The sensor itself of intelligence flow meter also is phyletic and various, principle each different, detect the object also is multifarious, to classification the job brought certain difficulty, general sensor undertakes classified by following principle: 1, classifying method of this kind of classification by physical principle is regard classification as the basis with the physical principle of sensor. Can divide to press type of the block type, type that suppress report, inductance type, capacitance type, meet an emergency, Huo Er type... ; Method of this kind of classification is helpful for sensor major worker making the analysis of Baconian sex and research from principle and design. 2, classify by quantity be detectinged by classification be metricaled by check, can divide for physical quantity sensor, chemistry measures sensor, biomass sensor. Can divide again in of all kinds sensor for a certain number of a group of things with common features, in every gens can fractionize is a certain number of groups. 3, the working mechanism classification that presses sensor by the working mechanism classification of sensor, can divide for the structure model with content sex model two kinds big. Structure sensor is to use physics midfield law and athletic law to wait form. The law in physics is commonly give out with equation. To sensor, these equation namely the mathematical model when a lot of sensor are working. The function that characteristic of this kind of sensor is sensor and its construction material is done not have how old relation. It is with differential transformer exemple, no matter use slope not alloy or ferrite make core, still use copper cash or other lead to do winding, it is as differential transformer job. 4, press energy deliver means to classify those who press energy to deliver means classification, sensor can be divided for active sensor and passive sensor two kinds big. Active sensor is blame n changeover n. Passive sensor itself is not a transducer, n of the blame that be measured has control to the energy in sensor only or adjust action, so it must have auxiliary the sources of energy -- power source. 5, be being outputted according to sensor is imitate signal or digital signal, can divide for imitate sensor and digital sensor; According to transition reversible, can divide wait a moment for two-way sensor and one-way sensor.
