A protective sleeve system featuring a housing having an inner cavity adapted to hold a vial. The conduits are interposed between an air intake and a mixing zone delivering mixed air. This is achieved in that the amplitude of this electrical voltage signal is represented by the period of a delay between the activation of the supply voltage for the sensor device and the output of the first valid measurement value. The invention further relates to parts of such plants, including the parts of such plants. The transition device and modified section are also configured to interact with the cables of the High Tension Cable Barrier to transfer and spread the collision load from the high tension cables to the Metal Beam Guide Fence.
