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 offer a wide range of pressure and electrical connections to enable a level of customization for your specific 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 flexibility of the RPS/DPS 8100 Series offers a truly unique solution for high accuracy and high stability pressure measurement requirements.

(3)Voltage 0.4 to 0.8 V @ 25°C (77°F), typically –2 mV/°C
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 specification (see manual K0533 for details)
Supply Response
•TTL : Accurate to specification within
500 ms of supply switch on, overall operating temperatures
•CAN Bus/RS232/485/USB: Accurate to specification within 10 minutes of turning supply switch on
Electrical Protection
RS232/485/CAN Bus/TTL: Connecting Vsupply and GND between any combinations of pins on the connector will not damage the unit
USB: Complies with USB 2.0 peripheral specification.
Insulation
RS232/485/CAN Bus/TTL:
>100 Mohm @ 500 Vdc between all pins and case.
Performance
There are two levels of performance specification:
Standard and Improved
Specifications include combined effects of non-linearity, hysteresis, repeatability and temperature errors over the compensated temperature range and calibrated pressure range.

•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 fit algorithm and coefficient 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)
