RPS/DPS 8000
High Accuracy Resonant
Pressure Sensor
Since 1972, 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 Oil & Gas and has continually worked
to develop and improve on the performance of
our pressure sensors to meet our customers’
requirements.
The RPS/DPS 8000 is the rst product to
incorporate the exciting new TERPS technology.
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.
Features:
• High Precision, ±0.01% FS over compensated
temperature range
• High Stability, ±100 ppm FS/year
• Wide temperature range, up to -40°C to +125°C
(-40° to 257°F)
In addition to providing the performance and
packaging improvements available with TERPS,
the RPS/DPS 8000 product line takes advantage
of best practices to oer a wide range of pressure
and electrical connections to enable a level of
customization for your specic requirements never
before available in the performance class of this
sensor.
The combination of the power of the TERPS
technology and the quality, reliability and exibility
of the RPS/DPS 8000 Series oers a truly unique
solution for high accuracy and high stability
pressure measurement requirements.
• Media isolated construction, suitable for use in
harsh environments
• Multiple Output congurations, RS-232, RS-485,
USB 2.0, CAN Bus, Frequency & Diode (TTL)
• Wide selection of pressure & electrical
connections to suit specic requirements
Specications
Measurement
Base Pressure Ranges
• 0 to 2 bar (0 to 30 psi) absolute
• 0 to 7 bar (0 to 100 psi) absolute
• 0 to 14 bar (0 to 200 psi) absolute
• 0 to 20 bar (0 to 300 psi) absolute
• 0 to 35 bar (0 to 500 psi) absolute
• 0 to 70 bar (0 to 1000 psi) absolute
Note: Values in psi are approximate.
The base range selected is the next range up from
the requested calibrated range.Units are converted to
bar for selection; e.g., 30 psi = 2.07 bar. A 7 bar base
pressure range will be selected.
Calibrated Ranges
Any zero-based range between 1 and 70 bar (14.5 to
1000 psi) can be specied. (Performance will be of the
full scale of the base pressure range selected.)
Barometric ranges are available in the RPS/DPS 8100
series. The lowest calibrated pressure is 35 mbar
absolute.

Performance
There are two levels of performance specication:
standard and Improved
Specications include combined eects of non-linearity,
hysteresis, repeatability and temperature errors over
the compensated temperature range, and over the base
pressure range of 35 mbar to the full scale pressure.
Accuracy Code Precision
A1- Standard 0.02% FS
A2- Improved 0.01% FS
• 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.
Compensated Temperature Ranges:
There are four compensated temperature ranges
available:
-10 to +50°C
-40 to +85°C
-40 to +125°C (TTL and CAN bus only)
-55 to 125°C (TTL and CAN bus only)
Temperature Eects
All temperature eects are included in the accuracy
statement.
Long Term Stability
Standard: ±0.02% FS/annum
Improved: ±0.01% FS/annum
Note: Unless otherwise specied, specications are at the
reference conditions of 25°C (77°F) ±5°C (±9°F) and 1 bar
(14 psi).
