Abstract
The utility model relates to a small-sized water-in-oil sensor which comprises a water sensor probe and a joint body, wherein the water sensor probe and the joint body are sealed. The tail of the joint body is connected with a cylindrical circuit board shell; the joint body and the circuit board shell are sealed. A circuit board with a built-in water treatment circuit is arranged in the circuit board shell; an introduction end of the circuit board is connected with a wiring end of the probe through a conducting wire. The tail of the circuit board shell is connected with a compaction bolt with a built-in eduction hole through threads; the compaction bolt and the circuit board shell are sealed. An eduction end of the circuit board is connected with a signal wire which is educed from the eduction hole. The utility model has the advantages that the volume is small; the small-sized water-in-oil sensor can make oil and water mixed liquid successfully flow through without influencing the flow speed of oil and water when oil is discharged.
Description
Technical field
The utility model is particularly related to a kind of small-sized water content in oil sensor.
Background technology
Existing water content in oil sensor is by moisture transducer probe, guard shield, discoid housing, be contained in the housing in establish the wiring board of aqueous treatment circuit, the signal wire of being drawn by housing constitutes.The problem that exists is when being used for tank unloading mouth emptying test water percentage, and discoid surface of shell retaining oil causes that oily flow velocity is slow, the emptying time is long.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, and provides that a kind of volume is little, can make the smooth and easy small-sized water content in oil sensor that flows through, do not influence the profit flow velocity of oil-water mixture during emptying.
The utility model is achieved in that it has a moisture transducer probe, fittings body, seal between said moisture transducer probe and the fittings body, its special character is to be connected with cylindric wiring board housing at the fittings body afterbody, seal between said fittings body and the wiring board housing, establish the wiring board of aqueous treatment circuit in the wiring board housing, being provided with, said wiring board leading-in end links to each other with the probe terminals by lead, at the afterbody of wiring board housing by establishing the hold-down bolt of fairlead in being threaded, seal between hold-down bolt and the wiring board housing, said wiring board exit is connected to signal wire and draws through fairlead.
According to above-mentioned small-sized water content in oil sensor, said moisture transducer probe is conical with the surface of contact of probe fittings body, to improve sealing effectiveness therebetween.
According to above-mentioned small-sized water content in oil sensor, the surface of contact of said wiring board housing and hold-down bolt is conical, to improve sealing effectiveness therebetween.
According to above-mentioned small-sized water content in oil sensor, be placed with seal gasket and pad behind hold-down bolt front end face and the wiring board between the internal orifice.
According to above-mentioned small-sized water content in oil sensor, the rear end of corresponding moisture transducer probe is provided with step in fittings body, insulating washer is housed on step and compresses by nut.
The utility model has the advantages that volume is little, can make during emptying that oil-water mixture is smooth and easy to be flow through, do not influence the profit flow velocity.
