MPX2010 DP differential pressure transducer A) physical model and B) connections. Reproduced with permission. Copyright Freescale Semiconductor, Inc. 2004 - 2011. All Rights Reserved. The MPX2010DP differential pressure transducer from Freescale Semiconductor© is a temperature-compensated piezoresistive pressure sensor which provides a very accurate and linear output voltage proportional to the applied pressure in the range of 0 – 10 kPa. The recommended voltage supply is 10V, and the error and linearity figures are specified for 10V. However, the MPX2010DP is a ratiometric device; that is the maximum output voltage depends on the reference voltage which means that a different supply may be used so long as the reference voltage is very stable.
