Characteristics and Performances of Thick Film Pressure Sensors for Automotive Applications

Taking advantage of thick film resistors piezoresistive properties, a certain number of pressure sensors has been developed for automotive applications.

The main applications are related to manifold pressure measurements in ignition and injection electronic systems for conventional and turbocharged engines, in oil and air monitoring systems for cars and heavy trucks, in diagnosis benches.

The new developed sensors fulfil the requirements for low cost, high performances and high reliability necessary in today automotive electronic control systems. On the other side they can also successfully replace the mechanical and conventional pressure sensors (i.e. LVDT, potentiometric) already used in the above mentioned applications.
