The magnetic flux passing through a coil of the magnet monitoring head is changed when the magnet monitoring head induces ferromagnetic substances, the pulse output is generated, the oscillator is started for beginning the oscillation after boosting pressure through the output transformer, and the monitoring indicating lamp is triggered for giving out prompting lamp signals.
Description
Affiliated technical field
The utility model relates to a kind of sniffer, especially the metal residual monitoring device.
Background technology
A lot of nonmetallic materials for example timber, plastic housing have the secondary value, under a lot of situations, the metal fixture that left behind in the manufacturing process are arranged in these materials, and the processing of material is caused a lot of troubles.Kish thing depth of burial in the material is not dark, uses special-purpose deep layer metal detector to cost an arm and a leg, and cost is too high, and is unrealistic.
Summary of the invention
Cost an arm and a leg in order to overcome special-purpose deep layer metal detector, the deficiency that cost is too high, the utility model provides a kind of metal residual monitoring device, not only can detect the degree of depth at 2cm with interior kish, and simple in structure, easy to make, with low cost.
The technical scheme that its technical matters that solves the utility model adopts is: the metal residual monitoring device, comprise magnet monitor head, output transformer, oscillator, monitoring pilot lamp, power supply, it is characterized in that: magnet monitor head, output transformer, oscillator, monitoring pilot lamp connect successively, and power supply is connected with magnet monitor head, output transformer, oscillator, monitoring pilot lamp respectively.The magnetic flux of crossing magnet monitor head coil when the magnet monitor head is sensed ferromagnetic material changes, and produces pulse output, by starting the oscillator starting oscillation after the output transformer supercharging, triggers the monitoring pilot lamp and sends the warning light signal.
The beneficial effects of the utility model are at the not dark characteristics of kish depth of burial in the nonmetallic materials, to make succinct, easy to use, the power saving, with low cost of circuit.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a theory diagram of the present utility model; Fig. 2 is an electric structural drawing of the present utility model.
Among the figure, 1. magnet monitor head, 2. output transformer, 3. oscillator, 4. monitoring pilot lamp, 5. power supply.
Embodiment
In Fig. 1, the metal residual monitoring device, comprise magnet monitor head 1, output transformer 2, oscillator 3, monitoring pilot lamp 4, power supply 5, it is characterized in that: magnet monitor head 1, output transformer 2, oscillator 3, monitoring pilot lamp 4 connect successively, and power supply 5 is connected 4 with magnet monitor head 1, output transformer 2, oscillator 3, monitoring pilot lamp respectively.When magnet monitor head 1 was sensed ferromagnetic material, the magnetic flux that passes magnet monitor head 1 changed, and produced pulse output, by starting oscillator 3 starting oscillations after output transformer 2 superchargings, triggered monitoring pilot lamp 4 and sent the warning light signal.
In Fig. 2, for preventing to disturb, whole probe wraps up with sheet iron.F1 and F2 constitute the secondary phase inverter, and F1 input end current potential is determined by the voltage divider that R1, W, R2 constitute.The W midpoint potential is a little less than the threshold voltage (2.8V) of F1.The F1 output terminal is a high level at ordinary times, and the F2 output terminal is a low level.F3 and F4, C2, R4 constitute audio frequency oscillator, and the input end of F3 links to each other with the output terminal of F2 through diode D as control end.Control end (being No. 9 pin of CD4012) is a low level at ordinary times.When ferromagnetic material is mobile between the probe magnetic pole, the magnetic flux that passes coil changes, therefore just there is an electric pulse output at the coil two ends, F1 is with regard to output low level during greater than 0.3V when amplitude, and the F2 output amplitude is near the positive pulse of 9V, after diode D rectification to capacitor C 1 charging, approximately behind 200 μ s, No. 9 pin voltage just can rise to about 9V, so the oscillator starting oscillation triggers monitoring pilot lamp 4 and sends the warning light signal.
