Pressure-resistant explosion-proof automatic control device float switch series

Pressure-resistant explosion-proof automatic control device float switch series

Automatic control and alarm switches for liquid levels in drainage tanks, oil tanks, etc. The position of the rod can be moved to the right side for water supply and to the left side for drainage, making it easy to handle!

A "float switch" is a mechanism widely used for automatic control and alarm of liquid levels in water supply and drainage tanks, as well as oil tanks, by capturing the movement of a float that floats on the liquid surface and follows fluctuations in the liquid level. The same device is used for both water supply and drainage, making it easy to handle by moving the rod position to the right side for water supply and to the left side for drainage. The center of the float has a hole for the rod to pass through, allowing the float to be mounted on the rod. Limiters for both high and low limits can be installed at any position on the rod to create changes in the liquid level. The high liquid level operates the lever through the buoyancy of the float, while the low liquid level operates the lever through the weight of the float, turning the contacts built into the housing ON and OFF. 【Features】 ■ Easy to handle ■ Operates the lever through the buoyancy and weight of the float ■ Explosion-proof options available *For more details, please download the PDF or contact us.

Float switch

Float switch

Float switch

**Overview** This float switch offsets the weight of the guide pipe with a compression spring, utilizing the buoyancy of the float to push up and the weight of the float to push down. It detects the position of the float, which follows the liquid level, using a micro switch mechanism mounted on a sleeve, thereby obtaining ON-OFF signals. Since the sleeve is completely sealed, no steam or corrosive gases from the tank can enter the container housing the switch mechanism. By arbitrarily setting the float stopper, signals can be obtained at level positions that meet specifications. It is widely used for upper and lower limit alarms, pump control, valve opening and closing, and more.

Float Switch LS Series

Float Switch LS Series

Your single-phase pump will be transformed into an automatic pump.

You can easily operate it automatically just by connecting it to a power plug. The operating water level and stop water level can be easily adjusted. When the water level rises, the power turns ON, and when it falls, the power turns OFF, so it can be used for purposes other than pumping.
