Accelerometers:

PCB® offers a vast selection of accelerometers to accommodate anything from routine measurement tasks to extraordinary testing requirements. Whether it’s a cell phone quality assurance test or continuous monitoring of an aircraft engine, we can help, with sensors which are off-the-shelf or custom designed for a specific application.

What are ICP® sensors?

Integrated Circuit Piezoelectric (ICP®) sensors contain built-in microelectronic signal conditioning circuitry – yet operate over just two wires. This circuitry requires constant current excitation and serves to convert the high-impedance charge signal generated by the piezoelectric crystal into a low-impedance voltage signal, for ease of signal transmission and analysis. Low-cost coaxial or two-wire cables may be utilized with ICP sensors. Signal fidelity is relatively unaffected by contamination or moisture. ICP sensors offer trouble-free operation in dirty, industrial environments or submerged in liquids. Generally, ICP sensors are more cost effective and easier to use than charge output piezoelectric sensors; however, their temperature range is limited by the survivability of the built-in microelectronic circuitry.
