DEVICE FOR MEASURING THE STRAIN OF SOLIDS Russian patent published in 2017 - IPC G01B7/16 

FIELD: measurement equipment.

SUBSTANCE: device comprises tensor-measuring strain gauge blocks, power supply, and analog-digital converter, an electronic hub repeater unit. Each tensor measuring unit further comprises a transceiver, a transistor switch, a microprocessor and a temperature sensor. Strain gauges connected to the transistor and with the key input of the analog-digital converter whose output is connected to an input of a microprocessor, whose output is connected with the transceiver. The temperature sensor is connected to the microprocessor. Tensor measuring blocks set apart by a distance providing overlapping action blocks strain zone. Repeater unit comprises a transmitter-receiver module, radio, transistor switch, switching power supply, a microprocessor and a temperature sensor. Yield transceiver module connected to the input of the microprocessor, whose output is connected to a wireless modem. Another microprocessor output is connected to a transistor switch having an input connected to a source of direct current, and the output is connected to a wireless modem. The output switching power supply is connected to the microprocessor. Output radio channel for a radio channel connected to the electronic hub.

EFFECT: increased sensitivity and measurement accuracy, increase operational reliability and efficiency of measurement data including at low temperatures.
