2. 2. Information Pressure measurement engineering Different pressure types Absolute pressure (Pabs) Atmospheric pressure difference, The pressure which applies to the positive pressure Atmospheric pressure Relative vacuum vacuum in the universe (zero pressure) Atmospheric pressure difference (pe) is is known as absolute pressure. Measured the difference between an absolute Measured Absolute pressure has “abs” as its pressure pressure (pabs) and the respective pressure index. atmospheric pressure (pe = pabs - pamb). This is generally referred to as positive pressure. Pressure sensitive element Pressure sensitive element Differential pressure, pressure difference Atmospheric air pressure (Pamb) (∆p) This is the most important pressure for life on earth. Atmospheric pressure is The difference between two pressures created by the weight of the atmosphere surrounding the earth. The atmosphere p1 and p2 is known as pressure Measured Measured reaches a height of up to approx. 500 km. Pressure decreases constantly up to this pressure 1 pressure 2 difference (∆p= p1-p2). If the difference height (absolute pressure Pabs = zero). Atmospheric air pressure is also influenced between two pressures is a variable, by fluctuations in the weather. The average Pamb at sea level is 1013.25 this is referred to as differential pressure Hectopascal (hPa) or millibar (mbar/ normal pressure in accordance with DIN 1343). (p1,2). Typically this value can fluctuate by ±5 % if there are low or high pressure weather areas. Pressure sensitive element Measuring principle When designing pressure meters, the principle of the effect of pressure on a defined area is almost always used. This is then Force (F) Pressure (p) = retraced to a measurement of force. Area (A) The following formula applies: Pressure meters Advantages: Electrical pressure meters measuring meters have an accuracy of Types of p ressure meters ±0.05 % of the full-scale value. In the Liquid pressure meters Electric pressure sensors There is a displacement of 1-3 mm in case of mechanical manometers, such – U-tube manometer and pressure meters elastic pressure meters. accuracies cannot be read on account – Inclined tube manometer – Sensor principles with strain meters The deformation in electrical pressure of the parallax error and mechanical – Multi-liquid manometer – Sensor principles with path sensors is only a few µm. Due to this performance of the springs. Electrical – Float manometer measurement very low mechanical deformation, precision meters with LCD display often – Compression meter electrical pressure meters / sensors have a resolution in the thousandth Pressure balances with sealing liquid – Ionisation pressure meter have an excellent dynamic performance range of 0.001. – Friction meter and low material stress resulting in high Piston pressure meters endurance levels and long-term stability. – Piston pressure meters with spring- Electrical pressure meters can also be loaded piston manufactured in very small sizes. – Piston pressure scales An additional advantage is the easy-to- Elastic pressure meters read display. Considering today’s technology standards, accurate pressure measurement is becoming more and more important.
