Fig. 2 is the utility model mainframe box internal circuit block diagram.
In figure, 1-pops one's head in rod, 2-mainframe box, 3-through the wire of insulation processing, 4-temperature sensor.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Shown in Fig. 1, Fig. 2; a kind of portable crude oil moisture tools for measurement; described probe rod 1 is high temperature resistant, corrosion-resistant, wear-resistant insulation column; overall length 18cm; effective length (must crude oil length be inserted during measurement) 8cm; outside is wound around two wires 3 through insulation processing as coil using two helicitic texture side by side, and inside is provided with temperature sensor 4, and probe rod 1 and internal temperature sensor thereof all connect the capacitance-voltage change-over circuit in mainframe host computer case 2 by wire; Main frame is comprised in described mainframe box 2; main frame connects printer, touch-screen, power supply, amplifying circuit respectively; the amplifying circuit other end connects capacitance-voltage change-over circuit; power supply is for providing ± galvanic the power supply changeover device of 15V; capacitance-voltage change-over circuit model is CAV424; host information collection, process, Presentation Function coordinate hardware to complete by the intrinsic program of single-chip microcomputer in main frame, belong to prior art, not within the utility model protection domain.
Utility model works principle: (water: 80, oil: 2 ~ 2.7), so when oil and water mix with different ratios, water percentage is higher, and the specific inductive capacity of mixing material is larger because water and oily dielectric constants are very large.Meanwhile, under the prerequisite that measuring condition is certain, the specific inductive capacity of mixing material is larger, and electric capacity is also larger, and wet oil is as fluid-mixing, and when capacitance probe is placed in crude oil, water percentage high capacitance is large, and the low electric capacity of water percentage is little.The water percentage of crude oil so just can be obtained by the electric capacity measuring crude oil.
The size of electric capacity is except main by except moisture control, and also relevant with the size of sensor, different because of the structure of probe, the expression way of formula is also different.The probe of what we adopted is two helicitic texture, the approximate formula of capacitance C is:
In formula: N: be the number of turn of coil;
ε: be the specific inductive capacity of medium between line;
R: be the center radius of coil;
R: be the linear diameter of wire;
δ: be distance between centers of tracks;
Under the condition that the center radius of the visible number of turn at coil, coil, the linear diameter of wire, distance between centers of tracks are certain, electric capacity is directly proportional to the specific inductive capacity of crude oil, and Here it is measures the theoretical foundation of crude oil water content.
Concrete, during operation, first check various cable, whether power supply is normal, under normal circumstances, open power supply, preheating prepares to measure for 5 minutes, usually first sample water-bath is heated to about 70 DEG C, then homogenizing samples is carried out, stirred sample makes bubble loss, then probe is inserted sample, start to measure, probe records crude oil electric capacity, voltage is converted to through capacitance-voltage change-over circuit, that main frame records voltage swing by amplifying circuit, thus record crude oil water content, until touch the stable temperature of screen display and water percentage registration, data measured can be printed by printer when needing, facilitate record, probe is taken out after measurement, detecting head surface is wiped clean with cotton yarn etc., prepare to measure next time.
