RPS/DPS 8100
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 8100 incorporates 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.
In addition to providing the performance and
packaging improvements available with TERPS,
the RPS/DPS 8100 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 8100 Series oers 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, ±50 ppm FS/year (typical)
• Wide temperature range, up to -55 to +125°C
(-67 to 257°F)
• Multiple Output congurations, RS232, RS485,
USB 2.0, CAN Bus, Frequency & Diode (TTL)
• Wide selection of pressure & electrical
connections to suit specic requirements
• Low acceleration eects

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 calibrated
pressure range.
Accuracy Code Precision
A1- Standard 0.02% FS
A2- Improved 0.01% FS
• For barometric ranges with improved accuracy,
precision is ±0.1 hPa max.
• 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)
Response Time
• TTL Output:
<25 ms for pressure change from 10% to 90% FS
• RS232/485/USB Output:
Dependent on the output update rate which is set by
the user with a minimum of 500 ms
(see manual K0473 for details)
• CAN Bus:
Dependent on the output update rate which is set by
the user with a minimum of 10 ms while maintaining
specication (see manual K0533 for details)
Supply Response
• TTL : Accurate to specication within
500 ms of supply switch on, overall operating
temperatures
• CAN Bus/RS232/485/USB: Accurate to specication
within 10 minutes of turning supply switch on
Temperature Eects
All temperature eects are included in the accuracy
statement.
Long Term Stability
Standard: ±0.02% FS/annum max.
Improved: ±0.01% FS/annum max. (±0.005% FS typical)
Note: Unless otherwise specied, specications are at the
reference conditions of 25°C (77°F) ±5°C (±9°F)
