Pressure sensor for combustion analysis

Sensor ZI33

The industry benchmark in M12 spark plug sensors

The AVL sensor ZI33 is a spark plug with an integrated pressure sensor. It is the industry benchmark for research and development tasks in M12-sized spark plug bores. With a new and improved design, the spark function of this indicating sensor has an electric strength of 45kV and no eccentricity. This enables ignition to behave in the same manner as the original spark plug.

To maximize the strength of the insulator, an increased ceramic diameter and a completely new design of the sensor membrane is used. The insulator of the spark plug is manufactured by Bosch, and this robust combustion pressure sensor can also be equipped with SIC for SDM.
