8200/8300
High Accuracy Resonant
Pressure Sensor for
Harsh Media
For over 40 years, Druck has manufactured
precision pressure sensors with a capability to
meet critical applications in industrial, aerospace,
oil and gas, and research environments. Today,
Druck is part of GE Measurement & Control and
has continually worked to develop and improve on
the performance of our pressure sensors to meet
customer’s requirements.
The RPS/DPS 8200/8300 moves the exciting new
TERPS technology into harsh media environments.
TERPS is a resonant silicon pressure sensor
technology platform that provides an order of
magnitude greater accuracy and stability than
current pressure measurement technologies
available. The new TERPS technology also extends
the pressure range capability to high pressures
and by incorporating true pressure media isolation
greatly improves its suitability for use in harsh
environments.
By packaging TERPS technology in Hastelloy C276,
the RPS/DPS 8200/8300 allows for use in harsh
corrosive media such as sea water, or sour gas.
The combination of the power of the TERPS
technology and the quality, reliability and exibility
of the RPS/DPS 8000 Series oer a truly unique
solution for high accuracy and high stability
pressure measurement requirements.

.
For Frequency & Diode output the above accuracies are
achievable by using a polynomial curve t algorithm and
coecient data supplied with sensor.
Sensors are calibrated against standards traceable to
UKAS operating to better than 100 ppm.
