| Abstract: | Pressure characters of hydraulic supports and work circumstance of sensor are analyzed, and technique requirement are suggested. Based on the principle of piezoresistance effect, piezoresistive pressure sensor is designed. The temperature compensation is elaborated in detail in zero drift and sensitity drift aspects. And the static performance analysis to the sensor is made. |
