Abstract
Sensors with a frequency output signal are marked as particularly high accuracy, it is easy to switch, and signals
may be transmitted over long distances. The main element of such sensors is an electromechanical oscillator connected to the
feedback of the autogenerator. String metal oscillators do not provide the required measurement accuracy due to unsatisfactory
elasticity, hysteresis, relaxation, and drift of characterisrics. The creation of oscillators made of quartz and silicon due to the
perfection of these materials, is difficult. Tere exist the technological problems and problems of conjugation of temperature
coefficients of materials expansion. It is proposed a quartz sensor without an oscillator, made from the quartz and equipped by
optoelectronic means.
