Blast pressure sensor, Type 6233B

The Type 6233B… pencil probes are designed to measure highly dynamic pressures in free-field blast testing. An integrated amplifier circuit (IEPE) converts the charge signal from the quartz sensing elements into a voltage output.

Application: Pencil-type blast sensors are most effectively used in testing scenarios where the direction of shock wave propagation is clearly defined. The side-on measurement is least affected by reflections and superpositions of pressure waves.

Technical data:

• Measuring range: 1000 psi.
• Sensitivity: 200…5 mV/psi.
• Natural frequency: ~300 kHz.
• Linearity: ≤±1 %FSO.
• Operating temperature range: –55°C … 125°C.
