STRAIN-MEASURING TRANSDUCER Russian patent published in 2010 - IPC G01D9/00 

FIELD: physics.

SUBSTANCE: strain-measuring transducer has a tensoresistor bridge dc voltage power supply with variable polarity, a reference voltage source, a calibration signal conditioner and a system main line command decoder. The strain-measuring transducer also has a sigma-delta averaging analogue-to-digital converter which has a switch for selecting the operation mode of the converter, a device for sampling and storing the input signal, a transducer with charge compensation, a digital low-pass filter, a data register and a control register. Said measurement units are connected in a given circuit.

EFFECT: wider frequency range of measured signals, shorter time and higher measurement accuracy, simple design of the transducer.
