Laboratory charge amplifiers, 1-channel, low noise, measuring ranges ±2 to ±2200000 pC, freq. range ≈0 … 200 kHz / 5018A

The Type 5018A is the successor to the Type 5011B charge amplifier. The operating modes are Short, Medium, Long and DrCo (drift compensation). Drift compensation will be applied when measuring the cylinder pressure to compensate any occurring drift. The charge amplifier is available in different versions with automated sensor identification PiezoSmart and voltage input for sensors with integrated Piezotron circuit. When using PiezoSmart, the individual sensor parameters of the measuring chain are set automatically. The main element of PiezoSmart is an electronic data sheet called TEDS (Transducer Electronic Data Sheet) which is attached to the sensor. This TEDS chip contains all the essential data of an individual pressure sensor. Another feature is the ability to determine when a cylinder pressure sensor is exposed to operating conditions. When utilized in conjunction with a PiezoSmart sensor, important information, such as pressure cycles and run time, can be calculated and automatically saved to the TEDS chip. This information can be used as part of a resource management program to determine calibration frequency and inventory control.
