OEM/ODM UQK - 6000/6100 Displacer high pressure high temperature Level Switch 

 We are one of the repute's manufactures in China, we produce the level gauges and flow meters. Our products are Magnetic level gauges, glass tubular level gauges, glass sheet level gauges(transparent type and reflective type, sight glass level gauges), drop-in type level gauges, capacitive level gauges, level indicator, level transmitter and sensor. Flow meters: Metal rotary flow meters, vortex flow meters and turbine flow meters, electromagnetic flow meters, oval gear wheel flow meters, precession vortex flow meters and roots flow meters.
A displacer is fixed on a stainless steel cable. Its density is higher than

the measured density. So it always prolongs the spring.

Underfree condition,the spring is prolonged to preset length and keep the spring within certain elastic limit by a stainless steel stopper. The first magnet is located in the spring guide rod and moves up and down as the spring expanding or contracting.

There is an up/down adjustable switch outside pressure pipe in the housing. As liquid level rising and the displacer immersed, the increased volume of buoyancy force is equal to the weight force of displaced liquid volume by Archimedes principle. As spring elastic force diminishing and spring constriction, the first magnet will move up to trigger the mechanical switch. When the level decreasing, displacer emerges from liquid level, spring receives that added force, and spring increases  to a certain length, the first magnetic switch move and the switch is reset to former state by action of first switch.
