TMCP Оборудование для измерения и калибровки давления

The Pressure Measurement and Calibration Unit, "TMCP", has been designed to study the concept of pressure and the different methods and techniques used to measure this variable.

The dead-weight calibrator consists of a cylinder in which interior a precision piston is fitted and slid. Different weights are added to generate inside the cylinder a certain amount of preset pressures.

The Bourdon manometer and the pressure sensor, which must be checked and calibrated, are connected to the cylinder through a flexible tube. Any possible leakage outside the piston is directed through the flexible tube towards a vessel, to which a check valve is fitted to prevent pressure drop in the manometer due to that leakage.

The Bourdon manometer includes a scale calibrated in degrees of rotation, apart from the usual pressure scale.

The pressure sensor generates an output voltage proportional to the applied pressure.

An electronic console with two digital displays that show the output of the pressure sensor (in Volts) and the conditioned reading in two engineering units. Besides the corresponding signals are sent to an I/O port for their acquisition via software in a computer (PC).

Software used to acquire data and to obtain the calibration curve (with slope and ordinate in the origin) both in function of the angular displacement of the needle and in function of the output voltage of the sensor.
