The traditional static calibration of pressure and temperature sensors struggles to address rapid environmental changes in industries like automotive and maritime. The EMPIR project (DynPT) has pioneered dynamic calibration methods, achieving traceability in pressure ranges of 5–30 MPa and temperatures up to 3000°C with uncertainties as low as 1%1.

  • Key Innovations:

    • Shock tubes and rapid shutter systems for µs-level response (KTH, RISE)1.

    • Fiber-optic pyrometers for 250 kHz frequency measurements in combustion environments (NPL)1.

    • New sensors resistant to 300 bar and 2000°C conditions (VTT MIKES)1.

  • Impact: These advancements enable real-time monitoring in engines, improving fuel efficiency by 10% and supporting stricter EU industrial standards.
