RPS/DPS
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 oer a truly unique

solution for high accuracy and high stability
pressure measurement requirements.

Features:

• High Precision, ±0.01% FS over compensated

temperature range

• High Stability, ±100 ppm FS/year

• Wide temperature range, -40°C to +125°C (-40°F
to 257°F)

• Media isolated construction, suitable for use in

harsh environments

• Multiple Output congurations, RS-232, RS-485,
Frequency & Diode (TTL)

• Selection of pressure & electrical connections to
suit specic requirements

Specications include combined eects of non-linearity,

hysteresis, repeatability and temperature errors over the
compensated temperature range, and over the pressure

range 35 mbar to the full scale pressure.

.

For Frequency & Diode output the above accuracies are

achievable by using a polynomial curve t algorithm and
coecient data supplied with sensor.

Sensors are calibrated against standards traceable to

UKAS operating to better than 100 ppm.

Compensated Temperature Ranges:

There are three compensated temperature ranges
available:

-10 to +50°C

-40 to +85°C

-40 to +125°C
