ICP is an acronym for "integrated circuit piezoelectric", and is a registered trademark of PCB Group, Inc.(1,603,466), parent company of PCB Piezotronics.
ICP identifies PCB sensors that incorporate built-in, signal-conditioning electronics. 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 readily transmitted, over ordinary two-wire or coaxial cables, to any voltage readout or recording device. The low-impedance signal can be transmitted over long cable distances and used in dirty field or factory environments with little degradation. In addition to providing crucial impedance conversion, ICP sensor circuitry can also include other signal conditioning features, such as gain, filtering, and self-test features. The simplicity of use, high accuracy, broad frequency range, and low cost of ICP accelerometers make them the recommended type for use in most vibration or shock applications. However, an exception to this assertion must be made for circumstances in which the... Read More
