Background. The purpose of the work is a determination to capacity to work of the sensor of the linear displacement working in condition of the lowered pressure by way of modeling of the heat processes and experimental determination to additional inaccuracy from influence of the lowered pressure.
Materials and methods. Organized modeling in the manner of heat model of the heating element to designs of the sensor from diffused powers of electronic components. The Executed piece of evidence result modeling and estimation to capacity to work of the sensor in condition of the influence of the lowered pressure on importance of additional inaccuracy.
Results. The brought results calculation diffused powers electronic components and modeling by heat flap at influence of the lowered pressure on sensor of the linear displacement. 3D-model of the sensor is designed. Experimental is confirmed correctness of the constructive decisions of the sensor. Additional inaccuracy of the sensor is determined from influence of the lowered pressure.
Conclusions. The results of modeling and experiment have confirmed capacity to work of the sensor in condition of the influence of the lowered pressure.
