State and inductance type transducer is provided with the montant of the first mounting bracket, the second mounting bracket is vertically installed with the card of the rotating disk, and
Sensor is provided with the montant of second mounting bracket, four groups of structure identical through holes are uniformly provided with the rotating disk, the rotating disk
Outer circumferential walls are also uniformly provided with copper foil paper at equal intervals.
Preferably, the bottom of the variable-frequency motor is fixed in mounting seat by mounting bracket.
Preferably, the sensor is photoelectric sensor or capacitance type sensor.
Preferably, the rotating disk is integrally formed using nylon plastic(s).
Compared with prior art, the beneficial effects of the utility model are：The utility model is used by Frequency Converter Control frequency conversion
Motor driven round turntable senses by sensor, while sensor is connected on frequency meter and detects pulse frequency, to realize sensing
The detection of device response frequency, the response frequency of multiple sensors can be detected simultaneously, simple to operate, practical value is strong.
