Dual-Mode Charge Amplifiers
Dual-mode charge amplifiers represent a versatile solution for both piezoelectric charge mode and ICP® sensors. Among the advanced features offered by models 443B01, 443B02 and 2775C are an ultra-low noise floor, sensor fault detection, overload detection, a built-in calibration reference signal, and an RS-232 port for seamless computer control. Notably, model 443B02 features a long discharge time constant selection, ideal for capturing quasi-static events lasting several seconds, a capability particularly beneficial for ballistics and ammunition testing applications. Model 2775C features AC, DC, and servo outputs.
Models 443B01 and 443B02 are integral components of PCB's Modular Signal Conditioning System, characterized by plug-and-play signal conditioning modules that effortlessly slide out of the chassis. Replacement modules can be quickly inserted and securely fastened in place, ensuring swift adaptability and ease of maintenance.
Highlights:
- Accepts charge and ICP® sensor inputs
- Front panel keypad and display for easy control
- Selectable low and high pass filtering
- Signal integration to velocity and displacement
