Differential-Pressure Sensors Exhibit Long-Term Stability

Find more content on: Components

A company’s differential-pressure sensors consume little energy, making them suitable for long-term operation on battery power. Whereas the operational current of a standard sensor in the company’s general series can be as high as 6 mA, the CMOSens SDP6x6 low-power sensors in the SDP600 series, which enter sleep mode after each measurement is taken, are optimized for operating currents no greater than 400 μA. Current drain in sleep mode is less than 1 μA. Offering digital I2C output and full calibration and temperature compensation, the sensors exploit the principle of calorimetric flow measurement to achieve high sensitivity and accuracy even at pressure differences smaller than 10 Pa. They exhibit high long-term stability and are free from zero-point drift.
