Abstract

Se describen detectores de nivel de líquido. Un nivel de líquido ejemplificativo (100) incluye una carcasa (102) y un brazo (104) que se extiende a través de la carcasa (102). Un ensamble de palanca (200) está acoplado al brazo (104) y la carcasa (102), y el movimiento del brazo (104) provoca que el ensamble de palanca (200) abra o cierre un interruptor (202) mediante un campo magnético cuando un líquido alcanza un nivel predeterminado.
