HEMP Equipamento de Medição de Pressão
The Pressure Measurement Unit, "HEMP", designed by EDIBON, allows to study pressure measurement techniques widely, since different manometers can be used to understand and compare the operation characteristics of the different devices and to study their calibration principles.
The Pressure Measurement Unit, "HEMP", enables a wide range of investigations and studies into pressure measurement techniques, using Bourdon type manometers and different U-tube manometers, to understand the operation, the characteristics of the devices, and to study the principles of calibration and to do practical exercises and experiments about it.
The "HEMP" unit mainly consists of:
- Vertical "U" type manometer (direct measurement).
- Inclined "U" manometer (direct measurement).
- Positive pressure Bourdon manometer (indiret measurement).
- Negative pressure Bourdon manometer (indiret measurement).
In addition, the unit includes a Dead Weight Calibrator, "FME10". It consists of a cylinder with a sliding precision piston fitted inside. A mass calibrated system is added to generate a certain amount of preset pressures inside the cylinder. The Bourdon manometer, whose correct operation has to be checked beforehand with the aid of the piston and masses, is connected to the cylinder through a flexible tube.
