Side-mounted suspended magnetic induction liquid level switch

Abstract

The invention relates to a side-mounted suspended magnetic induction liquid level switch, wherein a liquid level switch is arranged at the position of a through hole at the side of a box body and comprises a transition part, a threaded connecting head, a stainless steel pipe, a dry reed pipe, an output lead, a horizontal shaft, a stainless steel rod, a floater and a weight. The invention solves the technical problems of large size, complicated structure, difficult connection, easy occurrence of leakage and poor detecting reliability of a traditional liquid level switch. The side-mounted suspended magnetic induction liquid level switch has the advantages of simple installation, convenient wire connection, high switch reliability, long service life, high sensitivity and low energy consumption.

Description

technical field

[0001] The invention relates to a magnetic induction liquid level switch, in particular to a magnetic induction liquid level switch applicable to liquid level measurement of various corrosive liquids and combustible liquids. Background technique

[0002] At present, the structure of the commonly used liquid level switch is to install a float on the lower part of a steel wire, connect the middle and upper part with a flange, and install a metal shrapnel on the upper part. Moving up and down, the upper shrapnel also moves accordingly, and a metal contact that can be in contact with the shrapnel is installed at an appropriate position, and the flange is connected with the tank of the measured liquid to achieve the purpose of measurement. The liquid level switch with this structure has a large volume, a relatively complicated structure, difficult flange connection, easy leakage, and poor detection reliability.
