PRESSURE TRANSDUCER Russian patent published in 2014 - IPC G01L9/04 

FIELD: instrumentation.

SUBSTANCE: outputs of stabilised feed of sensory bridge are connected with ADC and sensory bridge inputs while sensory bridge outputs are connected with normalising amplifier. Adder output is connected with normalising amplifier input. Amplifier output is connected with DAC₁ input. Output of the latter is connected with input of inertia-free compensator of the main error while its output is connected with supply and reference voltage output signal shaper input. One output of supply and reference voltage output signal shaper is connected with sensory bridge stabilised voltage feed source while it second output is connected with DAC₂ and ADC second input while third output of said shaper is connected to adder second input. ADC output is connected with the input of microcontroller its outputs being connected with second inputs of DAC₁ and DAC₂.

EFFECT: decreased temperature error, accelerated response.
