The Series 137B quartz, free-field, blast pressure pencil probes from PCB Piezotronics are improved for durability and alignment with a 40% lower parts count and 50% fewer internal connections. The pencil probes feature a fast microsecond response time, with resonant frequencies to 500 kHz. Integral microelectronics provide a high signal-to-noise ratio compared to silicon semiconductor sensing technologies, which require external amplification. The 5-V output signal can drive cable runs hundreds of feet in length to a safe zone for data acquisition. The probes are designed for a range of explosion, blast, and shock-wave testing. Applications include measuring blast pressure in free-field or closed bunker arenas to obtain peak pressure, total impulse, shock wave, and time-of-arrival measurements often used to study blast effects on structures, vehicles, and humans.

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.
