Pressure Transducers

Industrial Dynamic Pressure Sensors for Harsh Environments

IMI Sensors, offers a comprehensive range of dynamic pressure sensors designed for demanding industrial applications. Our pressure sensors are engineered to accurately detect dynamic pressure fluctuations, pulsations, and turbulence—even in extreme high static pressure environments.

Common applications for IMI dynamic pressure sensors include:

  • Combustion instability and combustion dynamics monitoring
  • Performance analysis for hydro-turbines, steam turbines, and gas turbines
  • Pressure fluctuation detection in compressors, pumps, pipelines, and hazardous areas

IMI's robust pressure sensors provide reliable solutions for monitoring critical dynamic pressure events across energy, power generation, and industrial markets. Built to withstand harsh conditions, our sensors deliver accurate, dependable performance where it matters most.

High-Performance ICP® Pressure Sensors for Dynamic Applications

ICP® pressure sensors feature integrated electronics that convert high-impedance signals into robust, low-impedance outputs. Our advanced piezoelectric pressure sensors are uniquely designed to detect rapid pressure spikes, pulsations, and surges with exceptional sensitivity. They also accurately measure minute pressure changes even under extremely high static pressure conditions.

Ideal for dynamic pressure monitoring, ICP® pressure sensors are commonly used in applications such as:

  • Surge detection
  • Pulsation and spike monitoring
  • Leak detection
  • Combustion instability analysis
  • Acoustic measurements in compressors, pumps, pipelines, and gas turbines

Designed for versatility, these sensors are compatible with ICP® signal conditioning equipment and support cost-effective, 2-wire cable systems. Thanks to their low-impedance output, our pressure sensors deliver reliable, high-quality signal transmission over long cable runs—even in harsh, dirty environments—without degradation.
