Differential force type magnetic suspension water level gauge

Abstract

This invention relates to a differential force type magnetic suspension water level gauge, which comprises a containment drum connected to the boiler by two pipes, a measurement hammer stable suspended in the drum by the interaction of n=magnetic fields formed by following alnicos, an inner alnico fixed on hammer upper end by an inner alnico sheath, a bracket with lower end fixed on the drum, a tension transmitter fixed on bracket upper end, an outer alnico connected to the transmitter measurement end by an outer alnico sheath, and a water-level display secondary meter connected to the signal output end of the transmitter. This invention can measure continually with high precision.

Description

technical field [0001] The invention belongs to the technical field of water level measurement and relates to a differential force magnetic levitation water level gauge. Background technique [0002] At present, there are many measurement methods in the field of water level measurement, such as: local direct reading water level gauge, differential pressure water level gauge, electric contact water level gauge, magnetic levitation water level gauge, etc. Although these water level gauges have their own characteristics, they also have their own defects. For example, the local water level gauge is easy to leak, and the mica sheet is fouled, which seriously affects its display effect; the electric contact water level gauge measures the water level through the electrode, and the electrode The number of settings is limited, and there is a certain interval between the electrodes, which reduces the measurement accuracy and cannot eliminate the problem of blind spots; the differentia...

Problems solved by technology

Although these water level gauges have their own characteristics, they also have their own defects. For example, the local water level gauge is easy to leak, and the mica sheet is fouled, which seriously affects its display effect; the electric contact water level gauge measures the water level through the electrode, and the electrode The number of settings is limited, and there is a certain interval between the electrodes, which reduces the measurement accuracy and cannot eliminate the problem of blind spots; the differential pressure water level gauge measures the water level through the reference water level of the water, and cannot be real-time because there is no reference water level when starting the furnace. Put into operation; the magnetic levitation water level gauge measures the water level by measuring the position of the float, and the float must overcome its own gravity and the friction between the float and the inner wall of the container when it floats upward under the action of buoyancy, which will inevitably bring about hysteresis problems and reduce the measurement accuracy
