Liquid level alarm limit switch float switch gauge fuel liquid level sensor switch Measuring tools water tank instruments

The LS02 liquid level control switch is composed of a reed switch and a circuit module, with a compact structure, strong and durable. According to the purpose, it can be divided into LS021 type ordinary liquid level control switch, LS022 type with retention (memory) type liquid level control switch and LS023 type high temperature with retention (memory) type control switch.
The liquid level control switch is fixed on the outside of the LS021 or LS022 magnetic float level gauge in a bundled form, so that it is in the same magnetic field system of the liquid level gauge. When the magnetic float moves up and down with the liquid level, it corresponds to the dry position of the liquid level. The reed pipe is attracted by the magnetic field in the float, and the changing signal is converted into a passive switch signal output through the conversion module. If it is LS022 or LS023, it can hold the lead signal until the return induction signal arrives. So it can be released. It is convenient to use with various instruments to achieve the purpose of control and alarm.
