PRESSURE MEASUREMENT DEVICE Russian patent published in 2013 - IPC G01L9/04 

FIELD: measuring equipment.

SUBSTANCE: device comprises a strain gauge bridge which input diagonal is connected to its power source, a differential amplifier which input is connected to an output diagonal of the bridge, and an output - to the input of analog-to-digital converter, a microprocessor, a read-only memory, a digital temperature sensor, a temperature corrector, an identifier, an inverter, and an adder. The device additionally comprises three-component digital accelerometer, the position corrector and the driver of digital interface of data transfer. And the output of the three-component digital accelerometer is connected to the first input of the position corrector, the second input of which is connected to the sixth output of the microprocessor, the output of position corrector is connected to the fourth adder input, and the input of the driver of digital interface of data transfer is connected to the eighth output of the microprocessor, the third input of which is connected to the output of the driver of digital interface of data transfer.

EFFECT: increased accuracy of measurement and improvement of operational characteristics.
