PCB Piezotronics has advanced the free-field, series 137B quartz, blast pressure pencil sensors, based on ICP technology, with enhanced life-span and improved configuration by reducing interior interfaces by 50% and parts count by 40%.
These unique sensors exhibit ultra-speed response time in µs and features 500k Hz resonance frequencies. These particular blast probes are ideal for blast, shock wave and explosion testing. The varied applications of these pressure probes encompass evaluation of the explosion pressure in closed bunker zones or free-field to achieve entire impulse, shock wave, intense pressure and time-of-arrival calibrations for analyzing the consequences of the blast on vehicles, humans and other infra-structures.
The ICP technology is reinforced on integrated microelectronics that supplies an intense signal-to-noise proportion in comparison with the silicon semiconductor sensor technologies, which demands exterior amplification. The intensive output signal in the order of 5 V drive wires that stretches to many feet in length, and relays it to a secure area for information processing. These sensors are frequency customized in such a way as to trace the total impulse as well as the peak pressure readings.
PCB Aerospace and Defense have broad expertise in developing solutions and programs for serving civil and military aviation, homeland security, global aerospace, test and calibration markets and defense.
