Specific embodiment
With reference to embodiment and attached drawing, the utility model is described in further detail, but the reality of the utility model
The mode of applying is not limited only to this.
The utility model is intended to provide a kind of spool height detecting device, which is characterized in that as shown in Figure 1, it is included directly
Galvanic electricity source 1 and linear displacement transducer 4, the DC power supply 1 are configured as 24V constant voltage DC electric currents source, the DC power supply 1
Output terminal input terminals that signal amplifier 2 is connected to by switch 9, the output terminal of the DC power supply 1 also passes through switch 9 and connects
The input terminal of power lights 3 is connected to, the linear displacement transducer 4 includes slide rheostat 5 and slide plate 6, the slide rheostat 5
One end connect with the voltage output end of signal amplifier 2, the other end of the slide rheostat 5 ground connection, the slide plate 6 with it is sliding
The 5 movable end connection of dynamic rheostat, the slide rheostat 5 are also connected to signal amplifier 2, the slip variable resistance by slide plate 6
5 both ends of device connect steady-state DC voltage, the low current allowed to flow through micromicroampere, between 5 beginning of the slide plate 6 and slide rheostat
Voltage it is directly proportional to the length that slide plate 6 moves, the output terminal of the signal amplifier 2 be respectively connected to qualified indicator light 7 with
And the input terminal of unqualified indicator light 8, the output terminal of the power lights 3, qualified indicator light 7 and unqualified indicator light 8 connect
Ground.
When it is implemented, the filling spool 10 for needing to detect is touched to the slide plate 6 of linear displacement transducer 4, due to straight
For linear movement pick-up 4 as a slide rheostat, slip of the slide plate 6 on slide rheostat 5 causes linear displacement transducer 4
Output voltage change, voltage is converted to digital signal by signal amplifier 2, pass through signal amplifier 2 setting setting
The bound of number judges the qualification/unqualified state for filling spool 10, passes through qualified indicator light 7 and unqualified instruction
The current height condition of the display filling spool 10 of lamp 8.
The above content is combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that the utility model specific implementation is confined to these above-mentioned explanations.For the common skill of the utility model technical field
For art personnel, without departing from the concept of the premise utility, several simple deduction or replace can also be made, all should
It is considered as belonging to the scope of protection of the utility model.
