Abstract

A magnetostriction liquid level sensor comprises a liquidometer, a measuring rod and a floating ball. The measuring rod comprises a PTFE lining tube, a copper tube, an insulating protection layer, an outer tube, a waveguide wire, a waveguide wire fixing piece, springs, a wave absorbing positioning rubber stick, a return welding line and a bottom end choke plug. The PTFE lining tube is installed in the copper tube, and the lower end of the PTFE lining tube is connected with the spring. The insulating protection layer is arranged between the copper tube and the outer tube. The lower end of the waveguide wire is connected with the return welding line. The wave absorbing positioning rubber stick and the waveguide wire are connected and fixed into the copper tube through the waveguide wire fixing piece. The periphery of the waveguide wire fixing piece is connected with the springs. The bottom end choke plug is installed at the lower end of the outer tube and fixes a device inside the outer tube. The liquidometer and the floating ball are connected with the measuring rod. The magnetostriction liquid level sensor is high in precision, reliable in stability, long in service life and convenient to install.
