BENCH FOR PRESSURE SENSORS VERIFICATION AND CALIBRATION Russian patent published in 2016 - IPC G01L27/00 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measurement equipment, in particular, to devices for verification and calibration of pressure sensors. A bench for verification and calibration of pressure sensors comprises a header to connect reference and calibrated pressure sensors, a device for pressure pulling, connected by a pneumatic manifold with the header, and a meter-calibrator of pressure, comprising a computing-controlling device, an indication unit and a printing unit. The header additionally comprises stop valves installed upstream each pressure sensor. The pressure meter-calibrator additionally comprises a unit of high-precision conversion of unified current output signals into a universal data transmission interface and a unit of digital signal conversion into a universal data transmission interface, connected to the computing-controlling device. Calibrated pressure sensors are connected to the unit of high-precision conversion of unified current output signals into the universal data transmission interface, and the reference sensor is connected to the unit of digital signal conversion into the universal data transmission interface.

EFFECT: expansion of technical capabilities, design simplicity, convenience of operation.
