mpx10 sensors 4 freescale semiconductor temperature compensation figure 2 shows the typical output characteristics of the mpx10 and mpxv10gc series over temperature. because this strain gauge is an integral part of the silicon diaphragm, there are no temperature effects due to differences in the thermal expansion of the strain gauge and the diaphragm, as are often encountered in bonded strain gauge pressure sensors. however, the properties of the strain gauge itself are temper ature dependent, requiring that the device be temperature compensated if it is to be used over an extensive temperature range. temperature compensation and offset calibration can be achieved rather simply with additional resistive components, or by designing your system using the mpx2010d series sensor. several approaches to external temperature compensation over both ?40 to +125 c and 0 to +80 c ranges are presented in application note an840. linearity linearity refers to how well a transducer?s output follows the equation: v out = v off + sensitivity x p over the operating pressure range ( figure 3 ). there are two basic methods for calculating nonlinearity: 1) end point straight line fit or 2) a least squares best line fit. while a least squares fit gives the ?best case? linearity error (l ower numerical value), the calculations required are burdensome. conversely, an end point fit will give the ?worst case? error (often more desirable in error budget calculations) and the calculations are more straightforward for the user. freescale?s specified pressure sensor linearities are based on the end point straight line method measured at the midrange pressure. figure 2. output versus pressure differential figure 3. linearity specification comparison pressure differential output (mvdc) 80 70 60 50 40 30 20 10 0 0 0.3 2.0 0.6 4.0 0.9 6.0 1.2 8.0 10 1.5 psi kpa span range (typ) offset (typ) v s = 3 v dc p1 > p2 -40 c +25 c +125 c linearity actual theoretical offset (v off ) max p op output (mvdc) pressure (kpa) 70 60 50 40 30 20 10 0 0 span (v fss )
