Embodiment
Synoptic diagram 1 shows this patent, promptly liquid sensor a kind of form.In this form, two conductors 800 insert in the nonconducting pipeline 804 as two electrodes.These two electrodes are connected a power supply and metering circuit by electric wire 802.When this segment pipe did not have liquid 810 to exist, the resistance between two electrodes was infinitely great, promptly opens circuit.When having liquid 810 existence and this liquid 810 that certain electric conductivity is arranged between these two electrodes, can judge by the resistance variations between the potential electrode whether liquid is present between these two electrodes.When two electrodes lean on enough closely, can produce capacity effect.Can measure some physical and chemical performance of this liquid by dielectric constant between the potential electrode, such as concentration.In some applications, flow to somewhere, then a series of a plurality of probes (electrode) need be installed on this pipeline such as need on a very long pipeline, surveying liquid.
Synoptic diagram 2 shows the another kind of form of this patents, and this form is applicable to the good pipeline of electric conductivity 804, at this moment, needs insulator 820 between electrode 800 and pipeline 804 both are separated.
The model of a metering circuit of demonstration is used for the resistance between the potential electrode 800 in the synoptic diagram 3, needs this moment an electric bridge to realize.In this model, need a resistance 830 to form wheatstone bridge, a controllable electric power 832 and a voltmeter 836.Press circuit shown in the figure, when not having liquid 810 to exist between the electrode, circuit disconnects, and voltmeter 836 measures no-voltage.When having liquid 810 to exist between the electrode, closing of circuit, voltmeter 836 measure a determined magnitude of voltage of ratio by resistance between the electrode 800 and resistance 830.Same similarly circuit also can be used for the dielectric properties between the potential electrode and calculate concentration or other physical and chemical performances of liquid between the electrode with this.
In above application, one crucial also is that the core main points of this patent are that to give electrode 800 power supplies are instantaneous (or opposite polarity pulses) interrupted or alternation to power supply 836, rather than continuously lasting DC current or voltage, moment in electrode 800 energising obtains reading, i.e. power supply with obtain that reading need be carried out synchronously or carry out with certain mistiming.Lasting power supply not only can cause excess liq to decompose, and also can make this method lose efficacy owing to battery or capacity effect.Show through experiment, adopt this way to survey the existence or the concentration of liquid, because battery or electric capacity (electricity is situated between) effect needs the interval of longer a period of time just can obtain next reading after obtaining a reading.When certain section time continuous coverage is read, then will adopt alternating source if desired, promptly each measures the power supply that needs an employing and a last measurement opposite polarity.No matter be continuous coverage or interrupted the measurement, need shorten total conduction time as far as possible to avoid excess liq to decompose.Through experimental results show that, under the situation of enough lacking conduction time, the decomposition of liquid, battery and capacity effect are all very faint, and this class working sensor is very good, produce a desired effect and do not produce any harmful effect for the system of liquid and carrying, conveying liquid.
Described herein only is a kind of form of the present invention.And this invention has comprised multiple different version.Each detail can have unlimited multiple different form, combination or arrangement, and this paper does not give unnecessary details.Any to change of the present invention or in different ways, the combination of method and arrangement, its result also still belongs within this invention scope.
