Specification notes (cont.):3. Total accuracy is the combined error from offset and span calibration, linearity, pressure hysteresis and temperature effects.4. The sensor is calibrated with a common mode pressure of 1 bar absolute. Due to the mass flow based measuring principle,

variations in absolute common mode pressure need to be compensated according to the following formula:

∆Peff = True differential pressure

abssensoreff P

bara 1PP ×∆=∆ ∆Psensor = Differential pressure as indicated by output voltage

Pabs = Current absolute common mode pressure5. The max. common mode pressure is 2 bar.6. Figure based on accelerated lifetime test corresponding to 1 year of life.7. For example with a LBAS500... sensor measuring CO2 gas, at 4.5 V output the actual pressure will be 500 Pa x 0.56 = 280 Pa.
