Calibration of Pressure Sensor in Automobiles Based on ZMD Chip

Abstract:

Article Preview

In order to eliminate the negative effect of temperature to automobile pressure sensor whose environment temperature changes from-40°C to 130°C, a calibration circuit is designed based on ZMD chip. The temperature characters of this pressure sensor are: zero point linearly change with temperature at the rate-0.07mV/20°C; strain coefficient linearly change with temperature at the rate 3.27e-4/°C. After calibrated, the output of pressure sensor change only with pressure and the deviation value is from-0.48%FSO to +0.84%FSO,in the designing range ±2%FSO.
