Glossary definition of 'ICP'ICP is an acronym for "Integrated Circuit Piezoelectric", and is a registered trademark of PCB Group, Inc. ICP transducers incorporate built-in signal-conditioning electronics and are used to measure dynamic pressure, force, strain, and acceleration. The built-in electronics convert the high-impedance charge signal that is generated by the piezoelectric sensing element into a usable low-impedance voltage signal that can be transmitted over ordinary two-wire or coaxial cables over long distances with little degradation. ICP sensor circuitry can also include other signal conditioning features, such as gain, filtering, and self-test features.
The electronics within ICP accelerometers require a constant-current regulated, DC voltage source. This power source is sometimes built into test equipment to allow the direct connection of ICP devices and is sometimes referred to as ICP Power.
