Pressure sensor with 0.01% precision that does not drift more than 100 ppm per year. Druck’s new resonance technology TERPS is available in pressures up to 70 bar with isolation membrane.

DPS/RPS 8000 TERPS Pressure Sensor

DPS/RPS 8000 is the first product to use Druck:s, exciting new TERP technology. TERP is a resonant silicon pressure transducer technology that provides greater accuracy and stability than other available pressure measurement techniques.TERP technology is suitable for use in harsh environments and contexts. The digital sensor DPS has an RS232 or RS485 interface and the RPS provides a direct pulse output for further signal processing together with temperature data

 

DPS/RPS 8100 TERPS Pressure Sensor

For lower pressures there is the DPS/RPS 8100 which does not have an isolation membrane and is therefore suitable as a barometer or applications where g-force can affect the measurement.

DPS/RPS 8200/8300 TERPS Pressure Sensor

DPS/RPS 8200/8300 has Hastelloy C as material in the parts affected by the media, alternatively completely in Hastelloy to cope with environments with aggressive media, e.g. acidic environments or seawater.
