A141 Charge Amplifier for Piezo Electric sensors
When it comes to special applications with limited installation space, or high surface or ambient temperature, PE (Piezo Electric) sensors are the best choice. With their direct charge output (physical unit pC/g) these sensors do not have any electronic items in the sensor housing, making them small and robust against high temperatures. However, these sensors require external signal conditioning to convert the charge into a standard voltage signal. In the past, this conversion was achieved with external devices, e.g., inline charge amplifiers, and their output was connected to a data acquisition system.
With the Q.series X A141 charge amplifier, we provide a four-channel signal conditioning I/O module that covers the need for external devices.
Depending on the charge signal to be measured, you can choose between two modes for either fast transient and pulsating signals or almost static ones. Every time you are facing a broad measurement range, the A141 might be a perfect choice. Use it for measurement challenges involving accelerometers, force, or pressure sensors.
