The intensity variation timing and change frequency that receive and the direction of rotation for calculating pointer (102) and pointer (102) rotation when institute
The quantity of the narrow slit (103) of process, so that pointer (102) position indicated at present be calculated.Data processing system simultaneously
Data exchange interface with host computer is provided, pointer (102) position indicated at present is transferred in a manner of data communication
Host computer, for reading and recording.Setting reads window (108) to realize artificial reading and electronics on pointer (102) simultaneously
Read into ratio, reduce mistake occur a possibility that.
Compared with prior art, the present invention its remarkable advantage are as follows:
(1) present invention combines the characteristics of mechanical dial gauge, devise it is a kind of can electronical reading percentage list index and its dial plate,
It can be under the premise of realizing existing mechanical dial gauge advantage, while realizing the full automation of dial gauge reading process.
Labour expenses can not only be saved with round-the-clock running, also can be reduced because of artificial reading and record bring data error or mistake
Accidentally；
(2) present invention breaches the design form of existing digital display centimeter on the market, from dial plate, using dial plate as hundred
Divide the critical component of meter reading, reduces dependence of the digital display centimeter to measuring staff machining accuracy, improve measurement accuracy and measured
Data stability in journey；
(3) present invention can replace original dial gauge normal clock face, easily realize the electronic and automatic of percentage meter reading
Change, still remain the function of visible reading at the same time, user can mode reading numerical values by visual observation, check dial gauge
The accuracy of electronical reading, a possibility that reducing dial gauge electronical reading error in data, especially suitable for some for professional work
The dial gauge of journey customization, which is realized, electronic to be read.
