Abstract

The invention relates to the technical field of liquid-level detecting devices and particularly discloses a non-contact type liquid-level detecting device for a non-magnetic material container. The non-contact type liquid-level detecting device comprises an inner-wall measuring device and an outer-wall measuring device, wherein the inner-wall measuring device comprises a buoy, a connecting rod and a radial magnet; the outer-wall measuring device comprises a Hall angle detector, a single chip microcomputer and an output line; the buoy is immersed in liquid in the container; one end of the connecting rod is hinged with the buoy, and the other end of the connecting end is rigidly connected with the radial magnet which is connected with a rotary shaft; the rotary shaft is fixed on the inner wall of the container; a Hall probe of the Hall angle sensor is fixed on the position of the outer wall of the container corresponding to the radial magnet; and the Hall angle sensor is connected with the single chip microcomputer by the output line. The non-contact type liquid-level detecting device disclosed by the invention has the advantages that holes in the wall of the non-magnetic material container is not needed to be drilled, and the linkage between the buoy and the senor is not needed, so that non-contact type measurement is realized and modular and accurate measurement for the liquid level is easily formed.

Description

technical field [0001] The invention relates to the technical field of liquid level detection devices, in particular to a non-contact non-magnetic material container liquid level detection device. Background technique [0002] As one of the technical methods of liquid level detection, float level detection is widely used in industrial production process, especially in process control. At present, the working principle of the buoy liquid level measuring device is: 1. The buoy and the sensor are linked. When the liquid level changes, the displacement of the buoy of the measuring device changes, and the sensor linked with the buoy generates a corresponding electrical signal output through the sensitive element; 2. The buoy and the liquid level pointer scale are used together. With the change of the liquid level, the buoy generates displacement, and the liquid level pointer connected with the buoy moves along the liquid level scale to measure and calculate the liquid volume of t...
