FIELD: electricity.
SUBSTANCE: additionally introduced into the thermostatic controller circuit is a T-shaped resistive loop with thermosensitive resistance playing the role of a compensative temperature sensor. The thermostatic controller allows to compensate for the static error of resonator piezoelectric element steady-state temperature resulting from ambient temperature change and in consequence of non-concurrence of the spatial locations of the resonator piezoelectric element, the temperature sensor and the heating element.
EFFECT: reduction of static error of steady-state temperature and reduction of temperature instability of the fundamental frequency of the output signal of the generator with a single-stage thermostat to a level comparable to temperature instability of the fundamental frequency of the output signal of a generator with a double thermostat combined with smaller dimensions, lower consumed power and lower labour intensity of the thermostatic controller setup.
