Descrição
LH/LHA 24 Series Intelligent defrosting vehicle separator
Under the severe weather such as frost,snow,rain,fog,the penetrating power of the light curtain is reduced then the defrosting function operates automatically , In normal working condition (no frost,snow,rain and fog), the heating system stay non-launching to prolong the working life of the system.
Features
- With Intelligent heating function,Defrost function starts automatically under severe weather to eliminate the block to light path from frost,snow,rain and fog;
- Aspheric surface optical lens totally eliminate spherical aberration,aberration and stray light;
- Build-in self-diagnostic function,detection output function and alarm output function;
- Light penetrability power(Receiving light intensity of receiver),directive function, easy for on-site installation and maintenances;
- RS485series communication meet customers’ different task requirement by initial setting and meanwhile acquire on formation on every light beam and system working status;
- Reliable separation for vehicles, the reliability is high to 99.9% under fine whether and not less than 99.5% even under rain snow or fog whether.
