Vibrating oxygen probe

摘要

A vibrating oxygen probe arrangement for measuring the oxygen content of molten steel bath and the like including an elongated lance pivotally mounted on a frame work which carries a vibrating motor driving an arm or connecting rod which in turn is connected to the lance above its pivotal connection to the frame and wherein the lower end of the lance has connected thereto an oxygen probe including an oxygen sensing cell structure to determine the concentration of the oxygen in the molten bath, the frame structure being provided with handles so that an operator may carry the vibrating lance and place the same in the vessel, the connecting rod having a universal connection with the rotary collar connected to the lance and with the eccentric pin connecting with the cam driven by the motor eccentrically. The lance is pivotally carried by trunnion bars which pivot in adjustable supports mounted on the frame, the trunnion bars adjustably connected to an adjustable collar of the split ring type that surrounds and holds the lance below the connecting rod coupling to the lance.
