DLVR Series Low Voltage Digital Pressure Sensors Features 0.5 to 60 inH2O Pressure Ranges 3.3V Supply Voltage Standard / 5V Option I2C Standard Interface / SPI Interface Option Better than 1.0% Accuracy Over Temperature Typical Applications Medical Breathing Environmental Controls HVAC Industrial Controls Portable/Hand-Held Equipment General Description 2 TM The DLVR Series Mini Digital Output Sensor is based on All Sensors CoBeam Technology. This reduces package stress susceptibility, resulting in improved overall long term stability. The technology also vastly improves position sensitivity compared to single die devices. The supply voltage options ease integration of the sensors into a wide range of process control and measurement sys- tems, allowing direct connection to serial communications channels. For battery-powered systems, the sensors can enter very low-power modes between readings to minimize load on the power supply. These calibrated and compensated sensors provide accurate, stable output over a wide temperature range. This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like. A protective parylene coating is optionally available for moisture/harsh media protection.
