Pressure sensor for combustion analysis

Sensor GU21D

The industry benchmark in M7 thermodynamic analysis sensors

The M7-size AVL sensor GU21D is a precise thermodynamic measurement solution for when a smaller thread diameter than M8 is required. It is equipped with a sensor identification cable (SIC) for sensor data management (SDM) and its split mounting thread reduces negative influences such as mechanical stresses from the mounting bore.

An integrated heat-conduction element ensures excellent thermal coupling of the piezoelectric crystal elements to the cylinder head. This minimizes negative thermal effects and ensures robust, accurate performance from this benchmark thermodynamic analysis solution.

Ideal for applications where maximum efficiencies and optimization are required. The GU21D is an indicating sensor that enables a highly detailed level of insight into engine cylinder performance.
