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 oer a wide range of pressure

and electrical connections to enable a level of

customization for your specic 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 oers 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 congurations, RS232, RS485,

USB 2.0, CAN Bus, Frequency & Diode (TTL)

• Wide selection of pressure & electrical

connections to suit specic requirements

• Low acceleration eects

Performance

There are two levels of performance specication:

Standard and Improved

Specications include combined eects 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 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 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

specication (see manual K0533 for details)

Supply Response

• TTL : Accurate to specication within 500 ms of supply switch on, overall operating temperatures

• CAN Bus/RS232/485/USB: Accurate to specication within 10 minutes of turning supply switch on
