Abstract
The utility model relates to an alarm sensor for controlling the height of liquid level, which is composed of a guide pipe without magnet conductivity and a floater, wherein the floater is movably sheathed on the guide pipe without magnet conductivity, a permanent magnet is arranged in the floater, at least one magnetic sensitive switch element is correspondingly arranged in the guide pipe without magnet conductivity, and the switch element is led out and connected with a sound, light and electric alarm device by a conducting wire. The utility model has the advantages of simple and novel structure, low cost, long service life, high positioning accuracy and security and can be applied to liquid level control under any condition.
Description
The utility model relates to a kind of sensor, particularly a kind of alarm sensor that is used to control the liquid level height.
Existing liquid level sensor has ultrasonic sensor, has the float-ball type sensor of mercury cut-off, and capacitance level transducer etc., the ultrasonic sensor precision is higher, but it costs an arm and a leg, debugging is complicated, and the height that is used for liquid level is measured more, is not suitable as the liquid level warning sensor.Though mercury cut-off sensor cost is lower, the height with liquid level when it uses rotates up and down, and it connects the lead frangibility, and serviceable life is short, and it is unsuitable for using in the stronger liquid of inflammable and explosive corrosivity.Capacitance type sensor also exist debug difficulties, cost too high, problem such as be not suitable in the liquid inflammable and explosive, that corrosivity is stronger, using.In addition, ultrasound wave and capacitance type sensor are the liquid level sensor of continuous quantity, are not suitable as the sensor that liquid level is reported to the police automatically.
The purpose of this utility model is exactly in order to address the above problem, and a kind of liquid level bearing accuracy height is provided, and cost is low, long service life, and the switching value liquid level automatic alarm sensor that can use in the liquid inflammable and explosive, that corrosivity is stronger.
The technical solution of the utility model:
A kind of switching value liquid level automatic alarm sensor, it is characterized in that it is made up of non-magnetic conduction conduit 2 and float 4, float 4 movable sets are on non-magnetic conduction conduit 2, be provided with permanent magnet 3 in it, correspondingly be provided with a magnetosensitive on-off element 5 in non-magnetic conduction conduit 2 at least, it draws access sound, light, electric alarm device 7 by lead 1.
The utility model novel structure, easy for installation, with low cost, it is reliable to report to the police, long service life, not only can be used in the liquid of light water or industrial chemicals and report to the police automatically as liquid level, also can be at gasoline, diesel oil, use in the lubricated wet goods flammable and combustible liquids and in the stronger soda acid electroplate liquid of corrosivity, its positioning control can be provided with the control automatically of multi-level point as required, the bearing accuracy height, security is good, applied range, be suitable at water supply installation, the liquid level control and the automobile of chemical industry, aspects such as the oil level control of motorcycle are used, and market outlook are very wide.
Fig. 1 is a user mode synoptic diagram of the present utility model;
Fig. 2 is a structural representation of the present utility model.
As Fig. 1,2, when the utility model uses, non-magnetic conduction conduit 2 and float 4 thereof are inserted in the liquid level that will control, the length of non-magnetic conduction conduit 2 is determined according to the height of liquid level container, and should be with it and liquid level vertical fixing, float 4 just fluctuates on non-magnetic conduction conduit 2 with the height of liquid level like this, permanent magnet 3 in the float 4 is preferably annular, it is embedded in the float 4, they are whole a connection, are provided with only end socket 6 in the lower end of non-magnetic conduction conduit 2, and it is sealed the end opening of non-magnetic conduction conduit 2 on the one hand, prevent that liquid from entering, it is used for preventing that float 4 breaks away from non-magnetic conduction conduit 2 on the other hand.The most handy epoxy resin envelope is full in the non-magnetic conduction conduit 2, and the magnetosensitive on-off elements 5 in the non-like this magnetic conduction conduit 2 just are closed parcel and fix, so be suitable for using in inflammable and explosive and liquid that corrosivity is stronger.Magnetosensitive on-off element 5 can adopt tongue tube, also can adopt the Hall switch element, its position in non-magnetic conduction conduit 2 can highly be provided with according to the location, if need carry out the control of multiple spot liquid level, during as the situation of full scale position, lower limit and 1/2 liquid level of liquid container or the like, only need to set gradually two or more magnetosensitive on-off elements 5 in non-magnetic conduction conduit 2 and get final product, they are drawn by lead 1 separately and insert warning device 7.Like this, when liquid level rises or descend, float 4 fluctuates along non-magnetic conduction conduit 2 thereupon, when the magneticaction of permanent magnet in it 3 arrives the magnetosensitive on-off element 5 of relevant position in the non-magnetic conduction conduit 2, magnetosensitive on-off element 5 is finished the automatic warning and the control of liquid level with regard to output switching signal connection sound, light, electric alarm device 7.
