С целью повышени  точности измерени  в предлагаемом устройстве в цепь питани  моста включен резистор, зажимы которого соединены с входом делител  напр жени .In order to improve the measurement accuracy in the proposed device, a resistor is connected to the bridge power supply circuit, the terminals of which are connected to the input of a voltage divider.

На чертеже изображено предлагаемое устройство .The drawing shows the proposed device.

Устройство дл  измерени  сигналов с параметрических преобразователей, соединенных по схеме моста 1, содержит коммутатор 2, делитель 3 напр жени , блок 4 управлени , источник 5 питани  моста, нуль-орган 6, один из входов которого соединен через коммутатор 2 с измерительной диагональю моста, второй вход - с выходом делител  3 напр жени , а выход-с входом блока 4 управлени , выход которого св зан с делителем 3 напр жени . Устройство включает также резистор 7, включенный в цепь питани  моста 1A device for measuring signals from parametric converters connected according to bridge 1 comprises a switch 2, a voltage divider 3, a control unit 4, a bridge power supply 5, a null organ 6, one of the inputs of which is connected through a switch 2 with a bridge diagonal measurement, the second input is with the output of the voltage divider 3, and the output is with the input of the control unit 4, the output of which is connected with the voltage divider 3. The device also includes a resistor 7 connected to the power supply circuit of bridge 1

и соединенный .зажимами с входом делител  3 напр жени .and connected by clips to the input of the divider 3 voltage.

Напр жение от источника 5 питани  подаетс  на мост через резистор 7, падение напр жени  на котором поступает на вход делител  3 напр жени .The voltage from the power source 5 is supplied to the bridge through a resistor 7, the voltage drop on which is fed to the input of the voltage divider 3.

При наличии деформации выходное напр жение пропорционально абсолютному изменению сопротивлени  тензорезисторов моста 1. Измерение абсолютных приращений сопротивлений тензорезисторов необходимо при использовании полупроводниковых тензорезисторов .In the presence of deformation, the output voltage is proportional to the absolute change in resistance of the resistance strain gages of bridge 1. Measurement of the absolute increments of resistance of the resistance strain gages is necessary when using semiconductor strain gages.

Входное напр жение делител  3 напр жени  пропорционально току питани  моста, поэтому в момент компенсации, когда выходное напр жение моста равно выходному напр жению делител  3 напр жени , абсолютное изменение сопротивлени  пропорционально величине резистора 7 и коэффициенту делени  делител  3 напр жени .The input voltage of the divider 3 voltage is proportional to the current supply of the bridge, therefore at the time of compensation, when the output voltage of the bridge is equal to the output voltage of the voltage divider 3, the absolute change in resistance is proportional to the value of the voltage divider 3.

Таким образом, предлагаемое устройство позвол ет измер ть абсолютные приращени  сопротив.:тений тензорезисторов моста, исключа  вли ние соединительных линий и коммутирующих элементов на точность измерени .Thus, the proposed device makes it possible to measure the absolute increments of the resistance: the tenium strain gauges of the bridge, eliminating the influence of connecting lines and switching elements on the measurement accuracy.
