Introduce method for fabrication of low temperature resistant meteorological sensor

this sensor is used in space environment control system

diffused silicon piezoresistive chip

TO—8 socket and encapsulation with silicon gel

it is small and light

it has strong ability to adapt to harsh environment

and temperature range of- 55

95 ℃. Test results show that the sensor has good performance of high and low temperature at room temperature static state

even more superior than international products. Fabrication process is simple

low cost

and it has very high practical value.
