The 440 Series of modular signal conditioners is a flexible, compact solution for acceleration, sound pressure, and force sensor signal conditioning. The modular architecture allows great flexibility and scalability for users who may add or change testing capabilities in the future. The system adds or varies capability by the selection of signal conditioning modules that conform to the 440 series standard for form factor, power consumption, and digital communication. Chassis themselves can be linked together, further expanding the system's scalability.

The PCB Series 440 Modular System is a versatile sensor signal conditioning and channel management system. The system is compatible with piezoelectric charge, ICP®, TEDS, and PCB capacitive sensors. It can be configured into a single signal conditioner such as a charge amplifier or it can be expanded into a multi-channel signal conditioning and channel management system. Since all signal conditioner modules are compatible, adding new modules is easy and economical.
