Electronic pressure and vacuum switch LFDS701

differentialfor air

LFDS701 is widely used in vacuum pump control system of electric cars, diesel vehicle and gasoline vehicles. LFDS701 has internal MEMS pressure sensor, by collecting warming and comparing of pressure signal to realize the switch tube output of special pressure point. The product uses pressure sensor that is absolute pressure type, the accuracy will not affect by atmosphere, which can be used in any altitude. The product has differential output, which reduces the risk of lifespan cutting of controlled device for frequent action nearby critical point.
