6052CU20

The Kistler 6052CU20 is the heavy-duty (U20) version of Kistler's Type 6052C high-temperature piezoelectric cylinder pressure sensor. It has a reinforced diaphragm, which Kistler recommends for measurements mainly in the knock range or at very high peak pressures. Like every 6052C it is very small and is installed front-sealed in an M5 x 0.5 bore. Kistler names cylinder heads with tight geometry, motorcycle and small engines, and in-vehicle combustion analysis as its main uses.

The U20 measures 0 to 300 bar (350 bar overload) with a sensitivity of about -18 pC/bar and is calibrated over 0-100, 0-200 and 0-300 bar. The 6052C family keeps its sensitivity within +/-0.5 % between 150 and 250 C. Kistler's patented passive acceleration compensation reduces the effect of engine vibration. Kistler rates the sensor for hydrogen combustion engines.

The sensor has an integral cable, either PFA with steel braiding as standard or oil-tight FPM, and a KIAG M4 x 0.35 connector. It feeds a charge amplifier or indicating system. Kistler's uncooled-sensor manual covers the bore, mounting, cable routing and the borescope and reaming checks of the sealing face. The 6052C is a current Kistler product (data sheet revision 04.26).
