The 3-level pressure sensors for modern AUTOMOTIVE AIR CONDITIONERS have vast advantages over the old 2-level ones.
The incorporation of a third level of pressure in the AIR CONDITIONING SENSOR provides us with greater security, avoiding failures of the air conditioning due to overpressure, which is very common in 2-level sensors.
There are many brands that have incorporated this type of pressure sensor in their automotive air conditioners: Toyota, Hyundai, Kia, JAC motors, Lexus, Isuzu, Acura, Honda
