Improving Turbocharger Test Accuracy with TERPS® DPS 8000 Pressure Sensors

Challenge

Turbocharger development plays a vital role in improving engine performance, fuel efficiency, and emissions. As these targets become more demanding, the need for highly accurate and reliable measurement data becomes increasingly critical.

On turbocharger test rigs, pressure measurement is a key parameter influencing design optimisation and validation. However, traditional sensing technologies can limit the level of precision and stability required for next-generation development—particularly in high-performance test environments.

Solution

To address these challenges, the manufacturer has implemented Druck DPS 8000 pressure sensors for critical measurements on its turbocharger test rigs.

The DPS 8000 series is powered by TERPS® (Trench Etched Resonant Pressure Sensor) technology—Druck’s advanced resonant silicon sensing platform. This technology delivers a step-change in accuracy and long-term stability compared to conventional pressure measurement technologies.

In addition to enhanced accuracy, the TERPS® platform provides:

Exceptional long-term stability, reducing drift and recalibration requirements Robust performance in demanding environments, through improved media isolation and sensor design High precision measurement capability across a wide pressure range These characteristics make the DPS 8000 ideally suited for high-precision test and development applications.

Results

By deploying DPS 8000 sensors at critical test points, the manufacturer has improved the accuracy and reliability of pressure measurement data used in turbocharger development.

This enhanced performance supports:

More confident design decisions Greater consistency in test results Continued improvements in efficiency, performance, and emissions

The stability and precision enabled by TERPS® technology ensure that measurement data accurately reflects system performance—supporting ongoing innovation in engine development.
