Meeting Our Customers’ Requirements

RPS/DPS 8000 Trench Etched 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.

Incorporating the exciting new TERPS technology (Trench Etched Resonant Pressure Sensor) offers an order of magnitude greater performance over current technologies to provide the highest accuracy and stability sensor available.TERPS is a resonant silicon pressure sensor technology platform that provides an order of magnitude greater accuracy and stability than current pressure measurement technologies

It also significantly extends the pressure range capability conventionally associated with resonating pressure technology (RPT) sensors and enables robust packaging, suitable for harsh environments. The RPS/DPS 8000 resonant silicon pressure sensor is the first pressure sensor to incorporate GE's TERPS technology platform.
