March 31, 2008, Depew, NY, USA – Series 137A Quartz, free-field, ICP^® blast pressure pencil probes from the Aerospace & Defense division of PCB Piezotronics (PCB^®) are designed for a broad 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.

Quartz, free-field, ICP^® blast pressure pencil probes have an extremely fast 1 micro-second response time, with resonant frequencies to 500k Hz. ICP^® technology features integral microelectronics that provides a high signal-to-noise ratio compared to silicon semiconductor sensing technologies, which require external amplification. The high-level 5 volt output signal is capable of driving cable runs hundreds of feet in length, to a safe zone for data acquisition. Sensors are frequency tailored to capture both peak pressure and total impulse calculations.
