Abstract
The utility model relates to a liquid-level sensor, belongs to the field of electronic devices, and is generally used for automatic control. The liquid-level sensor is provided with a tank, and is characterized in that a pressure sensor is welded at the bottom of the tank and is connected with a liquid-crystal display through a circuit. The liquid-level sensor is simple to operate, and capable of accurately reflecting control signals, monitoring liquid level and preventing great economic loss even under the condition of few materials in the tank.
Description
[technical field]
The utility model relates to a kind of liquid level sensor, belongs to electron device, is generally used for automation field.
[background technology]
The general law of connected vessels that adopts was monitored liquid level and is controlled the starting material addition by liquid level gauge during modern lubricating oil or anti freezing solution were produced, and needed simultaneously the manual observation liquid level, complicated operation, and if turnout can't monitor liquid level more at least.
[utility model content]
The utility model provides a kind of liquid level sensor for addressing the above problem.The utility model is simple to operate, can accurately reflect control signal, can prevent heavy economic losses.
The technical scheme that the above-mentioned purpose that realizes the utility model adopts is as follows:
A kind of liquid level sensor has a tank body, and it is characterized in that: be welded with pressure transducer in tank base, pressure transducer has liquid crystal display by connection.
Adopt technique scheme, by pressure transducer induced liquid pressure, be converted into the liquid level data, show by liquid crystal display, do not need the manual observation liquid level, even and in the tank body in the less situation of starting material, still can accurately monitor liquid level.
[description of drawings]
Shown in Figure 1 is structural representation of the present utility model.
[embodiment]
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:
As shown in Figure 1, the utility model has a tank body (1), at tank body (1) bottom welding pressure transducer (4) is arranged, and pressure transducer (4) is connected with liquid crystal display (2) by circuit (3).Fluid pressure is answered in pressure transducer sense (4), is converted into the liquid level data, shows by liquid crystal display (2), and obtains the actual addition of liquid by computing formula.
Claims (1)
1. a liquid level sensor has a tank body (1), it is characterized in that: at tank body (1) bottom welding pressure transducer (4) is arranged, pressure transducer (4) is connected with liquid crystal display (2) by circuit (3).
