Abstract
The utility model relates to an external liquid level sensor, particularly a liquid level sensor used for controlling a liquid level. The external liquid level sensor is provided with a test tube (1) which is made of nonmagnetic conductive materials, and the test tube (1) is provided with a tube joint (2) communicated with a liquid outlet tube of a tested container. A magnetic induction element (7) is attached to the external wall of the test tube (1), which corresponds to the upper limit of the liquid level and the lower limit of the liquid level, magnetic floaters (3) are movably matched and arranged in the test tube (1). A structure is arranged between the external wall of the test tube (1) and the magnetic induction element (7) and can fix the magnetic induction element (7) in the positions with different heights. The external liquid level sensor has the characteristic of convenient installation, repair and orientation.
Description
Technical field: the utility model relates to a kind of external liquid level sensor, especially for the liquid level sensor of position formula liquid level control.
Background technology: existing position formula liquid level sensor is made up of magnetic float and a tubulose detector bar usually, corresponding bound liquid level place is provided with tongue tube respectively in the detector bar inner chamber, detector bar is fixed in the container intracavity and is inserted in the liquid medium, and magnetic float is made annular and is enclosed within on the detector bar and fluctuates with liquid level.The liquid level sensor of this form is because its detector bar also is to place container and be inserted into liquid medium, and therefore directly perceived, maintenance is located inconvenient.
Summary of the invention: the purpose of this utility model is to locate liquid level sensor easily for the deficiency that overcomes existing liquid level sensor provides a kind of directly perceived, maintenance.
The external liquid level sensor is provided with the testing tube that a non-magnet material is made, described testing tube is provided with the pipe adapter that is communicated with the tested container drain pipe, described magnetic induction part is sticked on corresponding upper limit liquid level of testing tube outer wall and bottom limit level position, magnetic float places testing tube movingly, and being provided with between testing tube outer wall and the magnetic induction part can be as required with the structure of magnetic induction part in the differing heights stationkeeping.
Further setting of the present utility model is evenly arranged along the axially on the testing tube outer tube wall to be provided with some blind holes, magnetic induction part is contained in the plastic casing, the plastic casing outside surface is provided with a boss that matches with blind hole, and the plastic casing that tongue tube is housed is inserted in the corresponding blind hole on demand with the fixing structure that constitutes stationkeeping of plastic casing.
Adopt the position formula liquid level sensor of said structure, because testing tube is arranged on the joint that is communicated with drain pipe, the testing tube of work is communicated with the tested container drain pipe, therefore the liquid level in the testing tube is identical with liquid level in the tested container, the magnetic induction part that is sticked on outer wall can measure the liquid level true altitude, and because magnetic induction part is to be sticked on the pipe outer wall, so the installation, maintenance location is very convenient.
The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment.
Description of drawings:
Accompanying drawing 1 is the utility model embodiment structure cut-away view;
Accompanying drawing 2 is the local enlarged diagram of Fig. 1;
Accompanying drawing 3 is the local enlarged diagram of Figure 1A-A.
Specific embodiment: as shown in Figure 1, testing tube 1 is a cylinder tube shape, upper end closed, the lower end is provided with the pipe adapter 2 adaptive with the tested container liquid outlet, magnetic float 3 places pipe movingly, evenly arranged along the axially on testing tube 1 outer tube wall be provided with some blind holes 4, magnetic induction part 7 is selected tongue tube for use and is contained in the plastic casing 5, plastic casing 5 outside surfaces are provided with a boss 6 that matches with blind hole 4, testing tube 1 is vertically connected on the drain pipe during use, the plastic casing 5 that tongue tube is housed is inserted in the corresponding blind hole 4 on demand fixes plastic casing 5, as shown in Figure 1.
