Sensirion's ASP1400 differential pressure sensor sets standards for offset free and highly accurate measurement of small differential pressures. The sensor measures a mass flow passing through the sensor and is calibrated for differential pressure. With its leading CMOSens® Technology for superior performance, the ASP1400 digital differential pressure sensor is optimized for ultra-low differential pressures, best accuracy and long-term stability. With its ASF1430 Sensirion, also offers a similar sensor calibrated for mass flow.
