Conversion to Physical Values 5.1 Signal scaling and physical unit The calibrated signal read from the sensor is a signed INTEGER number (two's complement number). The INTEGER value can be converted to the physical value by dividing it by the scale factor (pressure = sensor output scale factor). The scale factor is specified in Section 2. 5.2 Temperature compensation The SDP600 sensor series features digital temperature compensation. The temperature is measured on the CMOSens® chip by an on-chip temperature sensor. This data is fed to a compensation circuit that is also integrated on the CMOSens® sensor chip. No external temperature compensation is necessary. 5.3 Mass flow temperature compensation A sensor output proportional to mass flow is necessary for measuring mass flow in a bypass configuration. Even though the output of the SDP sensors with mass flow temperature compensation is still differential pressure, the temperature compensation is adapted especially for mass flow measurements in a bypass configuration. At calibration temperature both calibrations are equivalent. Please find the application note “Bypass Configuration Differential Pressure Sensor SDPxxx” on our website. 5.4 Altitude correction The SDP600 sensor series achieves its unsurpassed performance by using a dynamic measurement principle. The applied differential pressure forces a small flow of gas through the sensor, which is measured by the flow sensor element. As a result, any variation in gas density affects the sensor reading. While temperature effects are compensated internally, variations in atmospheric pressure (elevation above sea level) can be compensated by a correction factor according to the following formula: DPeff = DPsensor (Pcal / Pamb) DPeff: Effective differential pressure DPsensor: Differential pressure indicated by the sensor Pcal: Absolute pressure at calibration (966 mbar) Pamb: Actual ambient absolute pressure. Altitude correction factors: Altitude [meters] Ambient pressure (Pamb) [mbar] Correction factor (Pcal / Pamb) 0 1013 0.95 250 984 0.98 425 966 1.00 500 958 1.01 750 925 1.04 1500 842 1.15 2250 766 1.26 3000 697 1.38 Example: At 750 m above sea level and a sensor reading of 40 Pa, the effective differential pressure is 41.8 Pa. Note: In many HVAC applications such as air flow measurement in a bypass configuration, the described dependence on absolute pressure is actually welcome because the quantity that must effectively be controlled is the mass flow and not the volume flow. Mass flow is dependent on differential pressure and absolute pressure. For details please refer to our application note “Measuring Flow in a Bypass Configuration”. 6. OEM Options A variety of custom options can potentially be implemented for high-volume OEM applications. Contact Sensirion for more information. |
