Kistler Instruments' new Type 601A miniature pressure sensor, available in both charge output and voltage (IEPE) output types, is well suited to a wide variety of dynamic pressure measurement applications. The high sensitivity of the PiezoStar crystal developed by Kistler, much higher than that possible with quartz, allows small pressure fluctuations which are superimposed on static pressures to be measured with exceptional resolution. In addition to the high sensitivity and small size, the charge output version has a wide operating temperature range from -196 to + 350degC at pressures up to 250 bar. The C601A also benefits for a high natural frequency (>215kHz), making it suitable for applications with dynamic pressure events.
