Amphenol / PCB Piezotronics 482A16 Single-Channel Line-Operated Signal Conditioner

The Amphenol/PCB Piezotronics 482A16 is a single-channel, line-operated signal conditioner designed for ICP accelerometers and microphones. It supplies regulated constant current to power compatible sensors and converts their high-impedance outputs into low-impedance signals compatible with standard measurement instrumentation. Adjustable gain and integrated filtering enable signal optimization for vibration analysis and acoustic measurement applications.
