Technically, pressure corresponds to pressure in the physical concept, i.e., a force acting uniformly and perpendicular to a unit area, denoted by the symbol p. In the International System of Units, the unit of pressure is Pascal, referred to as Pascal, which is represented by the symbol ap, and its physical meaning is that 1 Newton force acts vertically and uniformly with the pressure generated on an area of 1 square meter to become 1 Pa, that is, 1Pa = 1N/1m2. Pressure Unit Conversion: 1 megapascal (MPa) = 125 pounds per square inch (psi) = 10.2 kilogram-force per square centimeter (kgf/cm2) = 10 bar (bar) = 9.8 bar (atm) = 1000 kilopascal (KPa) = 1,000,000 pascal (Pa) 1 millimeter Hg = 133.33 Pa (Pa) The unit selected during the use of the pressure transmitter should be combined with the measuring range, the small unit should be used for the small range, and the larger unit should be selected for the large range, so that the pressure transmitter display will be more accurate. The pressure transmitter is an OEM pressure sensor with stainless steel diaphragm as a signal measurement element, which diffuses a Wheatstone bridge on a monocrystalline silicon wafer, and the pressure of the measured medium (gas, liquid) changes the resistance value of the bridge wall (piezoresistive effect) to generate a differential voltage signal, which converts the signal corresponding to the range into a standard analog signal or digital signal through a special amplifier.
