The new Levalarm GOLD switch represents a major step forward in reliability. It employs the same interlocking magnet operation used by Clark Clark-Reliance in its Jerguson Level Switches for over 28 years. Here’s how it works:
A stainless steel float is attached to the end of a rod with a stainless steel encapsulated magnet. The magnet travels vertically in the pressure tube. The primary magnet on the float rod inside the pressure tube drives the secondary magnet, which in turn drives the tertiary magnet. The tertiary magnet is mounted to the switch arm and activates the switch. The use of repelling magnetic fields create a positive interlocking switch that is vibration resistant.
A buoyed float will cause the reaction of the magnets to hold the switch open or closed, depending on which switch terminals are used. As liquid falls in the chamber, the float drops and directs the magnets to the opposite position which activates the switch in the opposite direction.
