmly assigned components. In the case of orders containing more than one measuring system, it is prohibited to exchange individual components among themselves.
The force measurement sensors for the use in potentially explosives atmospheres are developed and manufacted in accordance with the harmonized European standards for electrical apparatus for potentially explosive atmospheres:
EN 60079-0:2012 + A11:2013 (General requirements) and
EN 60079-11:2012 (Intrinsic safety "i").
