Description
Areas of application
- Standard instrumentation for pressure measurement: Monitoring of steady pressures and dynamic processes (e.g. stall detection or blade profile pressures) on all our test rigs.
Functionality
-
Resistive pressure measurement: The stretching and compression of the pressure diaphragm causes a change in resistance, which is translated into a voltage signal
-
Piezoresistive pressure measurement: The deformation of the diaphragm also causes a change in electrical conductivity, which results in a greater change in resistance and increases the measurement resolution
Properties
-
Precise integration: Sensors are integrated and positioned by our in-house sensor workshop without influencing the geometry around them
-
Modular design: Steady pressure transducers can be flexibly adapted to different test rigs
-
Compact miniature sensors: High measuring accuracy for dynamic flow analyses
