Background. The research subject is a linear displacement transducer for measuring systems of rocket-and-space equipment. The purpose is engineering and research of the linear displacement transducer that operates in openspace.
Materials and methods. We worked out a block scheme and a linear displacement transducer configuration on the basis of linear variable differential transformer, made a linear displacement transducer LDT, andprovided specification of the engineered sensor.
Results. The research describes LDT design features that stability of the device against to environmental conditions, introduces gauge line and accuracy of the LDT.
Conclusions. The obtained specification and operating characteristics of the engineered linear displacement transducer satisfy the requirements set for the sensors operating in the open space
