Description
Technical field
This utility model is related to level gauging field, and in particular to case liquid level detection device is sent out in accumulating.
Background technology
Wide variety of liquid level detection device mainly has float-ball type detection means and electric pole type detection means in the market
Two kinds, wherein float-ball type detection means is primarily present problems with：
1st, low precision.Floating-ball level switch depends on the position of ball float, as the ball float running orbit that rocks of liquid repeats
Property is poor；Low precision.
2nd, Applicable temperature is low.Megathermal float-ball type detection means is mostly water shutoff silver in stainless steel casing at present, due to
Hydrargyrum expanded by heating is easily caused detection failure；
3rd, easily wind.As float-ball type detection means afterbody is with cable, easily wind with other objects.Electric pole type is examined
Survey device and be primarily present problems with：
1st, pollution liquid.Due to there is electric current to pass through in testing liquid, the electrolyte in testing liquid can be produced in-between the electrodes
Raw electrolysis, affect the composition of testing liquid, cause testing liquid to pollute.
2nd, low precision.Electric pole type detection means detects that two resistance between electrode, liquid component determine the conductivity of liquid,
Due to the change of liquid component in actually used, two interelectrode resistance dynamic changes, and switching threshold be fixed, therefore
Low precision.
Above two detection means due to powered and be located at liquid internal, being susceptible to electric leakage causes peril, institute
All there is poor stability；Simultaneously because the impact of fouling and electrochemical corrosion, the shell of float-ball type detection means and
The electrode of electric pole type detection means is easily corroded, and service life is short.
Accumulating sends out case in actual applications, will often be related to the Level Detection of environment, and case is sent out in accumulating needs a measurement
Convenient, data display intuitively liquid level detection device.
Utility model content
This utility model aims to provide a kind of easy to detect, data display intuitively liquid level detection device, this utility model
Technical scheme be：Case liquid level detection device is sent out in accumulating, including：Fuel gauge and fuel tank, it is characterised in that：
The fuel gauge includes that display, central processing unit and input circuit, display connect central processing unit, centre
Reason device arranges analogue signal module and digital signaling module, and analogue signal module connects digital signal module by A/D converter,
Analogue signal module connects input circuit；
The top of oil-tank arranges sealing plate, and sealing plate arranges gas outlet, and sealing plate arranges perforation, and input circuit is by wearing
Cross the power line of perforation, output lead to be connected with fuel amount detector with earth lead, fuel amount detector is located at fuel pump module
Interior, fuel amount detector is attached with power line, output lead and earth lead by magnetic sensor unit, fuel amount detector bag
Include center of rotation and magnetic piece jaggy is set, center of rotation is fastened in breach, and center of rotation connects floating block by arm.
Beneficial effect：
1st, high precision.Floating block with higher recyclability, and is completely cut off with outside, is therefore had in fuel tank internal
There is very high precision.
2nd, broad application temperature range：Measurable lowest temperature, is determined by the freezing point of liquid, by selecting different magnetic piece,
Highest can be surveyed to 900 DEG C or so.
3rd, this utility model is measured to analogue signal, and digital form is intuitively shown.
