Charge amplifiers for engine combustion analysis, 2-channel / 5064E

The amplifier modules of Type 5064E are microprocessor controlled 2-channel charge amplifiers with analog signal conditioning. The Types 5064Ex2 and 5064Ex3 include the function of automated sensor identification (PiezoSmart). These amplifiers enable the recording of sensor operating hours and pressure cycles when using PiezoSmart sensors. In addition they have the ability to determine when a cylinder pressure sensor is exposed to extreme operating conditions. Important information such as sensor operation hours, pressure cycles and pMax can be calculated and automatically saved to the TEDS (Transducer Electronic Data Sheet) located in the sensor connector. The recorded pMax values are classified in 6 different pressure ranges (100, 150, 200, 250, 300 and ≥300 bar) which give a clear indication of the sensor load profile during application.
