TERPS Technology

TERPS (Trench Etched Resonant Pressure Sensor) Technology

TERPS (trench etched resonant pressure sensor) technology is Druck’s market-leading, proprietary pressure sensing technology, that offers unrivalled accuracy, stability and precision specification when utilised in Druck’s pressure sensor, calibrator, controllers, and pitot static testers.

Through rigorous comparative testing spanning nearly a decade, it is proven that TERPS technology provides customers with unique unrivalled stability (low drift), accuracy, robustness, and speed in combination.

In like-for-like comparisons, Druck’s pressure portfolio enabled with TERPS performance can achieve more than 10x more accuracy and 10x more stable than traditional silicon-based sensing technologies. Other available pressure measurement technologies such as quartz, film, or optical pressure do not compare to TERPS.

What is TERPS technology?

Known to be an innovator and industry leader for over half a century, Druck is known for not compromising the performance of our pressure sensors, calibrators or controllers. This is achieved through a strong focus on quality, design expertise and customer experience.

Not compromising means customers don’t need to make trade-offs when choosing pressure devices. The utilisation of TERPS technology in Druck’s pressure portfolio means customers across a wide range of applications, including some of the world’s harshest industries, can be sure of the performance of TERPS technology.

TERPS Applications

Building on the tried and tested industrial sensing, test and calibration and aerospace pressure portfolio, TERPS technology enables increased accuracy, longer calibration intervals and long term stability for applications including:

Aero ground testing
Hydrology and oceanography
Level monitoring - tidal, ballast tanks, tsunami detection
Barometers and weather stations
Turbine controls and optimisation
World class accuracy and stability means less maintenance and less downtime for calibrations
