Explosion & Blast Pressure Sensors intended for High Output Measurements

Tue, 11/02/2010 - 6:10am


The Series 137B quartz, free-field, ICP blast pressure pencil probes from PCB Piezotronics (PCB) have been improved for durability and alignment by lowering the parts count by 40% and internal connections by 50%. The pencil probes continue to feature an extremely fast micro-second response time, with resonant frequencies to 500k Hz. The new Series 137B quartz, free-field, ICP blast pressure pencil probes 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.

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 long 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. For technical information, please contact Bob Metz, Product Manager, telephone 866-816-8892, e-mail:
