INSTALLATION AND THERMOSTAT FOR MONITORING LONG-TERM STABILITY OF FREQUENCY OF QUARTZ RESONATORS AND GENERATORS Russian patent published in 2022 - IPC H03B5/32 

FIELD: instrument engineering.

SUBSTANCE: inventions relate to the field of instrument engineering, while inventions can be used in the production of quartz generators for product quality control, as well as in measuring equipment. A thermostat contains a detachable case, a main board, a heating element and equipment for a tested product, a board of which is connected to the main board and the heating element by fastening elements, a Peltier heating element and a heat distributor in the form of a stepped disk made of high heat-conductivity metal are installed in the upper part of the case, a heat distribution disk is fixed on heat-insulating bushings in contact with the Peltier element located horizontally on a case wall and is equipped with a thermal sensor, which is installed in close proximity to the free surface of the heat distributor, in the lower part of the case, in accordance with the free surface of the heat distributor disk, a separator disk is installed on the equipment board, made of high heat-conductivity metal and equipped with holes, in which contact devices for tested products are placed, and power stabilizers for each product and a multi-channel frequency meter for measuring output signal frequencies of tested products are installed on the main board, while surfaces of disks of both parts of the case are tightly attracted to each other by means of a coupling bolt installed in a thermally insulated channel made at the case base, on which a connector of thermostat connection to any of docking stations is located.

EFFECT: increase in the accuracy of predicting and the speed of testing when assessing the long-term instability of the frequency of quartz resonators.
