Hydrogen Focused 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 Baker Hughes and has continually worked to develop and improve on the performance of our pressure sensors to meet our customers’ requirements. The RPS/DPS8000H combines ground-breaking TERPS technology and a hydrogen barrier coating to create the most accurate and stable hydrogen-capable pressure sensor on the market today. TERPS is a resonant silicon pressure sensor technology platform that provides an order of magnitude greater accuracy and stability than current pressure measurement technologies. 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. • Media isolated construction, suitable for use in harsh environments Challenges in hydrogen pressure measurement As a market leader in pressure measurement for the past 50 years, Druck is fully aware of the challenges that hydrogen applications pose for pressure sensors due to the unique behaviour of the medium. Exposure to hydrogen gas can impact the performance of a pressure sensor, specifically via the processes of hydrogen permeation and embrittlement, hence key design aspects need to be considered with a hydrogen pressure sensor to maintain accuracy and stability. In addition to providing the performance and packaging improvements available with TERPS, the RPS/DPS8000 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/DPS8000H Series offers a truly unique solution for high accuracy and high stability pressure measurement in a hydrogen-rich media. • 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) • Suitable for use in hydrogen rich media • Multiple Output configurations, RS-232, RS-485, USB 2.0, CAN Bus, Frequency & Diode (TTL) • Wide selection of pressure & electrical connections to suit sp
