Oil Sensor Exploration
Today's oil drills must drill far down into the earth in their
search for oil. As they drill down deep into the earth, through rocks
and dirt, the temperature of the drill increases. Oil workers worry that
the oil drill's bit will become too hot and break. To prevent that from
happening, these oil drill bits often have a temperature sensor built
inside of them. When the temperature reaches a dangerous level, that is,
a level that could break the drill bit, the sensor sends an electronic
signal to the oil workers to stop drilling.
