description: The types of force sensors were investigated for theirÂ  ability to operate at critically low and high temperatures. Particular attention was paid to the comparison between strain gauge and capacitive sensors. The effect of temperature on the measured capacitance was investigated, specifically on changes in membrane parameters, on changes in the dielectric constant between the electrodes, and on changes in the modulus of elasticity of materials. The obtained data set was processed in MathCAD system. For the projected capacitive force sensor, a connection diagram of electronic components was made, structural and circuit diagrams were developed, software was written, and an assembly drawing of the sensor was given. Arduino Nano, AD7746 and LCD LMO16L were chosen as the electronic base. It was considered how the temperature affects some or other parameters of the membrane and the elastic element of the capacitive force sensor and conclusions were made to eliminate these shortcomings.
