PCB Piezotronics (PCB) is proud to announce the launch of the new model 113B55 ICP free-field explosion blast pressure “lollipop” sensor. The “lollipop” configuration offers a unique advantage over traditional pencil probes by eliminating the pointed tip, allowing blast waves to travel across its surface from any elevation. This design minimizes sensitivity to elevation, ensuring more consistent and reliable performance. The sensor is also shorter in length than most pencil probes.
Model 113B55 features:
- Not elevation dependent
- Micro-second rise time
- >500 kHz resonant frequency in the reflected
- Obtains peak pressure, total impulse, shock wave, and time-of-arrival
ICP technology features integral microelectronics that provides a high signal-to-noise ratio compared to piezoresistive 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.
Model 113B55 is designed for a broad range of explosion, blast, and shock wave testing applications including 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.
