PERFECCIONAMIENTOS EN EL CONTROL DE NIVEL PARA EL LIQUIDO DEFRENOS EN VEHICULOS AUTOMOVILES

摘要

PTC resistor level sensor for brake fluid for a working temperature range of -40 DEG to +150 DEG C and voltage fluctuation of 9 to 15 volts at 12 volts reference voltage with a PTC resistor element (2) with a narrowly matched, specific resistance and with an envelope (8) which is only slightly bigger in surface than the PTC resistor element (2).
