Pressure sensor is immune to electrical noise

Paul Boughton
The use of highly-sensitive piezoelectric combustion pressure sensors with built-in ground isolation can largely avoid the effects of electrical interference. Kistler's new sensor Type 6125C... offers combustion pressure signals with high degree of noise immunity

Isolation of the sensing element prevents the generation of electrical noise and allows interference-free measurements, even if potential differences exist between the engine and the measuring system. The Kistler Type 6125C... is the third generation of a combustion pressure sensor with built-in ground isolation.

The use of a new Kistler Piezostar crystal has made it possible to increase the sensitivity to –37pC/bar and the pressure range to 300bar. This innovative sensor ensures precise and reliable measurement data even under electrically noisy testing conditions.

Mounting dimensions for the new unit are compatible with its predecessor, the Type 6125B...
