Abstract

The invention relates to a side-mounted type magnetic induction liquid level switch, which comprises an output lead, a threaded connector, a transitional part, a non-magnetic stainless steel tube, a dry reed pipe, a hollow magnetic floater and a catch, wherein, the transitional part is arranged at one side of a box body, and the threaded connector is arranged on the transitional part; one end of the non-magnetic stainless steel tube is connected with the threaded connector, and the other end of the non-magnetic stainless steel tube is provided with the catch; the dry reed pipe is arranged in the non-magnetic stainless steel tube; and the hollow magnetic floater is sleeved outside the hollow magnetic floater, and the specific gravity of the hollow magnetic floater is less than that of liquid. The switch solves technical problems that the prior liquid level switch has large volume, complicated structure, difficult connection, each leakage, and bad detection reliability, has the advantages of simple structure, small volume, low energy consumption, safety and sensitive and reliable detection, and can be widely applied to the liquid level measurement of corrosive liquid and combustible liquid such as oil and so on.

Description

technical field [0001] The invention relates to a magnetic induction liquid level switch, which can be widely used in the liquid level measurement of various corrosive liquids and flammable liquids such as oil. Background technique [0002] At present, the structure of the commonly used liquid level switch is to connect the middle and upper part of a steel wire with a flange, and the steel wire swings up and down with the connection point of the steel wire as the axis. A float is installed on the lower part of the steel wire, and a metal shrapnel is installed on the upper part. Move, the upper shrapnel also moves, a metal contact is installed in the appropriate position, can be in contact with the shrapnel, the flange is connected with the tank of the liquid to be measured, for the purpose of measurement. The liquid level switch with this structure has a large volume, a relatively complex structure, difficult flange connection, and is prone to leakage, so the detection relia...
