The Series 113B and 102B frequency tailored integrated circuit piezoelectric (ICP) and charge output piezoelectric pressure sensors from PCB Aerospace & Defense have a 1 µs response time, with resonant frequencies above 500 kHz. Frequency tailoring, a combination of mass balancing and microelectronics, provides a fast response to shock waves without the high ringing amplitudes experienced with other technologies. The ICP technology provides a high signal-to-noise ratio compared to resistive silicon semiconductor sensing technologies. The 5-V output signal can drive cable runs of hundreds of feet in length, to a safe zone for data acquisition. The sensors feature dynamic ranges to 15 kpsi and sensitivities to 100 mV/psi. Applications include measuring blast over-pressure and explosion pressure, pulsations, closed bomb combustion, airbag testing, as well as pneumatic, hydraulic, fluid, and other dynamic pressures.

Industrial aluminum slabs are typically produced by blending small amounts of copper or manganese in a reservoir of molten aluminum that is rapidly cooled, a process known as direct-chill casting. Variations in the way these elements solidify can yield uneven results that weaken the final product.
