High Frequency Pressure Sensors

ICP® Free-field Blast Pressure “Pencil” Probe Series

The Pencil Probe is designed to measure shock waves caused from explosions in air. Such explosions are found in the industries of Defense and Mining, or wherever explosives research is conducted.

Series 137B pencil probes incorporate acceleration-compensated quartz sensing elements and integral ICP® microelectronics that assist driving the blast signal over long cables, with improved stability and durability.

Series 137B quartz, free-field, ICP® blast pressure pencil probes are offered with both 10-32 coaxial jack and BNC electrical connectors. New to the series are two-sensor probes that allow an easy way to capture shock speed close to the explosion. The pencil probes continue to feature an extremely fast microsecond response time, with resonant frequency above 400kHz.

Highlights:

  • Ranges from 50 to 1000 psi (344 to 6,895 kPa)
  • Rise time < 4 µsec
  • Resonant frequency ≥ 400 kHz
  • The new 137B25 features two sensing elements in the same housing
  • 137B32 features an active sensor in the front and a placebo in the rear
