Description
Известные в машиностроении измерительные средства дл контрол размеров не компенсируют и не учитывают изменеНи размеров издели , вызванного отклонением его темнературы от нормальной.Measurement tools known in mechanical engineering do not compensate for dimensions and do not take into account changes in product dimensions caused by a deviation of its temperature from the normal one.
С номондью предлагаемого измерительного устройства устран ютс непроизводительные затраты времени на приведение темнературы нагретого в ироцессе обработки издели к темиературе измерительного средства.With the performance of the proposed measuring device, the non-productive time spent on converting the temperature of the processing of the product heated in the process to the measurement of the measuring means is eliminated.
Это достигаетс тем, что в цепь отсчетного прибора нарал.тельно или иос.тедопательно ему вводитс компенеируюнщй ток, величина и знак которого пропорциональны тепловым деформаци м издели . В качестве комиенсьрующего э.темента нримеи етс термистор, контактирующий с изделием и включенный в мостиковую схему, ток разбаланса которой иснользуетс в качестве компенсационного тока.This is achieved by the fact that a compensating current is introduced into the circuit of the reading device, either electrically or by Jos. The magnitude and sign of which is proportional to the thermal deformations of the product. A thermistor in contact with the product and included in a bridge circuit, the unbalance current of which is used as a compensation current, is used as a commencement of this temperature.

The voltage of the bridge disbalancing through the phase-sensitive system made up by rectifier 7 and outliers 8 and 9 is supplied on the meter
