This unit has been designed to study pressure measuring techniques and the modes of calibration of the relevant sensors. Using a deadweight tester will enable to generate pre-fixed pressures and to calibrate a Bourdon gauge and an electronic pressure sensor. The deadweight tester consists of a piston that can house a set of weights generating pressures up to 2 bars. The pressure gauge is a typical industrial Bourdon gauge, whereas the sensor is a typical industrial pressure transmitter of piezo resistive type.
