Capturing Transient pressure Changes with High Fidelity

For industries where pressure fluctuates rapidly, obtaining accurate real-time measurements presents a challenge. Whether monitoring pressure waves, reciprocating pumps or engine combustions, specialized instrumentation is necessary to resolve these dynamic process variables.

The Requirements of Dynamic Measurement

Key attributes for such applications include:

1. Wide bandwidth up to 200kHz for capturing pressures changing within milliseconds
2. High natural frequency over 1MHz for minimal signal distortion
3. Fast rise time under 1μS for resolving pressure wave fronts

Technology: Piezoresistive Pressure Sensing

Commonly employed are piezoresistive sensors, utilizing semiconductor strain gages integrated with high-speed conditioning circuitry. Measuring resistance changes proportional to applied pressure allows true dynamic readings.

Optimized for Transient Needs

Dedicated dynamic instruments called high response pressure transducers optimize piezoresistive technology further with bandwidths exceeding 200kHz and rise times under 1μs.

Applications From Research to Production

Areas served include engine development, explosions studies, pump performance testing and industrial process control systems requiring precision dynamic pressure data.
