Abstract
The invention relates to a water level sensor circuit and a water level sensor. The water level sensor circuit comprises a power input end, a signal output end, a triode, a first probe and a second probe, wherein the power input end and the signal output end are connected in parallel and connected to an emitter of the triode; the first probe is connected to a base of the triode; and the second probe is connected to a collector of the triode. The water level sensor circuit and the water level sensor can monitor the residual water level in a purifier in real time, are easy and convenient to operate and can ensure oil quality.
Description
Technical field
The invention belongs to technical field of fuel filtration, relate to a kind of sensor, relate in particular to a kind of level sensor circuit and level sensor that in reconditioner, adopts.
Background technology
Meeting residuary water, colloid, pitch and impurity in industrial oil (like diesel oil, kerosene, gasoline, hydraulic oil and lubricated wet goods) production run; And in transportation, storage process, inevitably some pollution problems can appear, be easy to sneak into many such as impurity such as ashes, metal oxides; This type of oil product; When particularly fuel oil used as engine oil, because its atomizing effect is poor, burning back emission smoke intensity value was high; Cause air pollution, also can cause to a certain extent when wasting energy and damage to engine.Therefore need carry out purified treatment to these industrial oils.The various reconditioners that adopted at present all adopt closed container to carry out; Because the water through filter element filtering falls can be in the purification plant bottom deposit; When deposit of moisture to a certain amount of and cleaning in time can reduce the filter core work efficiency and damage filter core; And water can enter into and filtered in the clean oil, causes engine to damage, and also do not have to measure at present the measurement mechanism of profit position.
Summary of the invention
In order to solve the above-mentioned technical matters that exists in the background technology, the invention provides and a kind ofly can monitor residual water level in the purification plant, the easy and simple to handle and level sensor circuit and the level sensor that can guarantee the oil transportation quality in real time.
Technical scheme of the present invention is: the invention provides a kind of level sensor, its special character is: said level sensor circuit comprises power input, signal output part, triode, first probe and second probe; Insert the emitter of triode after said power input and the signal output part parallel connection; Said first probe inserts the base stage of triode; Said second probe inserts the collector of triode.
Above-mentioned level sensor circuit also comprises first filter capacitor; One end ground connection of said first filter capacitor, the other end and the common base stage that inserts triode after first probe is parallelly connected.
Above-mentioned level sensor circuit also comprises second filter capacitor; One end ground connection of said second filter capacitor, the other end and the common emitter that inserts triode after power input and signal output part are parallelly connected.
A kind of level sensor based on above-mentioned level sensor circuit, its special character is: said level sensor comprises probe support; Said level sensor circuit is arranged on probe support inside; First probe of said level sensor and second probe are parallel to be arranged on the probe support.
Advantage of the present invention is:
Level sensor provided by the present invention adopts two probes, is co-located on some isometry positions in the purification plant, when two probes are co-located in the oil, owing to the resistance between two probes is very big, almost approaches insulation, exports high level this moment; And when two probes were co-located in the water, its resistance was very little, conducting easily, and output low level, when two probes were co-located in the oil water mixture state, its output was between the high-low level.The staff judges that according to the height of level water in the position of reconditioner, in time clears up the moisture in the reconditioner.

Embodiment
Referring to Fig. 1, the invention provides a kind of level sensor circuit, this circuit comprises power input 6, signal output part 7, triode 4, first probe 1 and second probe 2; The emitter of power input 6 and signal output part 7 parallel connection back access triodes 4; First probe 1 inserts the base stage of triode 4; Second probe 2 inserts the collector of triode 4.
The level sensor circuit also comprises first filter capacitor 3 and second filter capacitor 5; One end ground connection of first filter capacitor 3, the other end and the common base stage that inserts triode 4 in first probe, 1 parallelly connected back; One end ground connection of second filter capacitor 5, the other end and the common emitter that inserts triode 4 of power input 6 and signal output part 7 parallelly connected backs.
Principle of work of the present invention is: adopt two probes; Be co-located on some isometry positions in the purification plant; When two probes are co-located in the oil,, almost approach insulation owing to the resistance between two probes is very big; Triode T by, by signal output part 7 output high level (near supply voltage 5V); And when two probes were co-located in the water, its resistance was very little, and conducting easily by signal output part 7 output low levels, is sent alerting signal, reminded the residue in staff's cleaning device; When two probes were co-located in the oil water mixture state, the signal of being exported by signal output part 7 was between the high-low level.Can measure the position of fuel-displaced, oil water mixture and water according to the variation of signal output part voltage.
Referring to Fig. 2, the present invention also provides a kind of level sensor based on foregoing circuit, and this sensor comprises probe support 8; The level sensor circuit is arranged on probe support 8 inside; First probe 1 of level sensor and second probe, 2 parallel being arranged on the probe support 8.
The present invention is applicable to the purification plant of existing various industrial oils.
