Relative Pressure Sensor RPS 0-0.6

GRUNDFOS DATA SHEETRPS 0-0.6Relative Pressuresensor Standard, 0-0.6 barFig. 1 RPS sensorTechnical overviewGrundfos Direct Sensors™, type RPS, is a series of combined pressure and temperature sensors (two-in-one) designed for high-volume production. The RPS sensors are fully compatible with wet, aggressive media and are available for pressure ranges of 0-0.6 up to 0-16 bar (relative pressure).The RPS sensor utilises MEMS-sensing technology in combination with a novel packaging concept using corrosion-resistant coating on the MEMS sensor element. This makes the RPS sensor very robust and ideal for high-volume OEM applications.The trademark Grundfos Direct Sensors™ is owned and controlled by the Grundfos Group.Applications• domestic hot-water system efficiency • water level in central heating system• dry-running protection in solar systems and gas boilers• monitoring of pressure and temperatureFeatures• pressure ranges: 0-0.6; 0-1.0; 0-1.6; 0-2.5; 0-4; 0-6; 0-10 and 0-16 bar.• voltage output (ratiometric, ideal for use with microcontroller) • compact and robust mechanical design• approved for potable water: WRAS, KTW, W270, ACS.Benefits• pressure and temperature sensor in one package (two-in-one sensor) • compatible with wet, aggressive media• accurate, linearised and temperature-compensated pressure sensor• fast temperature response (direct media contact)SpecificationsIf the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.TM03 8138 0607PressureMeasuring range (relative) 0 to 0.6 barAccuracy (±1s), 25 to 80 °C ±2% FSAccuracy (±1s), 0 to 100 °C ±3% FSResponse time < 0.5 sResolution 5 mbarTemperatureMeasuring range 0 to 100 °CAccuracy (±1s), 25 to 80 °C ±1 °CAccuracy (±1s), 0 to 100 °C ±2 °CResponse time(63.3 % at flow velocity > 2 m/s) < 1.5 sResolution 0.5 °CMedia and environmentMedia The sensor is compatible with liquidsMedia temperature (operation) 0 to 100 °CMedia temperature (peak) –25 to 120 °C, non-freezingAmbient air temp.
