Control Conditions Of Float Switch

The float switch puts a hollow float in the liquid. When the liquid level changes, the float will produce the same displacement as the liquid changes. The displacement of the float can be measured by mechanical or electrical methods, and the accuracy is ± 1-2%. This liquid level switch is not suitable for high-viscosity liquids, and its output end has a switch control box for continuous output.

The float switch uses a magnet to sense the reed switch, so the measured liquid level should be free of iron filings, otherwise it will affect the action of the float switch.

The float level switch only needs to re-calibrate the water level line before we install it. It is impossible to adjust the switch itself. At this time, use a multimeter to test the switch status, and it will switch on and off with the water level near the waterline, which shows that there is no problem. Just make sure that the water level of the thermal equipment is consistent with the installation process. For example, the liquid level switch of SOR, generally there is a water level line on the wall of the cylinder. We soak the switch in the sink and sink slowly, so that the water surface gradually approaches the marking line, and when it approaches, the micro switch will be heard. sound.
