Display unit, the result that control module is exported shows.
Particularly, described current vortex sensor is the reflective high frequency current vortex sensor.
Particularly, described digital processing element is the CS1180A/D integrated circuit.
Above-mentioned the utility model utilizes current vortex sensor can realize that the noncontact metal material measures, and measurand is not had influence, and simple in structure, highly sensitive, Hz-KHz is wide, do not receive the influence of media such as greasy dirt, has application and popularization value preferably.
Description of drawings
Fig. 1 is the structured flowchart of the utility model embodiment.
Fig. 2 is the current vortex sensor fundamental diagram.
Fig. 3 is the circuit diagram of the utility model current vortex sensor shown in Figure 1 and digital processing element.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Like Fig. 1, Fig. 2 and shown in Figure 3, the metal material analyser of the utility model comprises: current vortex sensor is used to detect magnetic flux change and the inductance value and the output of measurand; Digital processing element is used for exporting after conversion of signals with sensor output becomes effective digital signal, for example can adopt CS1180A/D integrated circuit (as shown in Figure 3); Storage unit is used for the valid data of storage standards signal; Control module, digital signal and the standard signal in the storage unit that digital processing element is exported compare the output of processing back, and control module can adopt various single-chip microcomputers or appropriate PLC or even computer etc.; Display unit, the result that control module is exported shows.
Above-mentioned current vortex sensor when dissimilar standard metal materials are measured, the magnetic flux change difference that causes and the difference of inductance value, the difference of this magnetic flux change and inductance value through digital processing after and store.The data that store, when measuring object being measured compare numerical value and the calibration value measured as calibration value again, so just can judge that measuring object is certain metal material.
Wherein, above-mentioned current vortex sensor is the reflective high frequency current vortex sensor.
